Writing a flawless PhD thesis requires much more than only subject matter expertise. It requires expertise, experience, and in-depth thinking, along with sharp intelligence. Though most students add a discussion chapter in their thesis or dissertation, many of them end up messing up the essay or missing out the central issues.

A discussion chapter in a PhD thesis is a place where you have the chance to delving into the analysis, importance, and relevance of your research. This section focuses on explaining and analyzing what you have researched, presenting how it is associated with the existing literature. It is also a place for argument supporting your entire discussion. We often find that people seek thesis writing help from experienced editing and proofreading services to prepare a flawless PhD discussion chapter. However, the following 9 essential tips can help you design a perfect PhD thesis with an excellent discussion chapter.

1. Understand the objective of your PhD thesis

Before setting out to conduct a PhD thesis, researchers design and plan a study with objective(s) in mind. Such objectives inform how the dissertation is conducted. For example, no researcher would just commence by administering questionnaires or setting up laboratory equipment without an objective. It also informs the questions and necessary procedures to undertake. To write a well-conveyed discussion section in PhD thesis, the author must review and ascertain whether the conducted study addressed these objectives. It takes the understanding of the objective to assess the achievement of the objective clearly. Based on the assessment, the author finds the direction of his discussion. The comprehension of this objective is critical to crafting a focused discussion section in scholarly writing.

2. Determine a clear structure

The first step in organizing a perfect discussion chapter for a PhD thesis is to divide them into separate sections that move from a particular result to implications. However, depending on your PhD thesis topics, you may utilize the followings:

Analyze and summarize your main findings.

Evaluate how the results reflect the literature review.

Show if the discussion impacts the original hypothesis and, if yes, how it affects your hypothesis.

3. Usage of grammar and tense

The proper usage of grammar and tense is a key to a seamless PhD thesis. The improper use of grammar and tense can have the worst impact on the entire dissertation, along with the discussion chapter . Depending on the context, the usage of past and present tense should be made. When you are referring to specific data, the present tense can be used. For instance, when the light increases, speed decreases. However, while summarizing the result or concluding something, past tense can be used. For example, between 2013 and 2016, the number of car accidents decreased visibly. However, depending on the context, you can combine two tenses. Also, bear in mind that different manuals might require different tenses.

The tense adopted by the study should be uniform. Try to write the discussion chapter of your PhD thesis in the required tense format of your guideline. For instance, The  APA Publication Manual  provides suggestions on which verb tense is appropriate for various sections of a thesis:

Past tense or present perfect tense for the literature review and "the description of the procedure if the discussion is of past events."

"Use past tense to describe the "

"Use the present tense to discuss the implications of the results and to present the conclusions. By reporting conclusions in the present tense, you allow all readers to join you in deliberating the matter at hand."

As much as possible, try to be consistent with your chosen verb tense within a section as doing so "can help ensure smooth expression."

It is always best to check with your manual to get their opinion on the best approach for your thesis.

4. Referring to hypotheses and literature review

The primary purpose of referring to the literature review is to contextualize your discussion chapter as a part of the debate. For instance, suppose you introduce a theory claiming that speed cameras have zero effect on a road’s fatalities. You need to describe how your findings relate to this assumption. The same applies while making a hypothesis. Never forget this fact while discussing your results.

5. Evaluate your results and compare them with existing studies

While writing the discussion chapter of your PhD thesis, you need to analyze your results rather than just simplifying it. Don’t forget to do complete research on if your results agree or conflict with the previous studies.  You need to evaluate if there are any differences and, if yes, what the differences are. Comparing the development with existing studies helps your research to connect any existing debate. It also offers a solid base of conclusions.

In a well-written discussion chapter of a PhD thesis, an author should compare his/her findings with those of other studies reported in the literature. This aspect is different from a literature review in the sense that the author has data at hand to compare, as against the general overview made about a thesis’s objectives prior to the investigation. In comparing, the author is able to pronounce the authenticity of the results, especially when similar procedures were used in other studies. Any differences in findings can be explained using the different peculiarities between the author’s study and others. If this consideration is carefully made and implemented, the author may likely find evidence-based explanations for his/her findings. Even for novel findings, an author may still find relevant literature that formed the rudiments of the present study to discuss the progress, contribution, and novel dimension of the study. 

6. Why should the findings of your PhD thesis matter?  

After discussing the study results, the author, as part of his goal, must propose the impact of the study’s findings on the problem that informed the idea of the thesis. The reader will be better served if the author describes a roadmap for solving the problem based on the findings. Depending on the nature of the problem, an author may propose solutions to affect policy, behavioral change, or conventional practice. Only after making this contribution will a discussion section expose readers to the specific and general impacts of a PhD thesis.

7. Understand the limitation of your research

It is one of the most important things to evaluate when writing a discussion chapter for your PhD thesis. The discussion chapter of your research paper should involve some acknowledgment of the study limitations. Suppose you have critically assessed similar studies in the literature review; you are free to compare your work against their weakness or strength.

8. Don’t be afraid to be unique

The focus on research may change and evolve with time if you are working on a long-term project. The key to adjusting the focus on the literature review is to reflect these changes. Suppose you may find that specific themes are more prominent than others; it is helpful if you review your literature review and tweak them to emphasize the themes. Never be afraid to be unique to bring the changes.

9. Don’t forget to avail a professional thesis editing and proofreading service

Last but not least, you can seek assistance from professional editing and proofreading services. Taking PhD thesis help from professional editing and proofreading services doesn’t only facilitate the writing process but also helps you execute a flawless PhD thesis with a well-formed and informative discussion chapter.

Joe Eckel is an expert on Dissertations writing. He makes sure that each student gets precious insights on composing A-grade academic writing.

First and foremost, students need to have a clear understanding of what dissertation discussion is. This is not the same as your results section , where you share data from your research. You are going deeper into the explanation of the existing data in your thesis or dissertation discussion section. In other words, you illustrate practical implications of your research and how the data can be used, researched further, or limited.  What will make your discussion section of a dissertation excellent:

This section should go after research methodology and before the dissertation conclusion . It should be directly relevant to questions posed in your introduction.  The biggest mistake you can make is to rewrite your result chapter with other words and add some limitations and recommendation paragraphs. However, this is an entirely different type of writing you need to complete.

A dissertation discussion section is critical to explaining students’ findings and the application of data to real-life cases. As we mentioned before, this section will often be read right after the dissertation methods . It evaluates and elaborates on findings and helps to understand the importance of your performed thesis research.  A dissertation discussion opens a new perspective on further research on the same field or topic. It also outlines critical data to consider in subsequent studies. In a nutshell, this is the section where you explain your work to a broad audience.

Let’s start your writing journey of this research part with a clear delineation of what it should include and then briefly discuss each component. Here are some basic things you need to consider for an excellent discussion chapter of dissertation :

One of the most commonly asked questions for our experts is how to write the discussion section of a dissertation or thesis. We understand why it can be complicated to get a clear answer. Students often think that this section is similar to the result chapter and just retells it in other words. But it is not so. Let’s go through all steps to writing a discussion in a dissertation, and share our best examples from academic papers.

Writing the discussion chapter of a dissertation is not a big deal if you understand its aim and each component in a text structure. First of all, you need to evaluate how your results help to answer research questions you defined in the beginning. It is not about repeating the result, you did it in previous paragraphs.  However, dissertation or thesis discussion should underline how your findings help to answer the research problem. Start writing from a brief intro by recalling research questions or hypotheses . Then, show how your results answer them or support a hypothesis in your work.

Next part of your discussion for dissertation is to provide a short summary of previous data. But do not respite the same summary paragraphs from results or introduction of a dissertation . Here researchers should be more thoughtful and go deeper into the work’s aims.  Try to explain in a few sentences what you get from running research. For instance, starters usually write the statement that “our data proves that…” or “survey results illustrate a clear correlation between a and b that is critical for proving our working hypothesis…”.  A discussion chapter of your dissertation is not just a fixation on results but a more profound summary connected to research goals and purpose. Here is an example: Summary of Findings Example

The most critical part of a discussion section is to explain and enact the results you’ve got. It is the most significant part of any text. Students should be clear about what to include in these paragraphs. Here is some advice to make this elaboration structured:

Writing a dissertation discussion chapter can be tough, but here is a great sample to learn from. Example of Interpretations in Disssertation Discussion

Here we came to the implications of your findings for the dissertation discussion. In other words, this is a few sentences on how your work is connected to other studies on the same research topic or what literature gap you are going to fill with the data and research you launched. Remember to mention how your study address the limitations you have discovered while writing a literature review .  First, outline how your hypothesis relates to theories or previous works in the field. Maybe, you challenged some theories or tried to define your own. Be specific in this section. Second, define a practical implementation of your work. Maybe, it can support recommendations or change legislation.  Discussion chapter of a thesis is a place where you explain your work, make it valuable, and incorporate additional meaning for some specific data.  Example of Implications in Disssertation Discussion

It is pretty tricky to conduct research without limitations. You will always have some, which does not mean that your work is not good. When you write a discussion chapter in a thesis or dissertation, focus on what may influence your results and how changing independent variables can affect your data collection methods and final outcomes.  Here are some points to consider when you structure your dissertation discussion limitation part:

Critical thinking and analysis can help you to outline possible limitations. It can be the age of the reference group, change of questionnaire in a survey, or specific use of data extraction equipment. Be transparent about what could affect your results.  Example of Complications

Writing a dissertation discussion also makes a connection to possible future research. So, other scientists may complete that. While elaborating on possible implementations of your study, you may also estimate future approaches in topic research.  Here are some points to consider while your discussion in thesis writing:

Example of Recommendations

You are almost done, the last step is to provide a brief summary of a section. It is not the same as a conclusion for whole research. However, you need to briefly outline key points from the dissertation discussion.  To finalize writing the discussion section of a dissertation, go through the text and check if there is no unimportant information. Do not overload the text with relevant data you did not present in the result section. Be specific in your summary paragraphs. It is a holistic view of everything you pointed out. Provide a few sentences to systemize all you outlined in the text. Example of a Concluding Summary in a Dissertation Discussion Section

StudyCrumb provides the best samples from real students' work to help you understand the stylistic and possible structure of this part. It does not mean you need to copy and paste them into your work.  However, you can use a  dissertation discussion example for inspiration and brainstorming ideas for breaking writing blocks.

  • Interpretations This is a critical component of your work — elaborate on your results and explain possible ways of using them.
  • Implication Research work is not just 100+ pages of text. Students should explain and illustrate how it could be used for solving practical problems.
  • Constraints This is where you outline your limitations. For instance, your research was done only on students, and it may have different results with elderly people.
  • Recommendations You can also define possible ways of future research on the exact topic when writing a discussion for your thesis or dissertation. Tell readers, for example, that it would be helpful to run similar research in other specific circumstances.
  • Identify correlations or patterns in the data for dissertation discussion.
  • Underline how results can answer research questions or prove your hypothesis.
  • Emphasize how your findings are connected to the previous topic studies.
  • Point out essential statements you can use in future research.
  • Evaluate the significance of your results and any unexpected data you have.

  • Outline questions related to your topic that you did not answer in defined study or did not outline as research questions. There are other possible gaps to research.
  • Suggest future research based on limitations. For example, if you define surveyed people’s age as a limitation, recommend running another survey for older or younger recipients.
  • Be consistent Your dissertation discussion chapter is a part of bigger research, and it should be in line with your whole work.
  • Understand your reader You are writing an academic text that will be analyzed by professionals and experts in the same field. Be sure that you are not trying to simplify your discussion.

  • Be clear Do not include any data that was not presented in the result section.
  • Consider word choice Use such terms as “our data indicate…” or “our data suggests…” instead of “the data proves.”

According to the data, implementing the co-orientation theory was successful and can be used for the same circumstances in the future. As we found, most participants agreed with the importance of those theses on the five fundamental reforms. It means that the results identified a successful government work in choosing the messages to communicate about examined reforms. At the same time, the situation is not so favorable with implementing the principles of two-way symmetrical communications. According to the results, people did not feel that the government had a mutual, open, and equal dialogue with the public about the reforms.
Our study underlines the importance of future research on using TikTok for political communication. As discussed above, TikTok is the most commonly used social media platform for many young voters. This means that political discussion will also move to this platform. Our research and typology of political communication content can be used in the future planning of effective political campaigns. For example, we can assume that “play videos” have enormous potential to facilitate complicated topics and provide specific agenda settings. We also identified additional affordances of TikTok used for political communication, such as built-in video editors, playlists for specific topics, a green screen for news explainers, and duets for reflection on news and discussion. It means that these features make TikTok suitable for efficient political communications.
As we pointed out in the literature review, there are few works on using TikTok affordances for political communications, and this topic can be expanded in the future. Government institutions have already understood the importance of this platform for efficient communication with younger audiences, and we will see more political projects on TikTok. That is why expanding research on using TikTok for political communication will be enormous in the following years. Our work is one of the first research on the role of emerging media in war communication and can be used as a practical guide for government's strategic planning in times of emergencies.
Although this study has provided critical first insights into the effects of multimodal disinformation and rebuttals, there are some limitations. First and most importantly, the effects of multimodal disinformation and rebuttals partially depend on the topic of the message. Although fact-checkers reduce credibility of disinformation in both settings, and attitudinal congruence plays a consistent role in conditioning responses to multimodal disinformation, visuals do not have the same impact on affecting the credibility of news on school shootings and refugees.
As we mentioned before, our study has some limitations, as the research was conducted based on data from United State citizens. However, for a better understanding of government communication practices, it would be productive to implement the same research in other countries. Some cultural differences can influence the communication strategies the government uses in times of emergency. Another possible way to examine this topic is to conduct research using a specific period of time. For future studies, it will be beneficial to expand the number of survey recipients. 
To summarize, Airbnb has expertise in communicating CSR and CSA campaigns. We defined their communication strategy about the program for Ukrainian refugees as quite successful. They applied all the principles of CSR communication best practices, used dialogic theory to engage with the public on social media, and created clear messaging on applying for the program. Airbnb examples of CSR communication can be used by other businesses to create a communication strategy for unplanned CSR campaigns. Moreover, it can be further researched how Airbnb's CSR campaign influenced the organizational reputation in the future.

12 Steps to Write an Effective Discussion Chapter

November 5, 2016 by Dissertation Genius

This article gives doctoral dissertation students valuable guidance on how to go about writing their Discussion chapter. The article starts by outlining the main goals and writing approaches. Then the article explains 12 specific steps to take to write an effective discussion chapter.

Discussion Chapter: Main Goals and Writing Approaches

You should always keep in mind the main goals when writing your Discussion chapter. These include stating your interpretations, declaring your opinions, explaining the effects of your findings, and making suggestions and predictions for future research.

With the main goals mentioned, it is interesting to note how to go about writing this chapter. To do this, follow three important suggestions:

  • Answer those questions posed in the introduction (central research questions)
  • Show how the answers are supported by the results
  • Explain how the answers fit relative to the existing body of knowledge about the subject

Keep in mind that the Discussion chapter can be considered the most important part of your dissertation. Therefore, don’t be surprised if you may need more than one writing attempt for this chapter.

The 12 Steps to an Effective Discussion Chapter

To make sure your message remains crystal-clear, the Discussion chapter should be short and sweet, but it should fully state, support, elaborate, explain, and defend your conclusions. Take great care to ensure the writing is a commentary and not simply a regurgitation of results. Side (distracting) issues should not be written about because they will cloud the essence of your message. There is no perfect dissertation, but help your reader determine what the facts are and what is speculation.

Here are 12 steps to keep in mind when writing your Discussion Chapter:

  • Always try to structure your Discussion chapter from the ‘specific’ to the ‘general’: expand and transition from the narrow confines of your study to the general framework of your discipline.
  • Make a consistent effort to stick with the same general tone of the introduction. This means using the same key terms, the same tense, and the same point of view as used in your introduction.
  • Start by rewriting your research questions and re-stating your hypothesis (if any) that you previously posed in your introduction. Then declare the answers to your research questions – make sure to support these answers with the findings of your dissertation.
  • Continue by explaining how your results relate to the expectations of your study and to literature. Clearly explain why these results are acceptable and how they consistently fit in with previously published knowledge about the subject. Be sure to use relevant citations.
  • Make sure to give the proper attention for all the results relating to your research questions, this is regardless of whether or not the findings were statistically significant.
  • Don’t forget to tell your audience about the patterns, principles, and key relationships shown by each of your major findings and then put them into perspective. The sequencing of this information is important: 1) state the answer, 2) show the relevant results and 3) cite the work of credible sources. When necessary, point the audience to figures and/or graphs to ‘enhance’ your argument.
  • Make sure to defend your answers. Try to do so in two ways: by explaining the validity of your answer and by showing the shortcomings of others’ answers. You will make your point of view more convincing if you give both sides to the argument.
  • Also make sure to identify conflicting data in your work. Make a good point of discussing and evaluating any conflicting explanations of your results. This is an effective way to win over your audience and make them sympathetic to any true knowledge your study might have to offer.
  • Make sure to include a discussion of any unexpected findings. When doing this, begin with a paragraph about the finding and then describe it. Also identify potential limitations and weaknesses inherent in your study. Then comment on the importance of these limitations to the interpretation of your findings and how they may impact their validity. Do not use an apologetic tone in this section. Every study has limitations.
  • Conduct a brief summary of the principal implications of your findings (do this regardless of any statistical significance). Make sure to provide 1-2 recommendations for potential research in the future.
  • Show how the results of your study and their conclusions are significant and how they impact our understanding of the problem(s) that your dissertation examines.
  • On a final note, discuss everything this is relevant but be brief, specific, and to the point.

How To Write A Discussion Chapter In Your PhD Discussion

If you’re here, you probably got to the part in your thesis or dissertation where you have to work on the discussion chapter. Don’t worry; we’re here to help! In this article, we’ll break down the discussion chapter in simple language and give you lots of examples to make it easier to understand.”

What is the discussion chapter?

The discussion chapter plays a vital role in your thesis or dissertation.

Unlike the results chapter, which presents your analysis findings, whether they are qualitative or quantitative, this chapter is where you really dig into your results.

Here, you’ll interpret and explain your research findings, exploring their significance and implications.

In this section, you’ll connect your research findings with your research questions or hypotheses and link them back to previous studies and literature, as you did in your literature review chapter.

You’ll also assess the relevance and importance of your findings to your field of study and make a persuasive argument for the conclusions you’ve drawn from your analysis.

In essence, the discussion chapter is your opportunity to engage with and elucidate your research findings in a comprehensive and cohesive manner.

What to Incorporate in the Discussion Chapter?

Let’s start with the basics: in certain studies, the results and discussion chapters are merged into a single chapter.

Whether this applies to your work depends on the type of study you conducted, including its nature and chosen methodology, as well as the guidelines set by your university.

In essence, your discussion chapter’s primary purpose is to dissect, delve into the meaning of, and establish the significance of the data you presented in the results chapter. Here, you will infuse your results with significance by critically evaluating and interpreting them.

This process aids in addressing your research questions, achieving your research objectives, and bolstering your overall conclusions. Therefore, your discussion chapter should squarely focus on findings that are directly relevant to your research objectives and questions.

Since this chapter mirrors your results chapter, it’s imperative that you refrain from introducing any new findings.

In simpler terms, you should avoid making claims in this section if you haven’t already presented the pertinent data in the results chapter.

Hence, ensure that each discussion point you raise in this chapter corresponds to the data analysis covered in the results chapter.

Crafting the Discussion Chapter: A Step-by-Step Guide

Now that you’ve grasped the essence of the discussion chapter and its essential elements let’s delve into structuring this pivotal chapter. In a broad sense, you can break down this chapter into six key components, which serve as sequential steps in the chapter-writing journey.

Step 1: Reiterate Your Research Problem and Questions

When you begin writing your discussion chapter, the first thing to do is remind your reader about what your research is all about, like the main problem you’re trying to solve and what questions you’re trying to answer. This reminder is important because, after reading a bunch of stuff, your reader might forget what your research was really about or get distracted by other things.

Step 2: Sum Up The Main Discoveries

Moving ahead, it’s time to sum up the most important thing you found in your results chapter. Now, this might look different if you did qualitative or quantitative research. Qualitative research could be all about themes and connections, while quantitative research might talk about things like correlations and reasons behind everything happening.

Usually, this part doesn’t need to be long, just a paragraph or two, depending on how many research questions you had. Try to keep it short because you’ll go into more detail later on in the chapter.

Here are some examples of what you might say:

The analysed data suggest that…

The data support/oppose the defined theory that…

The detailed analysis identifies…

Remember, these are just examples. What you say here depends on the questions you were trying to answer in your research, so make sure you address them correctly.

Step 3: Interpret your results

Once you’ve started your research problem and questions and given a quick rundown of what you found, it’s time to explain your discoveries by looking at your results more closely.

But remember, only talk about what you already told them in the results part – don’t bring in new information.

From a structure point of view, it might be a good idea to organise this chapter, kind of like how you did the results one. This makes it easier for your reader to follow along and understand your points better.

Here are a few things to think about while you’re explaining your findings:

  • How do your results match up with what other studies found?
  • If your results are different from other studies, why do you think that happened?
  • What do your results add to your field of research?
  • Are there any other reasons your findings could be the way they are?

When you’re explaining your findings, make sure not to say anything that doesn’t have proof. Every idea you put out there should have something to back it up, like data or facts (and you already put that in the results chapter).

Step 4: Admit the Flaws in Your Research

Now, in the fourth step of making your discussion chapter, it’s time to fess up about the things that didn’t go so well in your study. These could be problems in any part of your study, like how big or small it was, the theories you used, how you did your analysis or even the group of people you studied.

Some folks might feel like talking about what went wrong is like shooting themselves in the foot. But that’s not true! Actually, one of the signs of doing really good research is being honest about what didn’t work out. So, saying what went wrong is actually a strong move, not a weak one.

Step 5: Offer Some Suggestions for What Comes Next

Now, after you’ve talked about your findings and owned up to what didn’t go perfectly, it’s time to think about two important things:

  • How can other students use your findings in real life? Basically, what good can come out of your research in the field or industry? Where can people put this info to use, and how would they do it?
  • What about future research? How can other researchers take what you’ve done and build on it? Maybe they can make your findings even better by dealing with the issues you mentioned earlier. While you’re at it, check if your results match up with what other studies have found, and if not, figure out why.

Final Words

By adhering to these fundamental principles, you will not only construct a well-organised discussion chapter but also contribute significantly to the ongoing discourse in your field. This, in turn, elevates the impact and relevance of your research within the broader academic community.

The Final Chapter(s): Discussion, Conclusion, Limitations and Implications

Posted by Rene Tetzner | Oct 21, 2021 | PhD Success | 0 |

The Final Chapter(s): Discussion, Conclusion, Limitations and Implications

4.5 The Final Chapter(s): Discussion, Conclusion, Limitations and Implications

In some theses, the discussion of the study, its results and any concluding thoughts will fill more than one chapter: there may be, for instance, a chapter dedicated to discussion and a shorter conclusion chapter, or perhaps two chapters dedicated to discussing the results of different methodologies and a final chapter on relationships between those different results. In many theses, however, a single chapter will suffice for both. This final part of your thesis is a vital one: it tends to synthesise and analyse all elements of the thesis in order to evaluate and explain the overall significance of the research, and readers will often turn to the discussion (or conclusion) chapter first to obtain an overall picture of a study. The structure of this all-important final material varies considerably from thesis to thesis, yet it is essential that it be designed in a way that allows you to move through a great deal of potentially complicated, analytical and speculative information in an orderly fashion. Considerable reflection is therefore necessary before beginning to write, and not only to get the structure right. That structure depends, of course, on exactly what you intend to include in your discussion chapter(s), and deciding on exactly what to say will take some deep reflective thought on your part.

You may wish to address your plans for your discussion and conclusion chapter(s) with your supervisor and other committee members, and it is also a good idea to see if your department has any guidelines for this part of the thesis, especially if you are feeling unsure about how to proceed and could use some practical advice. In the final analysis, however, you are better acquainted with your research and thus better able to make sense of it than anyone else can be, so you are the only person truly qualified not only to write, but also to design the discussion and conclusion for that research. Besides, this final part of the thesis is your opportunity to express your own perspective and opinions on the significance of your doctoral research, based firmly, of course, on the topic, problem or phenomenon you investigated, your aims and objectives, the methods you used and the results you achieved.

Unfortunately, you may well feel rather exhausted by the experience of drafting your thesis by the time you arrive at your discussion chapter(s), but detailed analysis, intellectual vigour and creative connections are absolutely necessary for discussing and concluding your thesis, and a little passion never hurts either. Doing less than your best at this point would compromise all the effort you have already invested, so take a deep breath and dive into what can in fact be the most challenging and pleasurable part of writing a thesis. There is no simple or universal recipe for successfully discussing and concluding a doctoral thesis and its research, but, generally speaking, an inversion of your opening chapters takes place: in those chapters, you moved your reader from the more general background and scholarship associated with the topic, problem or phenomenon to focus on your particular perspective and approach; in your final chapter(s), you need to use the specific focus you adopted and the results you achieved to move your reader back out to the more general interpretations and implications of your research. In order to achieve this, there are a number of practical approaches and standard expectations that are worthy of serious consideration before forging your own unique path through the forest of possibilities.

how to write general discussion for phd thesis

Discussing and concluding a thesis effectively might and generally should involve:

  • A brief introduction outlining the structure and content of the chapter(s). This can take the form of a single short paragraph, but because the discussion section of a thesis tends to be creative and is always unique, and it is essential that readers understand exactly what you intend, an opening paragraph of this sort can be extremely helpful for clarifying your approach and raising appropriate expectations.
  • A brief but informative summary of the study or thesis as a whole. This need only highlight the major issues and can be done efficiently by moving through the individual chapters as outlined in the following four points.
  • A return to the introduction of the thesis to restate the most important material introduced there. The research topic, problem or phenomenon should certainly be emphasised, as should its significance, your aims and objectives, and any research questions and hypotheses you introduced and used as guiding factors in your research. You will need to analyse how your research and results answer, resolve and contribute to knowledge in relation to these elements, so any or all of them can effectively be used to structure the chapter, especially if you have used them to organise your report of the results. You may also want to return to the essential aspects of the background and context of your research as discussed in the introduction chapter, but this tends to be necessary only if that background and context is immediately relevant to your discussion and concluding thoughts.
  • A return to the literature review to highlight the most important aspects of previous research on your topic and any key theories related to your work in the thesis. Any gaps, misconceptions and limitations that you identified in the scholarship in your earlier literature review should be restated with the goal being to explain exactly how your research and its results have provided what was lacking, established new ways of looking at the problem(s) and thus moved beyond the traditional views and limitations. Your thesis should make an original contribution to knowledge and discussing it in relation to previous scholarship in the area is one of the most effective ways to identify, emphasise and explain that contribution.

how to write general discussion for phd thesis

  • A return to the description of your methodology. This need not be long or detailed, but it sometimes is, and reviewing your main methods and approaches with an eye to evaluating their reliability, limitations and overall effectiveness is an important part of assessing your research. Your understanding of the appropriateness of your methodology may have changed since you first designed your study, particularly as you analysed and reported your results. Your methods may have exceeded or failed to live up to your expectations, or they may have presented limitations or complications you had not envisioned. You may have made errors while putting your methods into practice. Whatever the reality of your methodology proved to be should be explained accurately and objectively, so this is a place for complete if sometimes painful honesty.
  • A return to the report of your results to summarise and highlight the key points. There is no need to go through your results in detail – the chapter(s) immediately preceding your discussion has already done that – but since you will need to use the results to discuss the implications and limitations of your research, mentioning the main trends is essential. You should focus particularly on the aspects of your results that you intend to discuss, but try not to leave out any significant or meaningful findings, including surprises, whether they support your research hypotheses or not. Focus and brevity can be achieved by making general statements about the nature of the results and following each statement with the most important examples and details to support it.
  • An analysis and interpretation of your research as a whole and its results. This can be included in a step-by-step manner along with the summaries mentioned in the last four points above, or it can be tackled separately after the relevant information from previous chapters has been highlighted. Your approach, like your ideas, for this part of your thesis will require a great deal of reflection and you may find that you have to begin more than once before finding the right direction. The essential question is ‘What does it all mean?’ and the answer can be notoriously difficult to identify and explain both thoughtfully and accurately. It is likely that your research and results will have many meanings, but this is your chance to express your own views and opinions. These should not be whimsical, erratic, biassed or overly subjective, however, but should be solidly and logically based upon your findings. Your interpretations and conclusions should be plausible, insightful and comprehensive, and whenever your ideas are tentative or speculative (as they will necessarily be at times when discussing matters such as causality), your language should clearly indicate that with phrasing such as ‘it seems that,’ ‘these results appear to suggest,’ ‘it is probable that’ and ‘the likely explanation is.’ It is also important to explain how your research and results have resolved the problem you explored, answered your research questions, tested your hypotheses, filled gaps in the scholarship on the topic, revealed the limitations of earlier theories, proved the validity of your methodology and achieved your aims and objectives. If you have not met with success in any of these areas, that, too, should be indicated.

how to write general discussion for phd thesis

  • An identification and analysis of the limitations of your study and its methodology. You may want to write this part along with the review of your main methods, but it can also work as a separate section of the chapter because limitations often extend beyond your methodology (to your findings, for instance). Identifying the limitations of your research and its results is a vital part of your thesis. You may prefer, of course, that there were no or very few limitations, but they are an inevitable aspect of any research, so recognising and discussing them not only demonstrates your intellectual maturity and critical skills, but also makes your research much more useful for future researchers in your area, including yourself. Limitations often stem from the nature of the research design and the exact qualities of the population or sample used, both of which might be called normal limitations that affect the generalisability of your research, but mistakes in controlling the relevant variables, defects in the instruments used or inadequate approaches to recording or analysing data will result in limitations (and perhaps unreliability) of a different kind. If any such limitations proved so significant that it was necessary to adjust your methods and/or repeat any of your research, a discussion of that process, the improvements you made and the ways in which the new results differed can be included as well, though you may want to consult your supervisor about this, as it might be more appropriate to discuss such changes in your methodology chapter(s) instead.
  • A discussion of the implications of your research and its results. This will tie into your comments about the significance of your research project as expressed in your introduction to the thesis, but your understanding of that significance may well have changed since you began writing, and you can provide further details as well as more certain conclusions in this chapter based on the results you have presented. Implications, whether for practical action or intellectual reflection, should obviously be directly related to the topic, problem or phenomenon you explored (it can be helpful to imagine what you would tell an audience affected by the problem or phenomenon if you had only enough time to emphasise a few major points), and good use can be made of your research questions and hypotheses as well as your aims and objectives as you construct your discussion. The implications you identify should be considered in relation to the background and context of your research as well as previous scholarship in the area, including both trials and studies of a more theoretical nature – ask yourself how your results build on the literature you reviewed and how your study integrates with or overturns current theories. You may also want to comment on the implications of your methodology, especially if it has been innovative, problematic or extraordinarily successful. You will have a great deal of freedom in expressing your thoughts about your work – the factual reporter of your results chapter has been left behind for the authoritative thinker of your discussion – but be sure that the implications you identify and explain are based firmly and logically upon your research and its results, and when you are theorising, generalising and speculating, ensure that your language accurately reflects those tentative modes.
  • One or more recommendations for future research in your area or discipline. Your recommendations for future research will be based to a large extent on the implications and limitations of your own research. It may be that some idealistic researchers start projects with the notion that their work will resolve all associated questions and problems, but this rarely (if ever) happens in reality, and often the answers that are derived from careful and extensive research complicate matters and open more doors on further research needs and possibilities. Your recommendations may involve repeating the kind of research you have done, but with changes that would eliminate the limitations you have identified (by adding controls, for instance, or choosing or developing different instruments, participants or means of analysis), or they may involve taking very different directions by conducting entirely different kinds of research (using entirely different methods perhaps, or focussing from a different perspective on the most unexpected or surprising trends of your results). Remember that your recommendations for future research can transform aspects of your work that may have proved disappointing into positive possibilities.
  • A brief conclusion. Since conclusions about your study are a major part of this chapter, a conclusion to it may seem somewhat redundant, but it is important to end on a bright clear note. Sometimes an academic or scientific author will dedicate pages of text to describing, interpreting and speculating upon all the sound and revealing results he or she obtained only to turn at the end of the final chapter to the limitations of the study, which can have the effect of dumping all the wind out of the sails he or she has so carefully and convincingly filled. It may be that the guidelines provided by your university or department call for limitations to be reported at the end of the thesis, and, as an essential aspect of valuable research, limitations need not be negative, especially if they are combined with or (if possible) followed by recommendations for future research. However, after discussing the limitations of your study, it can be useful to return to the unquestionably positive results and conclusions of your research. You might choose, for instance, three main concepts or conclusions that you would like to highlight as you close your text, and these can certainly be qualified with hints of limitations and recommendations while still emphasising the significant contributions of your research. Keep in mind that a doctoral thesis should make a significant and original contribution to knowledge, so highlighting the main ways in which it does so in your final thoughts is not out of place. If there was ever a time to blow your own horn a little, this is it.

Why PhD Success?

To Graduate Successfully

This article is part of a book called "PhD Success" which focuses on the writing process of a phd thesis, with its aim being to provide sound practices and principles for reporting and formatting in text the methods, results and discussion of even the most innovative and unique research in ways that are clear, correct, professional and persuasive.

how to write general discussion for phd thesis

The assumption of the book is that the doctoral candidate reading it is both eager to write and more than capable of doing so, but nonetheless requires information and guidance on exactly what he or she should be writing and how best to approach the task. The basic components of a doctoral thesis are outlined and described, as are the elements of complete and accurate scholarly references, and detailed descriptions of writing practices are clarified through the use of numerous examples.

how to write general discussion for phd thesis

The basic components of a doctoral thesis are outlined and described, as are the elements of complete and accurate scholarly references, and detailed descriptions of writing practices are clarified through the use of numerous examples. PhD Success provides guidance for students familiar with English and the procedures of English universities, but it also acknowledges that many theses in the English language are now written by candidates whose first language is not English, so it carefully explains the scholarly styles, conventions and standards expected of a successful doctoral thesis in the English language.

how to write general discussion for phd thesis

Individual chapters of this book address reflective and critical writing early in the thesis process; working successfully with thesis supervisors and benefiting from commentary and criticism; drafting and revising effective thesis chapters and developing an academic or scientific argument; writing and formatting a thesis in clear and correct scholarly English; citing, quoting and documenting sources thoroughly and accurately; and preparing for and excelling in thesis meetings and examinations. 

how to write general discussion for phd thesis

Completing a doctoral thesis successfully requires long and penetrating thought, intellectual rigour and creativity, original research and sound methods (whether established or innovative), precision in recording detail and a wide-ranging thoroughness, as much perseverance and mental toughness as insight and brilliance, and, no matter how many helpful writing guides are consulted, a great deal of hard work over a significant period of time. Writing a thesis can be an enjoyable as well as a challenging experience, however, and even if it is not always so, the personal and professional rewards of achieving such an enormous goal are considerable, as all doctoral candidates no doubt realise, and will last a great deal longer than any problems that may be encountered during the process.

How to Write an Effective Thesis Discussion

ScienceEditor

Writing an effective thesis discussion can be challenging because it is so open ended. The purpose of the discussion is to (1) interpret your results, (2) discuss the significance of your results, (3) place your work in the context of previous work, (4) discuss the limitations of your study, and (5) suggest next steps to advance understanding and/or to improve real-world situations. The discussion section should expand upon ideas presented in the introduction, literature review, and results, and sometimes even the materials and methods. It should convince the reader that your work was worthwhile.

General considerations

Throughout a thesis or other scholarly manuscript, the results of completed studies should be described in the past tense (e.g. "36 of 43 patients showed improvement with treatment A, while only 25 of 44 patients showed improvement with treatment B"). In contrast, present tense is used to describe ideas that currently appear to be true based on available evidence (e.g. "treatment A is more effective than treatment B for most patients"). A good thesis discussion will typically progress from discussing specific results to discussing broader concepts that currently appear to be true.

You should include citations and modifying statements as needed (e.g. "Previous work by Lee et al. (2017) found no difference in the effectiveness of treatment A compared to treatment B. However , their study was limited to patients in advanced stages of the disease."). You will also need to include suggestions for further research, which can be described in present tense (e.g. "Additional studies are needed to determine. . .") or future tense (e.g. "Future studies will determine . . .").

I will now move into more detailed suggestions for each part of the discussion. Notice the occasional use of first-person pronouns (e.g. "I suggest. . ." or "We believe. . ."), which is now generally acceptable in many fields if used sparingly. Check the specific guidelines provided by your graduate program (and target journal). Also notice the use of subheadings to break the text into shorter sections on specific topics, which is recommended for any long manuscript.

Discussion part 1: Interpret your results

Your discussion should relate directly to the research question(s) you presented in the introduction, so a good way to start the discussion is to clearly restate your research question(s) (e.g. "The current study aimed to determine whether treatment A or treatment B was better for patients with condition X.") The discussion section follows the results section, so the next obvious step is to state what you can conclude from your results (e.g. "We found that a higher percentage of patients showed improvement with treatment A than with treatment B, and therefore conclude that treatment A is more effective than treatment B for most patients with condition X").

There are two general strategies for structuring the discussion of results. The first strategy is to discuss the results in the same order as they were presented in the results section. Alternatively, you can discuss your most interesting or surprising results first. This second strategy is most effective when the results are especially novel. As with any manuscript, the goal is to keep your reader engaged.

In some fields, the thesis discussion is expected to include comments on all of the results, even minor results that may not be statistically significant (e.g. "Treatments C, D, and E produced results that were statistically indistinguishable from placebo, leading to the conclusion that they were ineffective at the concentrations tested."). Note that you should not just state the results (e.g. "Treatments C, D, and E produced results that were statistically indistinguishable from placebo"), but should also state a conclusion (e.g. "they were ineffective at the concentrations tested").

In some other fields, brief comments on minor results are typically included in the results section, and the discussion section is used to elaborate on the most noteworthy results. In some cases, it may be appropriate to write a combined "results and discussion" section, where results are presented alongside initial conclusions, and broader implications are discussed toward the end. Check the requirements for your graduate program (and target journal).

Discussion part 2: Discuss the significance of your results

Clearly explain what is gained from your research. Sometimes a study is very significant (e.g. These results are among the first to show that treatment A is more effective than treatment B for condition X."). Other times—especially for undergraduate or master's theses based on a few months of data collection—the results primarily provide information about what doesn't work (e.g. "These results indicate that treatments C, D, and E are ineffective at physiologically relevant concentrations.)

Discuss some of the possibilities that your research opens up (e.g. "These results raise the possibility that early treatment could improve daily life for patients with mild cases of condition X, and might even delay disease progression.) but do not overstate (e.g. "These results prove that early treatment will improve daily life for patients with mild cases of condition X, and will delay disease progression."). Be optimistic but realistic, whether your results are highly significant or not (e.g. "These results suggest that the solubility of molecules like C, D, and E need to be improved before they can be effective.").

Discussing the significance of your results (part 2 of this essay) is a natural extension of discussing what your results mean (part 1 in this essay), and may not require a separate section.

Discussion part 3: Place your work in the context of previous work

Put your work into a broader context. Here you should revisit some of the previously published work that was described in your introduction and literature review, and clarify how your work expands upon or challenges that work. Most importantly, you should discuss how your work advances understanding in your research field.

For a thesis based on disappointing data, your ability to effectively discuss previous work and potential future work can support the argument that you have developed the necessary skills to move forward in research. These skills are further demonstrated by many other aspects of a well-researched and well-written thesis.

In some cases, your results may reveal unexpected connections. This may require you to discuss additional bodies of work in the discussion section, which can become a second literature review section. As you may be starting to see, there are many different topics you can include in your discussion section. You need to choose your topics carefully, and cover them in sufficient but not overwhelming detail. You want your discussion to cover all essential information, remain a manageable length, and retain the reader's interest. All of the different possibilities can make writing your discussion section very challenging.

If your results contradict previous work, you need to provide some possible explanations. As a rationale scholar, it is especially important to consider all reasonable options. It could be that (1) the earlier work was flawed, incomplete, or not exactly comparable to your work, or (2) your work is flawed, incomplete, or not exactly comparable to the earlier work. You might not be able to determine the exact cause of the discrepancy, but contradictions provide an obvious way to transition into the next section.

Discussion part 4: Discuss the limitations of your study

Every study has limitations, and here you should discuss the major limitations of your research. What can't the results tell us? In what situations are the findings not relevant or well supported? There may be limitations due to your sample population, experimental techniques, data analysis, etc. Discuss these limitations honestly, but then explain why your study is useful despite these limitations. You might point out that your study included multiple different populations, different experimental techniques, alternative methods of data analysis, etc. You might also emphasize that your conclusions are limited to a subset of a larger population, and that additional work needs to be done to determine whether the same conclusions apply to a larger population. This brings us to our next point.

Discussion part 5: Suggest next steps to advance understanding and/or to improve real-world situations

Once you've placed your work into a broader context, you can imagine the future possibilities. Here you might discuss questions that remain to be answered, or questions that have been newly raised by your work. There might be specific studies that would be an obvious extension of your work, and/or exploratory studies that would shed light on promising areas for novel research. Alternatively, you might suggest ways in which your research could be applied to real-world situations to improve outcomes.

Many manuscripts and presentations end with a discussion of possible next steps. I tend to like this type of ending for discussions of basic research, such as which genes are activated in which cells. However, other people recommend always ending with conclusions, where you restate the main findings of your research in a compact form. This might involve a separate "conclusions" section or as a final paragraph in the "discussion" section. Ending with conclusions makes a lot of sense for studies that might directly impact real-world situations (e.g. Treatment A it more effective than treatment B for condition X.).

In any event, you should follow departmental recommendations, and end with a compelling and memorable message for your readers.

How to Write Your Thesis Discussion Section

how to write general discussion for phd thesis

The discussion section is the most critical aspect of your thesis. It is written after presenting your data in the results section. This article explains how to structure your thesis discussion section and what content is required.

What is the thesis discussion section?

The thesis discussion includes explanations and interpretations of your results in the context of your thesis question and  literature review , discusses their implications, acknowledges their limitations, and gives recommendations. In doing so, you make an argument to support your conclusion .

What should the thesis discussion section include?

  • A summary of your key findings
This analysis does not support the theory that…
  • The answer to your thesis question
These findings confirm our hypothesis that…
  • An interpretation of your findings
Our findings agree with the theory proposed by Jones (2019)…
  • The implications of your findings
The data provide new evidence of…
  • The limitations of your findings (i.e., what can’t the results tell us)
This study only included individuals living in urban areas, and the results may not be generalizable to populations in rural areas…
  • Suggestions of practical applications of your findings
X should be taken into consideration when…
  • Recommendations for further scientific investigations
Further studies are necessary to…

What should the thesis discussion section not include?

  • A restatement of all your results
  • The introduction of new results . All results in the discussion section must have been presented in the results section.
  • Speculations that can’t be supported by your data
  • Results that do not directly relate to your thesis question or hypothesis
  • Tables and figures (these are usually included in the results section)

How does the discussion overlap with other thesis sections?

The content in the thesis discussion section overlaps with the results section — the results section presents the data, and the discussion section interprets it. The structure of the discussion section differs according to the type of research ( quantitative vs. qualitative ). In qualitative research, such as in the Humanities and Social Sciences (HSS) domain, the discussion and results from sections are often combined. In thesis studies involving quantitative research, such as in the Sciences domain, these sections are usually written separately.

The content in the thesis discussion section also overlaps with the conclusion section — the discussion section presents a detailed analysis and interpretation of the data, and the conclusion section summarizes the main findings of the discussion. The discussion and conclusion sections may also be combined into a single section in some fields of study. If you are unsure of which structure to use, ask your supervisor for guidance and check the requirements of your academic institution.

How to write a thesis discussion

The discussion section of a thesis starts with an interpretation of the results and then places the findings in the general context of the field of study.

The discussion section is the most critical section of your thesis and will probably be the hardest to write. The discussion section of a thesis starts with an interpretation of the results and then places the findings in the general context of the field of study. This section also demonstrates your ability to think critically and develop innovative solutions to problems based on your findings, resulting in a deeper understanding of the research problem.

Because it can be daunting to write the thesis discussion section in one go, first prepare a draft according to the following steps:

  • Prepare an outline that broadly states your argument and how your results support it.
  • Strengthen your argument by mapping out how your results fit into the outline.
  • Place unexpected or controversial results in context and describe what may have caused them.
  • Go back to your literature review to identify any studies that you might want to delve into in greater detail given the findings of your study.
  • Identify study limitations.
  • Briefly summarize the importance and implications of your findings.
  • Recommend any practical applications of your study findings.
  • Suggest future work that could build on your findings or address study limitations.

Once you are happy with your draft, it’s time to finalize the thesis discussion section. Use the steps below as a guideline:

  • First, restate your thesis question and hypothesis that were stated in the introduction.
  • Then, use your findings to support the answer to your thesis question.
  • Defend your answers by discussing other studies with correlating results.
  • Explain how your findings consistently fit in with the current literature and mention how they address knowledge gaps in the field.
  • Mention studies that conflict with your findings, and try to explain possible causes of these contradictions (e.g., population size, inclusion and excision criteria, differences in data collection and analysis methods).
  • Address any unexpected findings. Describe what happened and then discuss the potential causes (e.g., a skewed response rate, sampling bias, or changes in the equipment used). Because they could have been caused by a flawed sampling method or an incorrect choice of methodology, carefully check that you have adequately justified your methodological approach. In extreme cases, you may need to restructure your hypothesis or rewrite your introduction.
  • Research studies are expected to have limitations and weaknesses. Mention all of them and how they may have impacted the interpretation and validity of your findings. Some limitations could highlight areas that require further study.
  • Summarize the practical applications and theoretical implications of your findings.
  • Recommend potential areas for future research.

How do I interpret my results?

The thesis discussion section must concisely interpret the results and assign importance to them. This is achieved by:

  • Identifying relationships, patterns, and correlations in the data
  • Discussing whether the findings support your hypothesis
  • Considering alternative explanations while also justifying your chosen explanation
  • Emphasizing novel results and explaining how they fill knowledge gaps
  • Explaining unexpected results and determining their significance

How do I discuss the implications of my results?

The discussion section of your thesis explains how your findings fit in with and contribute to the existing literature. This refers back to the literature review section of your thesis. The following questions should be addressed:

  • Are your findings supported by other studies, and do they add to the body of knowledge or address a gap?
  • Do your findings disagree with other studies? If so, determine or suggest the reason(s) why.
  • Do your findings challenge or support existing theories?
  • What are the practical implications of your findings?

How do I acknowledge the limitations of my study?

It is expected that all studies will have limitations. When discussing your study limitations, don’t undermine your findings . A good discussion of the limitations will strengthen your study’s credibility.

Examples of study limitations: sample size, differences in methods used for data collection or analysis, study type (e.g., retrospective vs. prospective), inclusion/exclusion criteria of the study population, effects of confounders, researcher bias, and robustness of the data collection method.

How do I make recommendations for future research?

Recommendations should either be included in the discussion or the conclusion section of your thesis, but not in both. This could include:

  • Addressing questions related to your study that remain unanswered
  • Suggesting a logical progression of your research study using concrete ideas
  • Suggesting future work based on the study limitations you have identified
Example: Future studies using a larger sample size from multiple sites are recommended to confirm the generalizability of our findings. Example: We suggest that the participants are re-interviewed after 5 years to determine how their perception of this traumatic experience has changed.

Tips for writing the thesis discussion section

  • Use subheadings to break down the discussion into smaller sections that identify key points.
  • Maintain consistency with the introduction  and  literature review sections. Use the same point of view, tone, and terminology.
  • Be concise .
  • Be logical. Present the discussion in the same sequence as the results unless there is an unexpected or novel finding that should be emphasized first.
  • Do not use jargon, and define all technical terms and abbreviations/acronyms.
  • Cite all sources. The majority of references cited in the thesis discussion section should be recent (i.e., published within the past 10 years).
  • Avoid plagiarism .

Thesis Discussion Writing Guide For All Levels

thesis discussion

A thesis discussion is the framing section of this paper. When writing this section, the author delves into the importance, meaning, and relevance of the results. The focus of this section should be on the explanation and evaluation of the findings. Here, you should show how your findings relate to the research questions and literature review. Your discussion should also make an argument that supports the overall conclusion.

The results and discussion in thesis form one of the most difficult parts to write. That’s because this section requires the author to think about the meaning and implication of their research. To be effective, the discussion chapter of a thesis should tell readers more about the meaning of the study and its importance. It should be well-written and organized to make it easier to read and understand.

Importance of Thesis Discussion

A discussion in thesis writing is a section that includes the interpretations and declaration of the writer’s opinions. It’s also the section where the writer explains the effects of their findings while making predictions and suggestions for future research. Here are some of the major reasons why the discussion section is important:

  • It answers the questions posed in the thesis introduction
  • It shows how the results of your research supported the answers to these questions
  • It explains how those answers fit in the existing knowledge body about your research subject

A Ph.D. thesis discussion chapter can be maybe considered very important. Therefore, you might have to make several attempts when writing this chapter. Our thesis writers can help you out if you got stuck.

How to Write a Discussion Chapter in a Thesis

There are different ways of writing discussion for thesis. But, this chapter should start with the reiteration of the research problem and a summary of the major findings. All reported data should not be repeated in this section. However, the section should include a statement of the results that answers the research question. This introduction should not exceed a paragraph.

When writing a discussion, make sure that the introduction of your discussion chapter in thesis tells the readers what the results indicate or demonstrate. You can also tell your readers what the findings suggest or whether they support a certain theory. The discussion section of a thesis should essentially be focused on the following key elements.
  • Identify patterns, correlations, and relationships of the data
  • Discuss whether the findings supported the expectations you had or your hypothesis
  • Contextualize the results within the existing theory or research
  • Consider alternative explanations while arguing for your stance
  • Explain the unexpected results and evaluate their significance
  • Do your findings agree with the previous research and what addition do they have?
  • Are your results different from those of previous studies and if so, why?
  • Do the findings challenge or support the existing theories?
  • What are the practical implications of your study?
The methodologies and research design that you use can cause limitations to your study. Unanticipated obstacles can also limit your study. Nevertheless, mention limitations only if they have direct relevance to the objectives of your research. Also, evaluate the impact of those limitations on the achievement of your research goals.

Good results and discussion thesis example can highlight a limited or small sample size as a limitation. This is a relevant limitation because it hinders the generalization of the findings.

Similarly, a discussion section can explain the problems encountered when analyzing or gathering data and how this influenced the findings. The effects of possible confounding variables that can’t be controlled should also be acknowledged in this section.

  • Recommendations In some cases, the results and discussion sample thesis can feature recommendations for further research or practical implementation. However, there are cases where recommendations are featured in the conclusion.But, you can suggest further research immediately after stating the limitations of your study and their impact. Instead of just stating that further research is necessary, provide concrete ideas for future work. Show the readers how future studies can be built on the areas that your study couldn’t address.

What to Discuss in Discussion Thesis Chapter

Many learners want to know how to write discussion chapter in Ph.D. thesis because they don’t know what to discuss. Some learners are even confused between the discussion and conclusion chapters of a thesis. But, these chapters are different and they should have varying content.

Here’s what the discussion chapter should cover:

Interpretation of the research results Comparison of the results with those of the previous studies Contributions of your research to the existing knowledge body Limitations of the study Unexpected results How the results support or refute a certain theory or findings of the previous studies

On the other hand, a conclusion should mainly restate the hypothesis and the most important results. It should also highlight the limitations and significance of the study while suggesting a future direction.

How to Make Your Discussion More Effective? Avoid These Things!

Your discussion chapter should look like an inverted pyramid. Ideally, you should start from a general perspective and then narrow down to the specifics. But, make sure that your findings are linked to the literature, theory, and practice if possible. However, many learners don’t know how to do this. This is one of the major reasons why they want to learn how to write discussion thesis section.

For even better discussions, follow these tips to help with dissertation or thesis and to make it the best it can be:

  • Restating your findings If you must remind your readers of the results of your study, use bridge sentences. For instance, tell your readers what a certain finding suggests instead of just re-stating it.
  • Repeating recommendations Do not include recommendations in both the discussion and the conclusion parts of your paper. Instead, include recommendations either in the conclusion or discussion section of your thesis.
  • Introducing new results Be careful to avoid introducing new results or information when trying to interpret a finding.
  • Over-using first person This is one of the most important things to note when learning how to write a thesis discussion. You can use the first person in your thesis. However, using it excessively will distract your readers from your major points.

Learning how to write discussion section of thesis can make all the difference in terms of the grade that you graduate with from college or university. Stylistically, this section should read like bulleted points that have been written in paragraph form. Subheadings can be used if that makes sense. And, the length of this section should also depend on the scope of the study.

Writing a compelling integrated discussion: a guide for integrated discussions in article-based theses and dissertations

  • Krystina B. Lewis , Ian D. Graham , Laura Boland and Dawn Stacey

Article-based theses and dissertations are increasingly being used in nursing and the health sciences as an alternate format to the traditional five-chapter monograph. A unique chapter in the article-based thesis is the integrated discussion, which differs in breadth and depth as compared to the discussion for a traditional thesis monograph or journal article. For many students and faculty, the integrated discussion is a challenging chapter to write, with minimal or no published guidance available. In this article, we offer a four-step approach with templates for planning and writing an integrated discussion. We also share several lessons learned with examples from published theses and dissertations. Writing an integrated discussion can be facilitated and written more efficiently by developing a clear and detailed outline of the chapter and broad discussion points prior to drafting the text, to achieve a higher-level synthesis, analysis, and interpretation of the overall significance of the thesis findings.

Introduction

An increasing number of university graduate programs in nursing and the health sciences offer the option of writing an article-based thesis or dissertation as an alternate format to the traditional five-chapter monograph ( De Jong, Moser, & Hall, 2005 ; Graves et al., 2018 ; Robinson & Dracup, 2008 ; Smaldone, Heitkemper, Jackman, Joanne Woo, & Kelson, 2019 ). This format has gained traction internationally to facilitate the earlier and more frequent publication of graduate student research for the timelier advancement of knowledge and impact on clinical practice ( Evans, Amaro, Herbert, Blossom, & Roberts, 2018 ; Maynard, Vaughn, Sarteschi, & Berglund, 2012 ; Smaldone et al., 2019 ). An article-based thesis, also known as the manuscript option, thesis-by manuscript, integrated thesis, or PhD by published works, typically includes one or more articles suitable for publication in peer-reviewed journals and bounded together with an introduction chapter and integrated discussion chapter ( Baggs, 2011 ). The integrated discussion is a unique chapter in an article-based thesis. Integrated (2020) is defined as “ many different parts [that] are closely connected and work successfully together ” (“Integrated,” 2020). The general purpose of the integrated discussion chapter is to provide an overall synthesis and demonstrate high level abstraction, analysis, and interpretation of the thesis findings. It is an opportunity to showcase the thesis’ findings, the student’s reflections about the findings, and its implications ( Smith, 2015 ).

Requirements and expectations for the integrated discussion chapter vary by institution and department. Supervising faculty within individual institutions may also have differing approaches and expectations. We found no general rules or expectations in the literature for writing an integrated discussion. An inquiry of select institutional guidance documents in various international jurisdictions revealed that academic institutions provide few details about this chapter. Descriptions focus more on the overall contribution of the integrated discussion chapter to the thesis, rather than guidance on how to write it ( Table 1 ).

Examples of institutional guidelines for the integrated discussion chapter in an article-based thesis.

Writing a compelling integrated discussion can be challenging, and there is a scarcity of resources, instructions, or published guidance for students and supervising faculty on this subject. Existing guidance is focused primarily on writing discussions for a single journal article or a traditional thesis monograph. Yet, the integrated discussion chapter differs in breadth and depth. In journal articles, a discussion usually consists of a statement of the main findings, interpretation of the results in the context of the broader literature, strengths and limitations of the study, and implications for potential users of the findings (clinicians, administrators, policy makers, and others), the discipline, and future research ( Makar, Foltz, Lendner, & Vaccaro, 2018 ). The discussion section of the traditional monograph thesis has a similar format to that of a journal article as it discusses a single study but is often more detailed. In comparison, the integrated discussion chapter of the article-based thesis provides students with a space in which to weave the results and discussion points from the individual articles comprising the thesis, elaborate on the logic and linkages between them, and convincingly argue for the unified, coherent, and original nature of their findings and contributions to the field-at-large. Smith (2015) refers to this as the golden thread. Grant (2011) refers to it as the logic of connectivity . Ultimately, it is about how the student links the key ideas from the individual papers and articulates the connectedness between them, so as to make readers understand the thesis’ broader meaning which make it accessible to a larger audience ( Smith, 2015 ).

The educational value of conceptualizing and writing an integrated discussion can be best classified at the highest level of Bloom’s revised taxonomy of educational objectives, to Create  — formerly known as Synthesis in Bloom’s original taxonomy — whereby parts are combined in novel ways to produce a coherent whole and to formulate new points of view ( Anderson & Krathwohl, 2001 ; Bloom, 1956 ). According to the taxonomy, the integrated discussion represents the pinnacle of cognitive tasks and processes by requiring higher-order thinking and critical reflections expected of graduate level students. Hence, the integrated discussion chapter provides the graduate student an opportunity to synthesize, integrate, and raise the discussion to a higher level of abstraction; allowing them to demonstrate the coherence between all articles reported in the thesis. It is often in the integrated discussion where thesis advisory committee members and examiners can assess the student’s depth of theoretical and applied knowledge of the subject matter, capacity for critical inquiry, and judge the overall value of the student’s conclusions and contributions to the substantive area of study ( Gould, 2016 ). Specifically in nursing, this higher-level thinking can be articulated by discussing how the knowledge generated advances nursing practice, education and research, and how it contributes to the delivery of high quality health care, and improved health and health system outcomes ( Institute of Medicine [US] Committee on the Robert Wood Johnson Foundation Initiative on the Future of Nursing, 2011 ). Yet, with little guidance available on how to think about and write an integrated discussion, graduate students may miss the opportunity to engage in this higher-order thinking and critical reflections.

In this paper, we offer a practical four-step approach with templates for writing an integrated discussion for article-based theses. KBL initially developed the steps and templates as she conceptualized and wrote her integrated discussion for her PhD dissertation. The steps and templates were refined as a result of (a) her own integrated discussion writing process; (b) discussion with her thesis supervisor and thesis advisory committee members; and, (c) feedback from several graduate students who have used it successfully. As recent doctoral graduates and faculty supervisors, we are sharing this approach and our lessons learned with examples from published theses and dissertations.

Writing an integrated discussion chapter

Step 1: outlining the integrated discussion chapter.

To begin, we propose drafting an outline for the integrated discussion chapter with six major sections ( Table 2 ). First, provide an opening paragraph introducing the information to be presented in the chapter. Second, present a summary of the overall purpose of the thesis as a unified piece of work and a brief summary of each individual article prepared for publication. Each article summary should include the study aim, study design, and key results. Keep in mind that by the time supervisors, thesis advisory committee members, and examiners read the integrated discussion chapter, they have probably just finished reading the previous chapters and articles, so there is no need to repeat information in detail. Rather, the purpose of this section is to refresh the readers’ focus and to begin demonstrating how the articles logically link to each other. Third, outline the main points of the integrated discussion as clearly and concisely as possible (see Step 2 and 3 for more details). Fourth, discuss the strengths and limitations of the thesis, as a whole, if applicable. Typically, strengths and limitations are only presented at the individual article level, but if there are broader strengths or limitations that apply to the thesis, they can be discussed in this chapter. Fifth, discuss the implications of the thesis for the specific discipline (e.g., nursing, medicine, population health, epidemiology, rehabilitation) in terms of the findings’ applicability to practice, education, leadership, and/or policy. Sixth, describe implications for future research. Finally, this chapter should end with a strong, clear, and logical conclusion summarizing the entire work across all elements of the thesis. The conclusions should clearly state the original contribution(s) to the advancement of knowledge and overall significance for the field at-large.

Step 2. Mapping individual articles’ findings to inform the integrated discussion

The next step is to draft the main integrated discussion points. Using Template I, capture the main discussion points from each individual article ( Table 3 ). If there is only one article in the thesis, these can be generated from the literature review, guiding theoretical framework, and/or chosen methodology. This exercise is intended to facilitate the student’s thinking about how to build convincing overarching discussion points and explore the key messages they want readers to come away with after reading the thesis.

Template I to summarize individual article discussion points to identify overarching discussion points.

a If there is only one article in the thesis, additional discussion points/contributions/implications can come from the literature review, guiding theoretical framework, and/or chosen methodology. b Whether these implications are included in the individual article or not, this explicitly offers a starting point to think of the implications arising from individual articles.

The last row in this template is reserved for listing the actual and potential disciplinary implications arising from each article, which may address any of the following domains: practice, education, leadership, policy and/or research. Depending on journal requirements, these implications may be directly discussed in the individual articles. If not, this section offers the student a starting point for thinking about the disciplinary implications arising from their thesis as a whole.

Completing Template I as individual articles are finalized, and sharing it with a faculty supervisor or thesis advisory committee can facilitate discussion about the evolving integrated discussion points. It can also facilitate requisite critical thinking and reflection necessary for linking findings across the individual articles.

Step 3. Drafting the main integrated discussion points

Consider the discussion points and disciplinary implications across all individual articles of the thesis to identify commonalities or differences;

Draft main integrated discussion points, logically connecting the individual articles;

Identify findings from, ideally, two individual articles that support (or refute) the proposed main integrated discussion points (aiming for evidence from two articles helps achieve a higher level integrated discussion); and

Identify and classify theoretical and empirical literature relevant to the main integrated discussion points. Select regional, national, and international empirical studies, theoretical works, clinical practice guidelines, technical reports, and/or policy documents; highlight what the thesis adds to the field (of knowledge) and how it will enhance understanding of the subject.

Template II to build the main integrated discussion points from the individual articles and summarize implications.

a If there is only one article in the thesis, the supporting contributions/arguments can come from the literature review, guiding theoretical framework, and/or chosen methodology. b Broader literature can include empirical studies, theoretical works, practice guidelines, technical reports, and/or policy documents. c List the disciplinary implications identified across all articles. This explicitly offers a starting point to think of the disciplinary implications arising across the individual articles’ findings and discussion points.

This exercise is intended to help organize the content of the integrated discussion early in the writing process. We recommend sharing the evolving Templates I and II with the faculty supervisor or thesis advisory committee and use it as a tool for discussion before writing the integrated discussion chapter. As supervisors (DS, IDG), we also initiate Template I in discussion with our graduate students – often using a blank piece of paper. This reflective exercise may save time in the long run, as it facilitates staying focused on the key points and avoids repeating elements of the discussions within the individual papers. The more detailed the completed templates, the more content is available to transform into text.

Step 4. Writing the integrated discussion chapter

The final step is to turn the planned outline (Step 1) and the drafted main integrated discussion points (Step 3) into narrative prose. To remain focused, start by adding subheadings from the outline and lower level subheadings for each of the main integrated discussion points. A compelling integrated discussion is often preceded by multiple revisions. It should not be written when rushing to meet the thesis submission deadline as writing this chapter requires considerable reflection and introspection. For these reasons, we remind students that the integrated discussion is the last chapter their examiners will read, and it will leave a lasting impression. Getting this chapter right allows the student to demonstrate their mastery of the totality of their thesis work and sets the stage for the examination. In our experience, when an integrated discussion is well-written, the examiners’ comments indicate that the integrated discussion chapter tied all elements of the thesis together and helped them understand the thesis in its entirety.

Lessons learned

When applying this approach for writing our own integrated discussions, or when guiding graduate students through the process, we have learned several lessons. To exemplify these lessons, we offer examples of published theses and dissertations in nursing and other health professions.

Lesson 1. Use stepwise approach with templates to plan and structure the chapter

Using the attached templates and proposed stepwise approach to structure the writing process reduces the inclination to simply repeat the discussion points found in the individual articles. The templates may also help graduate students overcome procrastination resulting from not knowing where to start with the integrated discussion. Further, Templates I and II may be used to guide discussions between graduate student and faculty supervisor, allowing for progress to be monitored prior to writing. Another advantage to doing this early is that some supervisors are less familiar with the article-based thesis format and may have little experience guiding their students in writing the integrated discussion. As such, using the template to walk through this process may be helpful for both parties.

Lesson 2. Think ahead

Avoid delaying until all the individual thesis articles are written before thinking about the integrated discussion. We recommend filling out the templates as individual articles are completed. When analyzing the results for individual articles and thinking about the discussion sections for these, we often identified relevant discussion points that were too broad for the articles. Keeping a log of discussions with faculty supervisors and thesis advisory committee members throughout the thesis writing process, and keeping record of personal reflections that were beyond the scope of individual articles, may help gather ideas early. For example, when first considering her integrated discussion, Hoefel (2019) chose the Walker and Avant (2011) theory testing approach to validate the decisional needs concept and test the main hypothesis of the Ottawa Decision Support Framework ( O’Connor et al., 1998 ). For her thesis, Hoefel (2019) wrote two articles based upon this framework. Her first was a systematic review article on decisional needs of people making health decisions and the second was a sub-analysis of a systematic review on patient decision aids. Hence, evidence from these articles contributed to the higher level discussion about validating the concepts and testing the hypotheses in the framework.

Lesson 3. Dedicate sufficient time

Dedicating sufficient time to writing the integrated discussion is important. For many students, the integrated discussion is a challenging chapter to write. It calls for a different style of writing than that which is required for individual research study articles. It requires conveying abstract and conceptual ideas to generate broader insights. Prior to developing and using these templates, our experience with many students has been that it can take many months of re-writing the integrated discussion chapter for it to adequately reflect the breadth and depth of the student’s thesis work and its vital contribution to the field. We have found that our stepwise approach involves more careful planning and conceptualizing of the integrated discussion prior to drafting the chapter, and therefore results in a more efficient writing and editing process.

Lesson 4. Consider theoretical and methodological implications

Theoretical and methodological implications may be considered as integrated discussion points. A student may choose to closely examine their selected theoretical perspective in light of their thesis findings. For example, in Lewis’ (2018) integrated discussion, she provided a discourse on the use of complementary theoretical frameworks across individual studies: the Ottawa Decision Support Framework ( O’Connor et al., 1998 ) and Normalization Process Theory ( May et al., 2009 ). This provided a link between intervention development and implementation planning, proposing a novel theory-informed approach for the development of decision support interventions ( Lewis, 2018 ). Likewise, methodological implications may be discussed in cases where a student’s thesis advances methods, or to discuss the influence of chosen methodology on key findings where similar research questions are answered using distinct study designs. Wu’s (2014) integrated discussion focused on the methods used for conducting a survey for data collection. He used a set of reminders, with the last reminder being a courier package and return envelope. He then discussed how testing this reminder strategy in his thesis study contributed to survey design methods.

Lesson 5. An integrated discussion is feasible with one article

In cases where there is only one article comprising an article-based thesis, key findings from a more detailed literature review, a theoretical framework guiding the entire research project, or chosen methodology can provide the additional linkages to build the main integrated discussion points. For instance, in her Master of Nursing thesis integrated discussion, Demery Varin (2018) compared and contrasted her secondary analysis findings on the predictors of nurses’ research use in long-term care settings (as reported in one published article) with her review of the literature on the individual and contextual factors to nurses’ research use in all settings.

Lesson 6. Integrated discussions are publishable

The integrated discussion (or elements of it) may be publishable in its own right. When written well, the integrated discussion often results in an important academic contribution to the body of knowledge. Some graduate students have used the integrated discussion as the basis for a commentary paper or an updated theoretical framework paper. In her integrated discussion chapter of her doctoral thesis, Jull (2014) described the development of a collaborative framework for community-research partnerships co-produced by First Nations, Inuit, and Metis women’s community members and researchers. This framework was based on her findings and experience conducting the studies comprising her thesis. Jull et al. (2018) subsequently published a paper based on her integrated discussion.

Lesson 7. Integrated discussions can lay the foundation for subsequent research

Many students who are completing a Master’s or PhD thesis also intend to pursue further research. A well thought out and articulated integrated discussion can inform subsequent research projects, grant proposals, or programs of research. For example, Boland (2018) drew from her PhD integrated discussion to identify evidence-practice gaps and potential solutions in pediatric shared decision-making, which she used to underpin a successful Canadian Institutes of Health Research post-doctoral fellowship and guide the establishment of her research program.

In this paper, we propose an approach to writing an integrated discussion chapter for an article-based thesis. Our advice provided in this paper is intended to position graduate students to adequately plan and produce a unified, coherent, and higher-level synthesis of the articles comprising their thesis. Challenges in writing an integrated discussion include avoiding repetition of discussion points already included within the individual articles comprising the thesis and achieving a higher-level discussion to integrate findings across the individual articles. Writing an integrated discussion can be facilitated by developing a clear and detailed outline of the chapter and, in particular, by identifying broader, more overarching points of discussion, than those presented within the individual articles. We encourage graduate students, faculty supervisors and thesis advisory committees to use the templates provided and share their experiences.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

  • master the academic foundational skills (research, writing, ability to navigate different modalities)
  • time-management skills and the ability to focus on reading and writing
  • determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

Know How to Structure Your PhD Thesis

  • 4 minute read

Table of Contents

In your academic career, few projects are more important than your PhD thesis. Unfortunately, many university professors and advisors assume that their students know how to structure a PhD. Books have literally been written on the subject, but there’s no need to read a book in order to know about PhD thesis paper format and structure. With that said, however, it’s important to understand that your PhD thesis format requirement may not be the same as another student’s. The bottom line is that how to structure a PhD thesis often depends on your university and department guidelines.

But, let’s take a look at a general PhD thesis format. We’ll look at the main sections, and how to connect them to each other. We’ll also examine different hints and tips for each of the sections. As you read through this toolkit, compare it to published PhD theses in your area of study to see how a real-life example looks.

Main Sections of a PhD Thesis

In almost every PhD thesis or dissertation, there are standard sections. Of course, some of these may differ, depending on your university or department requirements, as well as your topic of study, but this will give you a good idea of the basic components of a PhD thesis format.

  • Abstract : The abstract is a brief summary that quickly outlines your research, touches on each of the main sections of your thesis, and clearly outlines your contribution to the field by way of your PhD thesis. Even though the abstract is very short, similar to what you’ve seen in published research articles, its impact shouldn’t be underestimated. The abstract is there to answer the most important question to the reviewer. “Why is this important?”
  • Introduction : In this section, you help the reviewer understand your entire dissertation, including what your paper is about, why it’s important to the field, a brief description of your methodology, and how your research and the thesis are laid out. Think of your introduction as an expansion of your abstract.
  • Literature Review : Within the literature review, you are making a case for your new research by telling the story of the work that’s already been done. You’ll cover a bit about the history of the topic at hand, and how your study fits into the present and future.
  • Theory Framework : Here, you explain assumptions related to your study. Here you’re explaining to the review what theoretical concepts you might have used in your research, how it relates to existing knowledge and ideas.
  • Methods : This section of a PhD thesis is typically the most detailed and descriptive, depending of course on your research design. Here you’ll discuss the specific techniques you used to get the information you were looking for, in addition to how those methods are relevant and appropriate, as well as how you specifically used each method described.
  • Results : Here you present your empirical findings. This section is sometimes also called the “empiracles” chapter. This section is usually pretty straightforward and technical, and full of details. Don’t shortcut this chapter.
  • Discussion : This can be a tricky chapter, because it’s where you want to show the reviewer that you know what you’re talking about. You need to speak as a PhD versus a student. The discussion chapter is similar to the empirical/results chapter, but you’re building on those results to push the new information that you learned, prior to making your conclusion.
  • Conclusion : Here, you take a step back and reflect on what your original goals and intentions for the research were. You’ll outline them in context of your new findings and expertise.

Tips for your PhD Thesis Format

As you put together your PhD thesis, it’s easy to get a little overwhelmed. Here are some tips that might keep you on track.

  • Don’t try to write your PhD as a first-draft. Every great masterwork has typically been edited, and edited, and…edited.
  • Work with your thesis supervisor to plan the structure and format of your PhD thesis. Be prepared to rewrite each section, as you work out rough drafts. Don’t get discouraged by this process. It’s typical.
  • Make your writing interesting. Academic writing has a reputation of being very dry.
  • You don’t have to necessarily work on the chapters and sections outlined above in chronological order. Work on each section as things come up, and while your work on that section is relevant to what you’re doing.
  • Don’t rush things. Write a first draft, and leave it for a few days, so you can come back to it with a more critical take. Look at it objectively and carefully grammatical errors, clarity, logic and flow.
  • Know what style your references need to be in, and utilize tools out there to organize them in the required format.
  • It’s easier to accidentally plagiarize than you think. Make sure you’re referencing appropriately, and check your document for inadvertent plagiarism throughout your writing process.

Last impressions count – writing your PhD thesis conclusion

Feb 12, 2019

write a phd thesis conclusion

Picture this: your examiner has just spent a week reading your thesis (yes – it takes that long!). They’ve understood your aims and objectives, like your methodology, think you applied your theory well and found your results fascinating.

Then they get to the conclusion and see that it is badly written. It seems unclear and hasn’t answered the research questions. The contribution is left hanging. It’s making grandiose claims that aren’t backed up in the empirics. The report that they subsequently write for your viva questions whether the research is actually complete.

Awful, right? Well, it happens a lot. The conclusion is the last thing the examiner reads and has a lasting impact on how they see the whole thesis.

That means: last impressions count.

In this guide,  I explain to you in clear and simple terms how to write a superstar PhD thesis conclusion. One that really impresses your examiner and gives your thesis the send-off it deserves.

There are lots of guides out there that explain how to write a PhD thesis conclusion, but few that explain how to write outstanding conclusions.

Keep reading.

The purpose of a conclusion

You can see from your PhD Writing Template that a PhD conclusion should achieve six objectives:

Answer the research questions Show how you have addressed your aims and objectives Explain the significance and implications of your findings Explain the contribution the study makes Explain the limitations of the study Lay out questions for further research

These are the basics and you probably know them already.

The problem is that most guides I’ve found online to writing PhD thesis conclusions seem to stop at these six points.

That’s fine, but if you want to write a superstar conclusion – and you do, because last impression counts remember – you need to consider a whole bunch of other things.

Keep reading, I’ll show you how.

How to write a superstar conclusion

Think of reading a PhD thesis being like a journey.

At the beginning, you – the author – are talking in speculative terms, particularly during your literature and theory work. You are saying ‘what if’ and postulating about what might be out there once you enter the field.

You talk in terms of hypotheses and potentials. The tone is one of: ‘perhaps things might be behaving in a certain way, so let’s get out in the field and see whether they do or not’.

As you go through the empirical chapters you begin to introduce a bit more certainty into your discussion. You start to change from ‘what if’ to ‘here is what’s happening’.

But – and this is the important bit – by the time you have reached the conclusion you have eliminated all uncertainty.

As a result, you are now the expert in your field. You have scoped out the potential, jumped into the field and achieved your objectives.

There are two things to consider if you want to write a superstar conclusion.

1. Own your research

So, in the conclusion, start talking like an expert. Showcase your expertise and show your examiner that you are worthy of being called Doctor. If you don’t execute your conclusion properly and leave things unfinished, the examiner is questioning your suitability and is going to recommend that you work on your thesis for another few months.

But wait, what do I mean by ‘unfinished’?

Well, answering the six questions above is imperative. But, most importantly, you need to really drive home the contribution that the thesis has made . Regardless of whether you can see it or not, your thesis contributes something to the field. It might be a new methodology, a new application of theory onto an existing body of data or sample, or a contradiction of established ways of thinking. Whatever it is, you need to shout about it. Loudly. Like an expert.

If you hesitate and remain vague, the examiner will see this . Sure, you might think that the research could have been better. Sure, you messed up that one experiment. Sure, you aimed to find one thing but ended up finding another. But focus on those shortcomings later, after you have told the reader about all the fantastic contributions you have made (however small – and in fact, they will be small. Don’t try to over-generalise your contribution ) and after you have shown how, you would have fulfilled the research aims and objectives.

While you’re doing it, own the literature . Relate your findings back to particular studies and don’t be afraid to say what studies your new findings seems to contradict or which it seems to invalidate. That’s what exerting your (new) authority is all about.

A conclusion that fails to relate the findings to the literature is an incomplete conclusion. You spent pages and pages neatly carving out a gap in the literature; the least you can do is show how your research fills that gap.

2. See the thesis, not the detail

A superstar conclusion is one that doesn’t get weighed down in detail. It talks to the thesis, not the detail. The time for detail is over. Now you take a step back and look at the entire project.

Each chapter is a piece of the puzzle and only when they are all slotted together do you have an entire thesis. That means that a great conclusion is one that shows that the thesis is bigger than the sum of its individual chapters.

The conclusion is not the time to get lost in words and talk in lengthy detail about particular theoretical, empirical or methodological issues; you’ve had the previous 200 pages or so to do that. Instead, it’s the time to clearly and concisely – but still critically – explain your thesis and its significance.

So, rather than get bogged down in detail, your job is to reflect back on your original aims and intentions and discuss them in terms of your findings and new expertise.

It also means summarising your thesis in a way that is free of unnecessary detail and is easy to understand.

Three things not to do in a conclusion

1. don’t repeat yourself.

Somewhere in your conclusion, you need to have an executive summary of your entire thesis. Our PhD writing template can help with this, as it forces you to write a synopsis of each chapter which you can add together for a summary of the thesis.

Note, though, that there’s a difference between summarising your thesis and repeating huge tracts of it. If you have done your job properly in the empirical and discussion chapters, the reader will be familiar with your findings. There’s no need to repeat them in the conclusion. It’ll bore the pants off your examiner if they have to read them again.

A quick summary or recap of the findings is sufficient, not a lengthy restatement. The same is true with your theory framework or literature review. Recap, don’t repeat.

2. Don’t introduce new text or material

The job of the conclusion then is to summarise and recap, not to introduce new material. If you feel the need to include new empirical material or new literature here, don’t. It needs to go elsewhere.

The conclusion will certainly talk back to your literature review or empirical data, in the sense that it will seek to fulfil certain objectives and address a gap in the literature. The point is that you need to state your objectives and discuss the gap in the literature earlier in the thesis. You use the conclusion to relate the empirical findings to those objectives and to that gap. The literature review and theory framework lay out the objectives and aims of the research, whereas the conclusion discusses how you have met those objectives and aims. It will neither lay out new objectives or aims (using new literature), nor will it do the job of fulfilling those aims (by presenting new empirical data). It will merely explain in clear terms how you have done those things elsewhere in the text.

3. Don’t pretend that your thesis does more than it actually does

Remember earlier when we discussed not owning your research and speaking as an authority? One way to fail at this is to over-generalise or to pretend that your thesis does more than it actually does.

There is no shame in focusing in on a very specific contribution . It’s unlikely that your PhD thesis is going to completely revolutionise your field, so don’t claim that it has. Instead, refer back to your literature review and relate it to other discussions and the gaps that you identified. This isn’t to suggest that your study can’t impact the broader field; if you think your study (which, lets face it, is going to be limited, given the constraints of doctoral research) has the potential to revolutionise the field you should lay these out as questions for future research. Or, perhaps your thesis has policy implications – don’t be afraid to list them, but don’t be overconfident in your appraisal.

Don’t forget to discuss the implications or your thesis and the directions for future research. No PhD thesis is perfect and you should acknowledge what your thesis didn’t do as much as what it could have. This doesn’t stop with a discussion on the epistemological, ontological or methodological limitations of the study, but extends to your own personal limitations. Did you run out of time? Did you struggle to recruit participants because of language barriers? Or maybe you didn’t have the budget to conduct the study you wanted to? These kinds of personal reflections are important, as they show humility and that you are aware of avenues for growth.

A conclusion that fails to explain the contribution, that fails to recap and that fails to focus on the entire thesis rather than the detail will leave the reader unsatisfied.

The conclusion needs to wrap up the research.   It needs to clearly state the answers to the research questions and lay out in clear, undisputed terms the contribution that you are making. Fail to do this and you’ll be left trying to convince your examiner that the study is complete when it comes to your viva.

Do it well, and the examiner will already think you’re worthy of the title Doctor before your viva has even begun.
