How to Write the Rationale of the Study in Research (Examples)

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper. 

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

How to write a rationale for a research paper , how do you justify the need for a research study.

• Study Rationale Example: Where Does It Go In Your Paper?

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air. 

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach. 

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted. 

• Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
• Once research has been conducted : After the study is completed, the rationale is presented in a research article or  PhD dissertation  to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

• A summary of conclusions from your review of the relevant literature
• What is currently unknown (gaps in knowledge)
• Inconclusive or contested results  from previous studies on the same or similar topic
• The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are. 

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

• Did earlier studies try but failed to measure/identify a specific phenomenon?
• Was earlier research based on incorrect conceptualizations of variables?
• Were earlier studies based on questionable operationalizations of key concepts?
• Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

• Have recent changes in the studied problem made previous studies irrelevant?
• Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

• Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) . 

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .  

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A  dissertation or thesis  usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

How to Write the Rationale for a Research Paper

• Research Process
• Peer Review

A research rationale answers the big SO WHAT? that every adviser, peer reviewer, and editor has in mind when they critique your work. A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at the purpose of a research rationale, its components and key characteristics, and how to create an effective research rationale.

Updated on September 19, 2022

The rationale for your research is the reason why you decided to conduct the study in the first place. The motivation for asking the question. The knowledge gap. This is often the most significant part of your publication. It justifies the study's purpose, novelty, and significance for science or society. It's a critical part of standard research articles as well as funding proposals.

Essentially, the research rationale answers the big SO WHAT? that every (good) adviser, peer reviewer, and editor has in mind when they critique your work.

A compelling research rationale increases the chances of your paper being published or your grant proposal being funded. In this article, we look at:

• the purpose of a research rationale
• its components and key characteristics
• how to create an effective research rationale

What is a research rationale?

Think of a research rationale as a set of reasons that explain why a study is necessary and important based on its background. It's also known as the justification of the study, rationale, or thesis statement.

Essentially, you want to convince your reader that you're not reciting what other people have already said and that your opinion hasn't appeared out of thin air. You've done the background reading and identified a knowledge gap that this rationale now explains.

A research rationale is usually written toward the end of the introduction. You'll see this section clearly in high-impact-factor international journals like Nature and Science. At the end of the introduction there's always a phrase that begins with something like, "here we show..." or "in this paper we show..." This text is part of a logical sequence of information, typically (but not necessarily) provided in this order:

Here's an example from a study by Cataldo et al. (2021) on the impact of social media on teenagers' lives.

Note how the research background, gap, rationale, and objectives logically blend into each other.

The authors chose to put the research aims before the rationale. This is not a problem though. They still achieve a logical sequence. This helps the reader follow their thinking and convinces them about their research's foundation.

Elements of a research rationale

We saw that the research rationale follows logically from the research background and literature review/observation and leads into your study's aims and objectives.

This might sound somewhat abstract. A helpful way to formulate a research rationale is to answer the question, “Why is this study necessary and important?”

Generally, that something has never been done before should not be your only motivation. Use it only If you can give the reader valid evidence why we should learn more about this specific phenomenon.

A well-written introduction covers three key elements:

• What's the background to the research?
• What has been done before (information relevant to this particular study, but NOT a literature review)?
• Research rationale

Now, let's see how you might answer the question.

1. This study complements scientific knowledge and understanding

Discuss the shortcomings of previous studies and explain how'll correct them. Your short review can identify:

• Methodological limitations . The methodology (research design, research approach or sampling) employed in previous works is somewhat flawed.

Example : Here , the authors claim that previous studies have failed to explore the role of apathy “as a predictor of functional decline in healthy older adults” (Burhan et al., 2021). At the same time, we know a lot about other age-related neuropsychiatric disorders, like depression.

Their study is necessary, then, “to increase our understanding of the cognitive, clinical, and neural correlates of apathy and deconstruct its underlying mechanisms.” (Burhan et al., 2021).

• Contextual limitations . External factors have changed and this has minimized or removed the relevance of previous research.

Example : You want to do an empirical study to evaluate the effects of the COVID-19 pandemic on the number of tourists visiting Sicily. Previous studies might have measured tourism determinants in Sicily, but they preceded COVID-19.

• Conceptual limitations . Previous studies are too bound to a specific ideology or a theoretical framework.

Example : The work of English novelist E. M. Forster has been extensively researched for its social, political, and aesthetic dimensions. After the 1990s, younger scholars wanted to read his novels as an example of gay fiction. They justified the need to do so based on previous studies' reliance on homophobic ideology.

This kind of rationale is most common in basic/theoretical research.

2. This study can help solve a specific problem

Here, you base your rationale on a process that has a problem or is not satisfactory.

For example, patients complain about low-quality hospital care on weekends (staff shortages, inadequate attention, etc.). No one has looked into this (there is a lack of data). So, you explore if the reported problems are true and what can be done to address them. This is a knowledge gap.

Or you set out to explore a specific practice. You might want to study the pros and cons of several entry strategies into the Japanese food market.

It's vital to explain the problem in detail and stress the practical benefits of its solution. In the first example, the practical implications are recommendations to improve healthcare provision.

In the second example, the impact of your research is to inform the decision-making of businesses wanting to enter the Japanese food market.

This kind of rationale is more common in applied/practical research.

3. You're the best person to conduct this study

It's a bonus if you can show that you're uniquely positioned to deliver this study, especially if you're writing a funding proposal .

For an anthropologist wanting to explore gender norms in Ethiopia, this could be that they speak Amharic (Ethiopia's official language) and have already lived in the country for a few years (ethnographic experience).

Or if you want to conduct an interdisciplinary research project, consider partnering up with collaborators whose expertise complements your own. Scientists from different fields might bring different skills and a fresh perspective or have access to the latest tech and equipment. Teaming up with reputable collaborators justifies the need for a study by increasing its credibility and likely impact.

When is the research rationale written?

You can write your research rationale before, or after, conducting the study.

In the first case, when you might have a new research idea, and you're applying for funding to implement it.

Or you're preparing a call for papers for a journal special issue or a conference. Here , for instance, the authors seek to collect studies on the impact of apathy on age-related neuropsychiatric disorders.

In the second case, you have completed the study and are writing a research paper for publication. Looking back, you explain why you did the study in question and how it worked out.

Although the research rationale is part of the introduction, it's best to write it at the end. Stand back from your study and look at it in the big picture. At this point, it's easier to convince your reader why your study was both necessary and important.

How long should a research rationale be?

The length of the research rationale is not fixed. Ideally, this will be determined by the guidelines (of your journal, sponsor etc.).

The prestigious journal Nature , for instance, calls for articles to be no more than 6 or 8 pages, depending on the content. The introduction should be around 200 words, and, as mentioned, two to three sentences serve as a brief account of the background and rationale of the study, and come at the end of the introduction.

If you're not provided guidelines, consider these factors:

• Research document : In a thesis or book-length study, the research rationale will be longer than in a journal article. For example, the background and rationale of this book exploring the collective memory of World War I cover more than ten pages.
• Research question : Research into a new sub-field may call for a longer or more detailed justification than a study that plugs a gap in literature.

Which verb tenses to use in the research rationale?

It's best to use the present tense. Though in a research proposal, the research rationale is likely written in the future tense, as you're describing the intended or expected outcomes of the research project (the gaps it will fill, the problems it will solve).

Rationale for the Study

It is important for you to be able to explain the importance of the research you are conducting by providing valid arguments. Rationale for the study, also referred to as justification for the study, is reason why you have conducted your study in the first place. This part in your paper needs to explain uniqueness and importance of your research. Rationale for the study needs to be specific and ideally, it should relate to the following points:

1. The research needs to contribute to the elimination of a gap in the literature. Elimination of gap in the present literature is one of the compulsory requirements for your study. In other words, you don’t need to ‘re-invent the wheel’ and your research aims and objectives need to focus on new topics. For example, you can choose to conduct an empirical study to assess the implications of COVID-19 pandemic on the numbers of tourists visitors in your city. This might be previously undressed topic, taking into account that COVID-19 pandemic is a relatively recent phenomenon.

Alternatively, if you cannot find a new topic to research, you can attempt to offer fresh perspectives on existing management, business or economic issues. For example, while thousands of studies have been previously conducted to study various aspects of leadership, this topic as far from being exhausted as a research area. Specifically, new studies can be conducted in the area of leadership to analyze the impacts of new communication mediums such as TikTok, and other social networking sites on leadership practices.

You can also discuss the shortcomings of previous works devoted to your research area. Shortcomings in previous studies can be divided into three groups:

a) Methodological limitations . Methodology employed in previous study may be flawed in terms of research design, research approach or sampling.

b) Contextual limitations . Relevance of previous works may be non-existent for the present because external factors have changed.

c) Conceptual limitations . Previous studies may be unjustifiably bound up to a particular model or an ideology.

While discussing the shortcomings of previous studies you should explain how you are going to correct them. This principle is true to almost all areas in business studies i.e. gaps or shortcomings in the literature can be found in relation to almost all areas of business and economics.

2. The research can be conducted to solve a specific problem. It helps if you can explain why you are the right person and in the right position to solve the problem. You have to explain the essence of the problem in a detailed manner and highlight practical benefits associated with the solution of the problem. Suppose, your dissertation topic is “a study into advantages and disadvantages of various entry strategies into Chinese market”. In this case, you can say that practical implications of your research relates to assisting businesses aiming to enter Chinese market to do more informed decision making.

Alternatively, if your research is devoted to the analysis of impacts of CSR programs and initiatives on brand image, practical contributions of your study would relate to contributing to the level of effectiveness of CSR programs of businesses.

Additional examples of studies that can assist to address specific practical problems may include the following:

• A study into the reasons of high employee turnover at Hanson Brick
• A critical analysis of employee motivation problems at Esporta, Finchley Road, London
• A research into effective succession planning at Microsoft
• A study into major differences between private and public primary education in the USA and implications of these differences on the quality of education

However, it is important to note that it is not an obligatory for a dissertation   to be associated with the solution of a specific problem. Dissertations can be purely theory-based as well. Examples of such studies include the following:

• Born or bred: revising The Great Man theory of leadership in the 21 st century
• A critical analysis of the relevance of McClelland’s Achievement theory to the US information technology industry
• Neoliberalism as a major reason behind the emergence of the global financial and economic crisis of 2007-2009
• Analysis of Lewin’s Model of Change and its relevance to pharmaceutical sector of France

3. Your study has to contribute to the level of professional development of the researcher . That is you. You have to explain in a detailed manner in what ways your research contributes to the achievement of your long-term career aspirations.

For example, you have selected a research topic of “ A critical analysis of the relevance of McClelland’s Achievement theory in the US information technology industry ”.  You may state that you associate your career aspirations with becoming an IT executive in the US, and accordingly, in-depth knowledge of employee motivation in this industry is going to contribute your chances of success in your chosen career path.

Therefore, you are in a better position if you have already identified your career objectives, so that during the research process you can get detailed knowledge about various aspects of your chosen industry.

My e-book, The Ultimate Guide to Writing a Dissertation in Business Studies: a step by step assistance offers practical assistance to complete a dissertation with minimum or no stress. The e-book covers all stages of writing a dissertation starting from the selection to the research area to submitting the completed version of the work within the deadline.

Setting Rationale in Research: Cracking the code for excelling at research

Knowledge and curiosity lays the foundation of scientific progress. The quest for knowledge has always been a timeless endeavor. Scholars seek reasons to explain the phenomena they observe, paving way for development of research. Every investigation should offer clarity and a well-defined rationale in research is a cornerstone upon which the entire study can be built.

Research rationale is the heartbeat of every academic pursuit as it guides the researchers to unlock the untouched areas of their field. Additionally, it illuminates the gaps in the existing knowledge, and identifies the potential contributions that the study aims to make.

Table of Contents

What Is Research Rationale and When Is It Written

Research rationale is the “why” behind every academic research. It not only frames the study but also outlines its objectives , questions, and expected outcomes. Additionally, it helps to identify the potential limitations of the study . It serves as a lighthouse for researchers that guides through data collection and analysis, ensuring their efforts remain focused and purposeful. Typically, a rationale is written at the beginning of the research proposal or research paper . It is an essential component of the introduction section and provides the foundation for the entire study. Furthermore, it provides a clear understanding of the purpose and significance of the research to the readers before delving into the specific details of the study. In some cases, the rationale is written before the methodology, data analysis, and other sections. Also, it serves as the justification for the research, and how it contributes to the field. Defining a research rationale can help a researcher in following ways:

1. Justification of a Research Problem

• Research rationale helps to understand the essence of a research problem.
• It designs the right approach to solve a problem. This aspect is particularly important for applied research, where the outcomes can have real-world relevance and impact.
• Also, it explains why the study is worth conducting and why resources should be allocated to pursue it.
• Additionally, it guides a researcher to highlight the benefits and implications of a strategy.

2. Elimination of Literature Gap

• Research rationale helps to ideate new topics which are less addressed.
• Additionally, it offers fresh perspectives on existing research and discusses the shortcomings in previous studies.
• It shows that your study aims to contribute to filling these gaps and advancing the field’s understanding.

3. Originality and Novelty

• The rationale highlights the unique aspects of your research and how it differs from previous studies.
• Furthermore, it explains why your research adds something new to the field and how it expands upon existing knowledge.
• It highlights how your findings might contribute to a better understanding of a particular issue or problem and potentially lead to positive changes.
• Besides these benefits, it provides a personal motivation to the researchers. In some cases, researchers might have personal experiences or interests that drive their desire to investigate a particular topic.

4. An Increase in Chances of Funding

• It is essential to convince funding agencies , supervisors, or reviewers, that a research is worth pursuing.
• Therefore, a good rationale can get your research approved for funding and increases your chances of getting published in journals; as it addresses the potential knowledge gap in existing research.

Overall, research rationale is essential for providing a clear and convincing argument for the value and importance of your research study, setting the stage for the rest of the research proposal or manuscript. Furthermore, it helps establish the context for your work and enables others to understand the purpose and potential impact of your research.

5 Key Elements of a Research Rationale

Research rationale must include certain components which make it more impactful. Here are the key elements of a research rationale:

By incorporating these elements, you provide a strong and convincing case for the legitimacy of your research, which is essential for gaining support and approval from academic institutions, funding agencies, or other stakeholders.

How to Write a Rationale in Research

Writing a rationale requires careful consideration of the reasons for conducting the study. It is usually written in the present tense.

Here are some steps to guide you through the process of writing a research rationale:

After writing the initial draft, it is essential to review and revise the research rationale to ensure that it effectively communicates the purpose of your research. The research rationale should be persuasive and compelling, convincing readers that your study is worthwhile and deserves their attention.

How Long Should a Research Rationale be?

Although there is no pre-defined length for a rationale in research, its length may vary depending on the specific requirements of the research project. It also depends on the academic institution or organization, and the guidelines set by the research advisor or funding agency. In general, a research rationale is usually a concise and focused document.

Typically, it ranges from a few paragraphs to a few pages, but it is usually recommended to keep it as crisp as possible while ensuring all the essential elements are adequately covered. The length of a research rationale can be roughly as follows:

1. For Research Proposal:

A. Around 1 to 3 pages

B. Ensure clear and comprehensive explanation of the research question, its significance, literature review , and methodological approach.

2. Thesis or Dissertation:

A. Around 3 to 5 pages

B. Ensure an extensive coverage of the literature review, theoretical framework, and research objectives to provide a robust justification for the study.

3. Journal Article:

A. Usually concise. Ranges from few paragraphs to one page

B. The research rationale is typically included as part of the introduction section

However, remember that the quality and content of the research rationale are more important than its length. The reasons for conducting the research should be well-structured, clear, and persuasive when presented. Always adhere to the specific institution or publication guidelines.

Example of a Research Rationale

In conclusion, the research rationale serves as the cornerstone of a well-designed and successful research project. It ensures that research efforts are focused, meaningful, and ethically sound. Additionally, it provides a comprehensive and logical justification for embarking on a specific investigation. Therefore, by identifying research gaps, defining clear objectives, emphasizing significance, explaining the chosen methodology, addressing ethical considerations, and recognizing potential limitations, researchers can lay the groundwork for impactful and valuable contributions to the scientific community.

• Charlesworth Author Services
• 19 November, 2021

The rationale for one’s research is the justification for undertaking a given study. It states the reason(s) why a researcher chooses to focus on the topic in question, including what the significance is and what gaps the research intends to fill. In short, it is an explanation that rationalises the need for the study. The rationale is typically followed by a hypothesis/ research question (s) and the study objectives.

When is the rationale for research written?

The rationale of a study can be presented both before and after the research is conducted. 

• Before : The rationale is a crucial part of your research proposal , representing the plan of your work as formulated before you execute your study.
• After : Once the study is completed, the rationale is presented in a research paper or dissertation to explain why you focused on the particular question. In this instance, you would link the rationale of your research project to the study aims and outcomes.

The study rationale is predominantly based on preliminary data . A literature review will help you identify gaps in the current knowledge base and also ensure that you avoid duplicating what has already been done. You can then formulate the justification for your study from the existing literature on the subject and the perceived outcomes of the proposed study.

Length of the research rationale

In a research proposal or research article, the rationale would not take up more than a few sentences . A thesis or dissertation would allow for a longer description, which could even run into a couple of paragraphs . The length might even depend on the field of study or nature of the experiment. For instance, a completely novel or unconventional approach might warrant a longer and more detailed justification.

Basic elements of the research rationale

Every research rationale should include some mention or discussion of the following: 

• An overview of your conclusions from your literature review
• Gaps in current knowledge
• Inconclusive or controversial findings from previous studies
• The need to build on previous research (e.g. unanswered questions, the need to update concepts in light of new findings and/or new technical advancements). 

Example of a research rationale

Note: This uses a fictional study.

Abc xyz is a newly identified microalgal species isolated from fish tanks. While Abc xyz algal blooms have been seen as a threat to pisciculture, some studies have hinted at their unusually high carotenoid content and unique carotenoid profile. Carotenoid profiling has been carried out only in a handful of microalgal species from this genus, and the search for microalgae rich in bioactive carotenoids has not yielded promising candidates so far. This in-depth examination of the carotenoid profile of Abc xyz will help identify and quantify novel and potentially useful carotenoids from an untapped aquaculture resource .

In conclusion

It is important to describe the rationale of your research in order to put the significance and novelty of your specific research project into perspective. Once you have successfully articulated the reason(s) for your research, you will have convinced readers of the importance of your work!

A study rationale explains the reason for a study and the importance of its findings for a particular field. Commonly, you'll need to write a study rationale as part of a university course of study, although you may also need to write one as a professional researcher to apply for funding or other support. As a student, your study rationale also justifies how it fulfills the requirements for your degree program or course of study. Do research before you write your study rationale so that you can discuss the previous work your study builds on and explain its significance to your field. Thorough research is also important in the professional context because your rationale will likely become part of the contract if funding or support is approved. [1] X Research source

Describing What You Hope to Accomplish

• For example, suppose you want to study how working the night shift affects the academic performance of college students who are taking classes during the day. A narrow question would measure a specific impact based on a specific amount of hours worked.

• Justify the methodology you're using. If there's another methodology that might accomplish the same result, describe it and explain why your methodology is superior — perhaps because it's more efficient, takes less time, or uses fewer resources. For example, you might get more information out of personal interviews, but creating an online questionnaire is more cost-effective.
• Particularly if you're seeking funding or support, this section of your rationale will also include details about the cost of your study and the facilities or resources you'll need. [3] X Research source

Tip: A methodology that is more complex, difficult, or expensive requires more justification than one that is straightforward and simple.

• For example, if you're studying the effect of working the night shift on academic performance, you might hypothesize that working 4 or more nights a week lowers students' grade point averages by more than 1 point.

• Use action words, such as "quantify" or "establish," when writing your goals. For example, you might write that one goal of your study is to "quantify the degree to which working at night inhibits the academic performance of college students."
• If you are a professional researcher, your objectives may need to be more specific and concrete. The organization you submit your rationale to will have details about the requirements to apply for funding and other support. [5] X Research source

Explaining Your Study's Significance

• Going into extensive detail usually isn't necessary. Instead, highlight the findings of the most significant work in the field that addressed a similar question.
• Provide references so that your readers can examine the previous studies for themselves and compare them to your proposed study.

• Methodological limitations: Previous studies failed to measure the variables appropriately or used a research design that had problems or biases
• Contextual limitations: Previous studies aren't relevant because circumstances have changed regarding the variables measured
• Conceptual limitations: Previous studies are too tied up in a specific ideology or framework

• For example, if a previous study had been conducted to support a university's policy that full-time students were not permitted to work, you might argue that it was too tied up in that specific ideology and that this biased the results. You could then point out that your study is not intended to advance any particular policy.

Tip: If you have to defend or present your rationale to an advisor or team, try to anticipate the questions they might ask you and include the answers to as many of those questions as possible.

Including Academic Proposal Information

• As a student, you might emphasize your major and specific classes you've taken that give you particular knowledge about the subject of your study. If you've served as a research assistant on a study with a similar methodology or covering a similar research question, you might mention that as well.
• If you're a professional researcher, focus on the experience you have in a particular field as well as the studies you've done in the past. If you have done studies with a similar methodology that were important in your field, you might mention those as well.

Tip: If you don't have any particular credentials or experience that are relevant to your study, tell the readers of your rationale what drew you to this particular topic and how you became interested in it.

• For example, if you are planning to conduct the study as fulfillment of the research requirement for your degree program, you might discuss any specific guidelines for that research requirement and list how your study meets those criteria.

• In most programs, there will be specific wording for you to include in your rationale if you're submitting it for a certain number of credits. Your instructor or advisor can help make sure you've worded this appropriately.

Understanding Others, Educating Ourselves: Getting More from International Comparative Studies in Education (2003)

Chapter: 1 introduction and rationale, 1 introduction and rationale, introduction.

The increasing scrutiny of earlier studies has revealed their limitations and the consequent need for improvement in the planning, execution, and dissemination of international comparative research…. The lack of an adequate system of education indicators to inform education policy making has become increasingly apparent. Data are not collected regularly, systematically, or with enough coordination either to satisfy natural curiosity about education systems around the world or to answer the questions of researchers and policy makers about changes over time in education in a variety of countries. Trend data are needed on many aspects of education.

A Collaborative Agenda for Improving International Comparative Studies in Education (National Research Council, 1993, hereafter the 1993 Agenda)

By the last half of the 1990s, many concerns described in this excerpt from the 1993 Agenda of the Board on International Comparative Studies in Education had been or were well on the way to being resolved. The proposed solutions, however, produced several new, somewhat overlapping problems. Previously, there was a scarcity of data sufficiently robust to support valid cross-national comparisons; today, a glut of good-quality data overwhelms the field and remains largely unanalyzed, even as new follow-on surveys are launched. Previously, large-scale cross-national education surveys were initiated sporadically, every few years; however, between 1999 and 2003, data collection for at least one and as many as three surveys was scheduled annually.

Previously, U.S. schools faced few mandated tests, and most were willing to participate in the occasional voluntary, internationally oriented tests; today, with increased requirements for mandatory testing, increasing numbers of schools are unwilling to add to their testing burden by participating in voluntary assessments. The infrastructure for conducting large-scale international studies that has developed over the past decade, which plays an important role in ensuring the quality of large-scale international education surveys, has become institutionalized, and the desire to keep this infrastructure engaged has played a role in decisions to support new and more frequent studies. Indeed, there is an increasing concern that international assessments are now conducted more frequently than reforms can produce change in the U.S. education system, which may discourage ongoing, longer term reform efforts.

In addition, the results of large-scale domestic and international surveys are raising a host of questions that often are addressed best by smaller scale studies requiring a wide range of research methods, both qualitative and quantitative. For example, although a full series of more detailed thematic analysis of the data was commissioned before the completion of the first Programme for International Assessment of Student Achievement (PISA) 1 international report, it was of necessity carried out by researchers closely aligned with the study. Few new initiatives have been launched either to cull insight from ongoing nonsurvey-based international studies or to support systematic new ones attuned to independent research agenda.

Despite major investments in a half-dozen large-scale international surveys over the past decade, U.S. public discourse about education remains curiously untouched by international comparisons. Beyond the common knowledge that U.S. students are not first in the world in mathematics and science, educational rhetoric in the United States remains essentially one-dimensional, lacking the sense of rich possibilities that international perspectives can provide. Possible reasons for this deficiency include the general imperviousness of U.S. education policy to domestic or international education research (Lagemann, 2000), and widely shared assumptions that other areas of the world are simply not relevant to the United States. The lack both of interpretive international comparative education studies and of secondary analysis focused on issues of primary concern to the public and policy makers, however, certainly contributes

to the persistence of an inwardly focused approach to education studies in the United States.

The Education Sciences Reform Act of 2002 places strong emphasis on using rigorous scientific methods to study education (U.S. Congress, 2002). This act has reorganized the U.S. Department of Education’s Office of Educational Research and Improvement by creating the Institute of Education Sciences, which includes three centers: the National Center for Education Research, the National Center for Education Evaluation and Regional Assistance, and the National Center for Education Statistics (NCES), one of the main U.S. funders of international comparative education research. This is an important moment to examine the nature of international comparative education research and to reaffirm its critical contribution to a well-rounded program of domestic education research in the United States.

The purpose of this report—which is directed to federal sponsors of international comparative education research, domestic and international researchers, private foundations, and state and district officials who are eager to improve their part of the U.S. education system—is to lay out the rationale for such research; describe its scope, purpose, and potential impact; and make recommendations regarding future directions. Fundamentally, international comparative studies contribute to basic education research by documenting the existence of a much broader array of educational practices and outcomes than is available in the United States alone. International studies, however, can do much more than this. The rest of this chapter explores the current rationale for U.S. participation in international comparative studies and discusses the scope of such studies. Chapter 2 outlines the range of international comparative studies and their relative costs and presents recommendations for moving toward a more balanced research agenda for these studies. Chapter 3 draws on some recent studies to illustrate different ways that international comparative studies have—or, in some cases, have not—made an impact on the U.S. education system. Chapter 4 begins by offering suggestions for continuing to improve one type of study—large-scale, cross-national surveys— with which the board has been mainly involved since its inception, and to address key issues that persist or have emerged with those types of studies since the board’s 1990 report, A Framework and Principles for International Comparative Studies in Education (National Research Council, 1990, hereafter referred to as the 1990 Framework ). It continues by addressing the pressing need for more public access to the findings of all types of international comparative studies and the consequent need for an array of studies addressing a wide range of questions that call for many different research methodologies. Chapter 5 examines the implications of recommendations from earlier chapters for supporting infrastructure, both fi-

nancial and organizational, for future international comparative studies of education. The final chapter provides a summary of the board’s recommendations.

Although many features of international data collection in educational research have changed over the past decade, at least one has not: research that provides comparative information across nations continues to expand understanding of education as a social and economic institution and provide rich sources of ideas about how nations can strengthen teaching and student achievement. Throughout its history, the U.S. education system has benefited immensely from ideas borrowed and adapted from education systems in other countries. These ideas range from methods for early childhood education (France, Germany, and Italy), a model for the structure of higher education (Germany), and goals for mass urban education (England), to the Suzuki method of teaching music (Japan).

Holmes (1985) traces the earliest efforts to observe and learn from foreign education systems to Plato’s reference to Sparta in The Republic . He dates the beginning of comparative education as a systematic study to the early 19th century. He mentions early reservations about the limitations of what is likely to be learned from such study. He cited one educator who claimed that “the practical value of studying other systems of education is that much can be learned about one’s own system of education.” His second claim was that “what goes on outside the schools matters even more than the things inside schools to an understanding of any system of education” (p. 866).

U.S. interest in international education studies has waxed and waned over the decades, but it grew particularly keen after the National Commission on Excellence in Education issued its report, A Nation at Risk (National Commission on Excellence in Education, 1983) . That report made extensive use of findings from then-current national and international comparative studies of student achievement, portraying them in provocative terms. 2 The data cited in that report seized the interest of policy makers, who had little previous knowledge of or interest in comparative international education statistics but who subsequently evolved into strong proponents of comparative research at both state and cross-national lev-

els. 3 Some scholars, however, questioned the use of these particular international studies to judge the U.S. education system, given their imperfect sampling and other technical problems at that time. 4 Nonetheless, by 1990, the president and the governors acknowledged the importance of international perspectives in formulating domestic education policy when they defined national education goals for the nation. The United States was challenged to be first in the world in mathematics and science achievement by the turn of the century, and to ensure that every adult “will be literate and will possess the knowledge and skills necessary to compete in a global economy” (Rothman, 2002).

This focus on comparisons of achievement brought valuable attention to the potential benefits of learning about education in other countries. However, the country rankings that were so widely publicized did little to suggest the breadth of international research.

Cuban (1988) has argued that one remarkable feature of U.S. schools is how alike they are. In contrast, education systems in many other countries encompass a far greater degree of diversity. For example, there tends to be great diversity across nations regarding what citizens expect of their schools, what roles teachers play in society, and what education services governments and private organizations provide. International comparative research in education can help to expand the repertoire of possible practices and policies in several ways.

International education studies help to define what is achievable. How much can students learn and at what age can they learn it? How do different countries mix different amounts of pre-service and in-service professional development for beginning teachers at the early childhood, primary, secondary, and tertiary levels? How do different countries determine the optimal number of hours of schooling at each of these levels? What roles do parents with different levels of education play in governing and supporting schools? Most people would be reluctant to conduct controlled experiments with their children’s educations, but naturally oc-

curring variation in other countries can help develop more confidence in—or courage to consider changing—U.S. policies and practices. Studies such as PISA, for example, demonstrate that high average performance does not have to be associated with the wide disparities in performance found in the United States.

International comparative research can help researchers and policy makers to observe and characterize consequences of different practices and policies for different groups, under different circumstances . Research can examine correlates of various approaches (Holmes, 1985; Postlethwaite, 1999) and explore the reasons for observed differences in student performance, thus enhancing confidence in the generalizability of studies ( 1990 Framework ). It can also contribute to and possibly influence the content and direction of useful debate concerning public issues, such as teenage employment, and the terms of service of teaching, by enhancing the discourse through increasing knowledge about a wider range of alternatives and possible consequences.

International comparative studies often bring to light concepts for understanding education that have been overlooked in the United States, helping U.S. educators to think in terms of new principles and categories. The Second International Mathematics Study helped to popularize the concept of the intended, implemented, and achieved curriculum and facilitated more nuanced discussions and studies about relationships between curriculum and student achievement. A recent book highlighting the expert, “profound” understanding characteristic of Chinese elementary mathematics teachers (Ma, 1999) casts new light on layers of understanding within subject matter knowledge. PISA’s efforts to measure “preparedness for life” have led to new ways to operationalize different types of literacy.

International comparisons of education often lead us to identify and question beliefs and assumptions that are taken for granted . This contribution is sometimes characterized as making the familiar strange and the strange familiar (Kluckhohn, 1944). International comparisons help to raise questions about the universality of particular features of the U.S. education system and offer new insight into current disputes. For example, Japanese teachers can offer cogent reasons why classes of fewer than 20 students are more difficult to teach than larger classes, and why, at the preschool level, teachers often should not discipline a misbehaving student.

Large-scale cross-national surveys have received much attention in the United States in the two decades since the release of A Nation at Risk. Many of the benefits of international comparative education studies, however, are achieved by relatively small-scale, low-cost, more open-ended studies. Such studies, in addition to contributing to our understanding of

the broader range of possibilities in education, are essential precursors to large-scale studies because they help to identify contextual features of school systems that are common to many countries and can be quantitatively measured. Similarly, questions raised by counterintuitive findings of large-scale studies are often best explored by smaller scale, targeted studies.

International comparisons of education systems often produce outcomes that are not part of their original rationale but that nonetheless make valuable contributions to the improvement of U.S. education and international relations.

In an increasingly interdependent world, they provide useful insights into the socioeconomic structure of other countries and cultures. For example, the insights of comparative education scholars who, in relative obscurity, had studied religious schools in Central and South Asia became more valued at the end of 2001, when graduates of those schools attacked the United States.

The challenges posed by international studies can increase the educational research capacity of the United States as well as that of other countries ( 1990 Framework ). For example, the Trends in International Mathematics and Science Study (TIMSS) 5 Videotape Classroom Study helped to raise the technical sophistication of video research methods in the United States and elsewhere. Furthermore, questions of sampling, instrument design, data gathering, and data analysis that had to be addressed in the second and third international mathematics studies yielded results and experience that have been useful in national surveys of achievement.

All these benefits do not flow automatically from every study. Rather, they are more likely to result from systematic investments in a variety of studies, differing in methodology, scope, and purpose, at least some of which try to test and build on earlier findings. Simply observing and measuring apparently effective practices in other countries is not sufficient to bring about desired improvement in U.S. schools. Ideally, promising practices would undergo several rounds of study in the context of their country of origin, and in the United States, in which practitioners and researchers attempt to construct and test hypotheses about the rela-

tionship between the practice and desired outcomes in different settings. More often, informal experiments initiated by practitioners using innovations from other countries attract the attention of researchers post hoc; policy makers call on researchers to investigate promising practices; and, of course, researchers themselves may initiate exploratory studies. Instances of each of these cases are highlighted in boxes throughout the next chapter.

Since 1988, the Board on International Comparative Studies in Education (BICSE) at the (U.S.) National Research Council of the National Academies has engaged in activities designed to increase the rigor and sophistication of international comparative studies in education by encouraging synergies between large and smaller scale international comparative education research, to identify gaps in the existing research base, and to assist in communicating results to policy makers and the public. Under the current grant (1998-2002), funded by the National Science Foundation and the U.S. Department of Education's National Center for Education Statistics, BICSE has sponsored public events and commissioned papers on the effects of the Trends in International Mathematics and Science Study (TIMSS), the power of video technology in international education research, international perspectives on teacher quality, and advances in the methodology of cross-national surveys of education achievement. This report responds to a request from the board's sponsors under the current grant to produce a report that builds on its previous work.
