Clear guide to research design and research tools

We have recently introduced the book in one of our international courses in education: Research Design and Methodology in Educational Sciences. Our staff and students like the book and think it is excellent as an introduction to the field of methodology. It is pleasant to read and covers quantitative-, qualitative- and mixed-methods. I can recommend it to colleagues at other colleges or universities.

A lively, readable and above all indubitably well informed account of the knowledge and skills required to develop a logical research design in activation of an achievable and worthwhile piece of empirical research. If research design didn't exist, I would trust John and David Creswell to invent it!

Very good well designed and relevant contents.

Research Design: Qualitative, Quantitative, and Mixed Methods Approaches

Student resources, welcome to the sage companion site for  research design ,  sixth edition.

The sixth edition of the best-selling text,  Research Design: Qualitative, Quantitative, and Mixed Methods Approaches  by  John W. Creswell  and  J. David Creswell , continues to provide clear and concise instruction for designing research projects or developing research proposals. This user-friendly text walks readers through research methods, from reviewing the literature to writing a research question and starting a hypothesis to designing the study. At each step in the process, the text addresses qualitative, quantitative, and mixed methods approaches to encourage readers to choose the approach that best fits the research question. Numerous examples draw from a wide variety of disciplines, featuring diverse philosophical ideas and modes of inquiry. Features like bullet points, numbered steps, and annotated research examples help students focus on the most important information in research design.

The  Sixth Edition  has been fully revised to reflect the 7th edition of the P ublication Manual of the American Psychological Association  with more inclusive language, updated citation styles, and updated writing suggestions. Learning objectives are now included at the start of each chapter. To help readers better achieve these learning objectives, the authors have clarified and improved the writing exercises to help readers better achieve these learning objectives. The final three chapters detailing qualitative, quantitative, and mixed methods now have a parallel structure so readers can better compare and contrast these approaches. Chapter 10 on mixed methods in particular has been restructured to reflect the latest developments in mixed methods and best practices. New research examples throughout help capture and demonstrate new trends in research.

Creswell, J. W. (2014). Research Design: Qualitative, Quantitative and Mixed Methods Approaches (4th ed.). Thousand Oaks, CA: Sage

The book Research Design: Qualitative, Quantitative and Mixed Methods Approaches by Creswell (2014) covers three approaches-qualitative, quantitative and mixed methods. This educational book is informative and illustrative and is equally beneficial for students, teachers and researchers. Readers should have basic knowledge of research for better understanding of this book. There are two parts of the book. Part 1 (chapter 1-4) consists of steps for developing research proposal and part II (chapter 5-10) explains how to develop a research proposal or write a research report. A summary is given at the end of every chapter that helps the reader to recapitulate the ideas. Moreover, writing exercises and suggested readings at the end of every chapter are useful for the readers. Chapter 1 opens with-definition of research approaches and the author gives his opinion that selection of a research approach is based on the nature of the research problem, researchers' experience and the audience of the study. The author defines qualitative, quantitative and mixed methods research. A distinction is made between quantitative and qualitative research approaches. The author believes that interest in qualitative research increased in the latter half of the 20th century. The worldviews, Fraenkel, Wallen and Hyun (2012) and Onwuegbuzie and Leech (2005) call them paradigms, have been explained. Sometimes, the use of language becomes too philosophical and technical. This is probably because the author had to explain some technical terms.

Conducting a well-established research requires deep knowledge about the research designs. Doing research can be likened to jumping into the sea which may transform into a huge ocean if the researcher is not experienced. As a PhD candidate and a novice researcher, I believe that the book "Research Design: Qualitative, Quantitative and Mixed Methods Approaches" by J.W. Creswell is a true reference guide for novice researchers since it is the most comprehensive and informative source with its reader-friendly structure.

There are a number of approaches used in this research method design. The purpose of this chapter is to design the methodology of the research approach through mixed types of research techniques. The research approach also supports the researcher on how to come across the research result findings. In this chapter, the general design of the research and the methods used for data collection are explained in detail. It includes three main parts. The first part gives a highlight about the dissertation design. The second part discusses about qualitative and quantitative data collection methods. The last part illustrates the general research framework. The purpose of this section is to indicate how the research was conducted throughout the study periods.

Chapter Seven:Research Questions and Hypotheses RESEARCH DESIGN Qualitative, Quantitative, and Mixed Methods Approaches Third Edition John W. Creswell

Chapter Outline • Qualitative Research Questions • Quantitative Research Questions and Hypotheses • A Model for Descriptive and Inferential Questions and Hypotheses • Mixed Methods Research Questions and Hypotheses

Qualitative Research Questions • Qualitative researchers pose research questions • Not objectives • Not hypotheses • Two types of qualitative research questions to focus a study's purpose: • Central question • broad question that asks for exploration of the central phenomenon • Subquestions • Questions that narrow the focus of the study

Writing Qualitative Research Questions • Ask 1-2 central questions and no more than 5-7 subquestions • These questions should: • Relate the central question to the strategy of inquiry • Begin with "what" or "how" • Focus on a single phenomenon or concept • Use exploratory verbs like discover or describe • Avoid directional words such as "affect" or "impact" • Evolve during the study • Be open-ended without reference to the literature • Specify the participants and research site (unless stated previously)

A Script for Writing a Qualitative Central Question • (How or What)is the(“story for” for narrative research; “meaning of” the phenomenon for phenomenology; “theory that explains the process of ” for grounded theory; “culture-sharing pattern” for ethnography; “issue” in the “case” for case study)of (central phenomenon)for(participants)at(research site).

Quantitative Research Questions and Hypotheses • Quantitative researchers pose research questions or hypotheses to focus the study's purpose • Quantitative research questions: • Questions about the relationships among variables that the investigator seeks to know • Quantitative hypotheses: • Predictions that the researcher makes about the expected relationships among variables • Predictions about the population values that the researcher will estimate based on data from a sample • Quantitative objectives: • Indicate a study's goals • Used frequently in proposals for funding

Writing Quantitative Research Questions and Hypotheses • Write questions or hypotheses, not both • Consider 3 approaches to the variables for a question or hypothesis: • Compare groups • Relate variables • Describe responses • Specify questions and hypotheses based on theory if possible • Measure the independent and dependent variables separately • Generally use demographic information as intervening variables • Use consistent words and ordering for independent and dependent variables

Scripts for Writing Quantitative Research Questions and Hypotheses • Does (name the theory) explain the relationship between (independent variable) and (dependent variable), controlling for the effects of (control variable)? • There is no significant difference between (the control and experimental groups on the independent variable) on (dependent variable).

Forms for Writing Quantitative Research Questions and Hypotheses • If writing hypotheses, use a consistent form: • Null hypotheses (predict no difference or no relationship) • Directional hypotheses (predict direction of difference or relationship) • Nondirectional hypotheses (predict a difference or relationship, but not its direction) • If writing research questions: • First, specify descriptive questions for each important variable • Next, state inferential questions that relate variables or compare groups • Finally, add questions in which variables are controlled

Mixed Methods Research Questions and Hypotheses • Advance both qualitative and quantitative research questions (or hypotheses) • Use guidelines for writing good qualitative and quantitative questions and hypotheses • Order questions to match the mixed methods design • In a two-phase design, order to match the phases • In a one-phase design, order according to the method given the most weight • Include a mixed methods research question that • Directly addresses the mixing of the two strands • Is written to convey the procedures or the content of the study

Different Ways to Write Questions and Hypotheses into a Mixed Methods Study • Write separate qualitative questions and quantitative questions or hypotheses: • At the beginning or as they emerge in phases • This places emphasis on the two approaches • Write separate questions or hypotheses followed by a mixed methods question: • This highlights the two approaches as well as their combined strength • Write only a mixed methods question: • This emphasizes the integration and not the individual parts

Chapter Questions

For a qualitative study, write one or two central questions followed by five to seven subquestions.

For a quantitative study, write two sets of questions. The first set should be descriptive questions about the independent and dependent variables in the study. The second set should pose questions that relate (or compare) the independent variable(s) with the dependent variable(s). This follows the model presented in this chapter for combining descriptive and inferential questions.

Write a mixed methods research question. Write it first as a question incorporating the procedures of your mixed methods study and then rewrite it to incorporate the content. Comment on which approach works best for you.
