Chapter 7Introduction to Qualitative Research 120
Characteristics of Qualitative Research 121Qualitative research uses the natural setting as the direct source of data and the researcher as the key instrument 122
Qualitative research is descriptive 123
Qualitative research is concerned with process, rather than simply with outcomes or products 124
Qualitative research includes an inductive analysis of data 124
Meaning is subjective and of essential concern to the qualitative approach 124

Preface
A fearsome creature stalks the pages of this book. His name is the Gremlin. The Gremlin represents the critic who punches holes in any research design and who finds something wrong in nearly every study. Every student of research in educa-tion fears the Gremlin, whether the Gremlin is a real person or merely a figment of the imagination.
The Gremlin can be tough, but also fair, and it’s possible to meet the Gremlin’s requirements. That’s what this book is about. Educational Research in an Age of Accountability is written to give students of research in education a clear explanation of the logic behind design, analysis, and writing of research, so you can both understand and critically evaluate research done by others and do research yourself that is meaningful to you, valuable to the field, and satisfying to the Gremlin. In this era of standards-based edu-cation and evidence-based practices, teachers are often asked to offer proof of effectiveness for the strategies used in the classroom. Possessing the basic knowledge and skills in educational research is a valuable tool in today’s education climate.
I have a few admissions to make. First, I love this stuff. I hope in writing this book I’ve communicated my enthusiasm for the subject, and I hope you’ll come to share my enthusiasm. To me, research in education is not merely an academic exercise, it’s a
way to improve the practice of education for children. Every educator knows the potential children possess and wants to maximize that potential. A researcher has the opportunity to make a lasting impact by bringing new knowledge to bear on issues that are important to children everywhere. It is endlessly exciting if you do it right. Savvy readers of research can enrich their understanding of effective educa-tion, and protect themselves from misleading claims.
I’ve done a lot of research, using a wide variety of research designs in a wide variety of settings involving children from pre-K to high school. For this reason, I’m going to tell you how research is really done, not how it should be done theoreti-cally. Not everyone who reads this book will become a researcher, but everyone will need to understand research and be able to read it critically. I hope you will learn not only how to satisfy the Gremlin but also how to be the Gremlin, to become a sharp-eyed critic of research able to recognize research that is valid and meaningful from research that is not.

How This Book Is OrganizedThis book is organized somewhat differently from other books on research methods. After an introduction (Part I) follow eight chapters on various research designs: five quantitative (Part II: Quantitative Research Designs), and three qualitative (Part III: Qualitative and Action Research Designs). These designs serve as the core of the book as they present the logic of experimental design, the strengths and limitations of each approach, and the kinds of research problems each is intended to address.
Part IV, Planning and Implementing Research, discusses the practicalities of research: evaluating internal and external validity, measurement, and then setting up a study of your own, which involves choosing a topic, doing literature reviews, and writing research proposals. This is the point at which you may likely be plan-ning your own research, either as an exercise or in preparation for the real thing.
Part V, Data Analysis, is a practical, easy-to-follow guide to basic and interme-diate statistics that focuses on the ideas behind the numbers, not only on compu-tational procedures. Finally, Part VI, Reading and Reporting Research, discusses reading research and writing research reports.
Features in This TextThroughout Educational Research in an Age of Accountability, special features draw the reader’s focus to issues of recurring importance in the field of educational research as well as to aid with review and understanding of key concepts in educa-tional research.
In a time when educators are held accountable for learning outcomes, the in-formal, nontechnical style of the book offers pre- and in-service educators the basic understanding of research needed to understand research findings and conduct studies of their own.
The Gremlin, representing a re-search critic, shows up throughout the book as a personification of the world of critical readers of research, including professors and editors. By learning how to satisfy the Gremlin, stu-dents also learn to ask themselves critical ques-tions as they design their own research and to intelligently respond to others’ research, while learning to become critical readers.
The Savvy Researcher features alert the reader to common errors and misleading uses of research in education, so that students will become critical consumers of research.

The Savvy Researcher
Watch for Disadvantages in Measurement
W hen reading experimental research, the Gremlin is always on the lookout for measures that may give an advantage to the experimental group. For example, imagine a month-long study in which the ex-
perimental group completed elaborate projects relating to the cultures of South America, while the control group experienced a traditional survey course on world cultures. The posttest focused entirely on South America.
“Preposterous!” fumes the Gremlin. “Such a study will be seriously biased to-ward the experimental group, which presumably spent much more time on South America during the study month!”
Studies often report results of assessments used just to check to see that the treatments were implemented. For example, a reading comprehension program emphasizing teaching students to summarize might use a measure of summariza-tion skill (when the control group did not learn to summarize). There is nothing wrong with this if the implementation measure (summarization, in this case) is clearly labeled as such and a measure that is fair to both groups (e.g., a compre-hension measure) is the only outcome that matters. Yet all too often, researchers report so-called positive effects of treatments on outcomes that only assess expo-sure to particular content, not better teaching strategies.

Research with Class features contain appli-cations of the principles of research in each chapter to studies that could be done in a single class or school, answering questions practicing educators might ask. Each feature demon-strates how educators with limited resources can do research in their own settings. They also bring the principles of research down to earth by showing how they can be used to shed light on realistic questions that educators face.

Research with Class
Using Case Study to Inform
Joan Bukowski, a kindergarten teacher, read several articles indicating that sociodramatic play serves an important role in young children’s language de-
velopment (e.g., Cooper & Dever, 2001; Mellou, 1994). Although she had always had a dramatic play center in her classroom, she had not given much thought to how children really benefited from it.
Joan decided to conduct a case study of the dramatic play center in her class. She filled out a checklist of which children played in the dramatic play center. She conducted running-record observations of the children’s behavior in the dramatic play center, recording the different kinds of behaviors they engaged in while in the center. She interviewed the children about what they liked to do in the dramatic play center, what materials they used the most, and what additional materials they would like in the center.
Joan’s observations and interviews indicated that it was mostly the girls in her class who played in the dramatic play center. Based on these data, Joan added materials that she thought would attract the boys to the center, including Hoover, the class hamster, a big favorite with the boys. She continued her obser-

................................................................
The final chapter, Writing Up the Study, focuses on writing master’s theses and other research reports.
Actual research articles, annotated with notes that highlight critical issues, are included in the book appendixes to assist readers’ understanding and critical thinking skills.
Strong pedagogical aids help students retain and test their understanding of key concepts. The text is filled with both real examples and “thought experi-ments” intended to link key concepts of research to students’ own experiences. In addition, aids include margin glossary definitions and review exercises at the end of each chapter intended to help students think about and apply what they have learned in simulated research contexts. The statistics chapters (13 and 14) have specific answers, which are provided in the appendices section at the back of the book.
Throughout the text, cartoons drawn by my colleague James Bravo take the technical subject of research and shine a humorous light on it, while encouraging the reader to think about some key concepts of research methods and to serve as mnemonics for some of the vocabulary of research.
Special activities using Research Navigator are also included at the end of every chapter. This powerful research tool allows readers to in vestigate key con-cepts from the book using a collection of resources available online at www.researchnavigator.com, in-cluding EBSCO’s ContentSelect Academic Journal Database and the New York Times. Purchase of this book allows you free access to this exclusive pool of information and data. A personal code and access in-structions are included on the inside cover of this book.

USING RESEARCH NAVIGATORTM This edition of Educational Research in an Age of Accountability is designed to integrate the content of the book with the valuable research tool, Research NavigatorTM, a collection of research databases, instruction, and contemporary publications available to you online at www.researchnavigator.com.
At the end of every chapter a Research NavigatorTM section prompts the reader to use key terms in each chapter to expand on the concepts of the text and further explore the work being done throughout the field of education. To gain access to Research NavigatorTM, go to www.researchnavigator.com and log in using the passcode you’ll find on the inside front cover of your text. Research NavigatorTM learning aids include the following components:
EBSCO’s ContentSelect Academic Journal Database EBSCO’s ContentSelect Academic Journal Database contains scholarly, peer-reviewed journals. These published articles provide you with specialized knowledge and informa-tion about your research topic. Academic journal articles adhere to strict scientific guidelines for methodology and theoretical grounding. The information obtained in these individual articles is more scientific than information you would find in a popular magazine, newspaper article, or on a web page.
The New York Times Search by Subject Archive Newspapers are consid-ered periodicals because they are issued in regular installments (e.g., daily, weekly, monthly), and provide contemporary information. Information in periodicals may be useful, or even critical, for finding up-to-date material or information to support specific aspects of your topic. Research NavigatorTM gives you access to a one-year, “search by subject” archive of articles from one of the world’s leading newspapers—The New York Times.
“Best of the Web” Link Library Link Library, the third database included with Research NavigatorTM, is a collection of web links, organized by academic subject and key terms. Searching on your key terms will provide you a list of five to seven editorially reviewed websites that offer educationally relevant and reliable content. The web links in Link Library are monitored and updated each week, reducing your incidence of finding “dead” links.
In addition, Research NavigatorTM includes the following extensive online con-tent detailing the steps in the research process:
