Writing the Introduction

Writing the introduction

The introduction chapter of your dissertation sets the stage for your study and typically consists of the following sections: the research problem, the theoretical or conceptual framework, purpose statement, research questions/hypotheses, significance of the study, delimitations, assumptions, definition of terms, organization of the remaining chapters, and a summary that states the key points made in the chapter. Most introductions in the social sciences follow a similar pattern; however, they may vary according to the type of research methodology used.

Usually, the overall structure of Chapter 1 moves from the general to the specific, beginning with an overview of the general area under study and ending with specific research questions/hypotheses. Think of writing Chapter 1 in a V or funnel-shaped fashion, as shown in Figure 11.1.

Let me elaborate on this funnel notion by guiding you through a thinking process to focus your introduction. First, draw a large funnel and fill it in to help you visually focus your topic. The top of the funnel begins with a description of the general area to be studied. Next, identify a more specific problem within the general area. Say why this problem is important to study and specify what is already known about the problem. Then, specify what is not known about the problem that is important to study. Finally, state a specific purpose statement in one or two sentences followed by research questions that guide the study.

Problem Statement

A research problem can be defined as “the issue that exists in the literature, in theory, or in practice that leads

to a need for the study. The research problem in a study becomes clear when the researcher asks, ‘What is the need for this study?’ or ‘What problem influenced the need to undertake this study?’” (Creswell, 2002, p. 80). Basically, the problem statement provides an overview of the study. It states (1) what the study is about, (2) why it is important and timely, (3) what contributions are made to knowledge and practice, and (4) how the study fits into the existing state of the art. The problem statement tells the story behind the variables or concepts to be studied and provides background for the purpose statement and research questions.

Figure 11.2 Example of Using a Funnel to Develop and Narrow the Problem Statement

The problem statement should do the following:

• Have a line of logic that leads the reader to the purpose statement • Provide a background to the variables or concepts to be studied • Cite literature sources, but not extensively • Conclude with the “need to know”

Line of Logic

The problem statement begins with a general introduction to the study and, through a careful line of reasoning, focuses down to become more detailed and specific to your study. Your writing should be clear, precise, and directional. There should be a sequential line of logic. “The delineation of the problem leads directly to the statement of the purpose. The purpose of any study is to help solve the stated problem” (Martin, 1980, p. 40). An important point to remember is that the line of logic comes from you. It cannot be found directly in the literature.

Background to the Study

Providing background information to the study requires answering the following questions:

• 1. What do we already know about this topic?

• 2. What do we not know about this topic? What has not been answered adequately in previous research

and practice? • 3.

What do we want to know about this topic?

The problem statement is the discrepancy between what we already know and what we want to know. It is necessary to provide background information about both what is known and what is not known. The problem statement also tells the story about why we care—why we should conduct this study. It is important for the reader to know what is unique and different from previous research. Try to conceive of your study as a large jigsaw puzzle with a piece missing. Or you may conceive of your study as fulfilling an indicated need for further advancement of previous research. That missing piece is the gap you want to fill. To discover that missing piece, you must read widely in the literature base of your topic area.

When all of these studies are aggregated, you can then tell something about the problem's domain. (See Figure 11.3.)

Figure 11.3 Defining the Problem's Domain

Literature Sources

The variables or factors you selected for study must exist within some conceptual or theoretical framework that you develop from reading the literature. You cannot just pull your topic out of a hat. Appropriate citations from the literature help provide a justification for selecting these variables or concepts. Creating a conceptual framework is one of the few places where you have the opportunity to display original thought. If, however, you conduct an inductive qualitative study, your variables or concepts emerge from the data. Rather than starting with a conceptual framework, you investigate broad, general areas that become more focused through data gathering in the field.

Your problem statement must explain how your study fits into the existing state of the art. Martin (1980), in his book Writing and Defending a Thesis or Dissertation in Psychology and Education, delineated some of the circumstances into which your problem might fit:

• 1. There is little or no research on a particular topic.

SAGE © 2010 by Carol M

SAGE Books

Page 4 of 14 SAGE Books - Writing the Introduction

• 2. There is some research but it has not been applied to enough samples or in enough situations to be considered a reliable phenomenon.

• 3. There is a good deal of research, but the findings are contradictory. (pp. 39–40)

Citing the literature helps you build a case for why your research should be undertaken. The references and quotations support your arguments. However, keep in mind that in most cases, citations should be used sparingly in the problem statement. It is not a formal review of the literature.

For impact, keep your sentences short and write an opening sentence that stimulates interest. In short, your introductory chapter should convince your readers of the study's need and value.

Need to Know

What is the need for this particular study? Why does this specific study need to be conducted? So what? What will your study add to the knowledge base? “The need for the study is established by showing that there is a problem of some importance, establishing that there is a gap in the knowledge base, and by showing why filling that particular gap is important or at least relevant” (Ogden, 1993, p. 84). However, the major discussion of the study's importance may be found in the section “Significance of the Study.”

Common Errors in Writing the Problem Statement

Here are some common errors students make in submitting drafts of their problem statements.

• Failing to get to the point. Avoid tedious length in introducing the study. The reader wants to know what your study is about.

• Making the reader believe that we already know the answer. If we know it, then we don't need to study it.

• Covering extraneous issues, whether interesting or not. These are “rabbit runs”—interesting but irrelevant to the topic. Resist the temptation to share with the reader the volume of interesting but irrelevant information you accumulated.

• Being inconsistent. The problem should be clearly and logically related to the purpose statement and research questions.

• Stating what we should do rather than what we want to know. Such phrases as “we must …,” “we should …,” and “it is imperative that …” belong in a position paper. In short, stay off a soapbox.

• Writing in “dissertationese” rather than in English. This causes your writing to be stilted, awkward, and artificial. Just say what you mean in natural phrases.

• Using unnecessary technical language and jargon. This keeps the reader from understanding the main idea of what you're trying to say.

• Using extensive quotations and references. These get in the way of the logical flow of ideas. • Using abstruse arguments. Refrain from making points that are unclear or difficult to understand.

Write in a clear, simple, and straightforward manner. • Engaging in personal reflections or editorializing. Reserve this for Chapter 5. • Making unsupported claims or statements. The problem must be written in the context of theory and

relevant literature. • Using disjointed recitation of the studies cited. You create the line of logic and use literature citations

to substantiate your points.

The opening sentences of your dissertation should be approached thoughtfully and carefully, for this is the place to win or lose your audience. Therefore, introduce your topic in a way that engages readers—that captures their interest and makes them want to continue reading. Creswell (2008) called these opening lines the “narrative hook,” a term he claimed is “drawn from English composition, meaning words that serve to draw, engage, or hook the reader into the study” (p. 102). A convincing narrative hook, according to Creswell (2005), could include the following:

SAGE © 2010 by Carol M

SAGE Books

Page 5 of 14 SAGE Books - Writing the Introduction

• 1. Statistical data (e.g., “More than 50 percent of the adult population experiences depression today.”)

• 2. A provocative question (e.g., “Why are school policies that ban smoking in high schools not being enforced?”)

• 3. A clear need for research (e.g., “School suspension is drawing increased attention among scholars in teacher education.”) (p. 67)

There are a variety of other possibilities for introducing your study; the main thing to remember is to begin in an engaging manner that will interest your audience so they keep on reading.

Theoretical or Conceptual Framework

Doctoral students hate to hear these words from their dissertation advisor: “Your study sounds promising, but what is your theoretical framework?” This question is often met with silence, raised eyebrows, or shrugged shoulders indicating more information is needed about this term. In discussing the theoretical framework, Merriam (2001) stated, “A colleague of mine once commented that if she could have figured out what a theoretical framework was early on, she could have cut a year off of her graduate studies! Indeed, the theoretical or conceptual framework of a study and where theory fits into a research study continue to mystify and frustrate many a novice (and sometimes experienced) researcher” (pp. 44—45). Few texts or books about writing a dissertation or thesis discuss the process, importance, or purpose of developing a conceptual or theoretical framework and making it explicit. It is often the missing link in student scholarship. Hopefully, this section will ground your understanding in this important aspect of designing and clarifying your research.

What is a Conceptual or Theoretical Framework?

It is a lens through which your research problem is viewed. It can be a theory, a construct that conceptualizes your study's focus, or a research perspective. Miles and Huberman (1994) defined it this way: “A conceptual framework explains, either graphically or in narrative form, the main things to be studied—the key factors, constructs, or variables—and the presumed relationships among them. Frameworks can be rudimentary or elaborate, theory-driven or commonsensical, descriptive, or causal” (p. 18). Some of the visual forms a conceptual framework might take could be tree diagrams, mind maps, flow charts, concept maps, or diagrams such as triangles, circles, and so on. In their book, Qualitative Data Analysis, Miles and Huberman (1994) provided several graphic illustrations followed by descriptive narrative that served as examples of conceptual or theoretical frameworks.

The conceptual or theoretical framework provides the boundaries, or scaffolding, for your study. Like a microscope, it narrows your field of vision, thus helping you limit the scope of your study. After all, it is usually not possible to study everything about your research topic. A conceptual or theoretical framework identifies which of the “key factors, constructs, or variables” (Miles & Huberman, 1994, p. 18) are in and which are out. Making your conceptual or theoretical framework explicit provides clarity for the reader as to exactly what your study is about and provides the focus and content for making decisions about your study's design. By not grounding your study within an explicit conceptual or theoretical frame, your study takes on a “so what?” quality.

How does a Conceptual Framework Differ from a Theoretical Framework?

Often, the terms conceptual framework and theoretical framework are used interchangeably, and rarely is a differentiation made. A theory is a discussion about related concepts, assumptions, and generalizations, while concepts can be defined as words or phrases that represent several interrelated ideas. If your study is grounded in a particular theory or theories, then perhaps the better term would be theoretical framework, since theory would be used to explain the particular phenomenon under study. It implies a higher level of conceptual organization. If your study does not include a specific theory, it still contains concepts and

SAGE Books

Page 6 of 14 SAGE Books - Writing the Introduction

subconcepts that define the interrelationship of the ideas contained in your study. Some studies contain a review of theory as well as a conceptual framework. I recommend a conference with your dissertation advisor to determine the best approach for your particular study. Remember, no study is without some implicit framework. Your challenge is to discover it and make it explicit.

Why Do You Need a Conceptual or Theoretical Framework?

A well-defined conceptual or theoretical framework helps you to view your area of interest more acutely. Like a telescope or microscope, a conceptual or theoretical framework narrows and brings into focus your field of vision, which is necessary for limiting the scope of your study. It helps define the research problem and structures the writing of your literature review. In addition, it acts as a filtering tool to select appropriate research questions and to guide data collection, analysis, and interpretation of findings. According to Merriam (2001), “All aspects of the study are affected by its theoretical framework” (p. 47).

How Do You Find a Conceptual or Theoretical Framework?

The best way to select an appropriate conceptual or theoretical framework for your study is to immerse yourself in the research and theoretical literature related to your topic of interest. You may not find a specific theory to guide your study; however, you will discover a variety of interrelated core concepts and subconcepts from which to frame your study.

Example 1 of a Conceptual Framework

Following are sections from a quantitative dissertation about student persistence and academic success in an institution of higher education. The researcher prepared a separate section in Chapter One devoted to the study's underlying theories.

Conceptual Framework

To properly frame this study … it was appropriate to go to the recognized experts in college persistence. These theorists studied college persistence for over 35 years and developed models that have been tested and validated.

Student persistence is complex, made up of many variables (Lewallen, 1993). Studies since the 1970s attempted to isolate the most important and influential elements of student retention, attrition, and ultimately persistence to bachelor degree completion. Two theorists who heavily influenced the direction of this research were Vincent Tinto and Alexander Astin (Blecher, Michael, & Hagedon, 2002; Colbert, 1999; Hutto, 2002).

Vincent Tinto in 1975 developed his “Model of Student Departure,” which postulated that students come to a college with a particular background molded by their own unique genetics and environmental experiences and are guided by certain aspirations toward particular goal completions. This background and goal setting impacted the academic and social integration of the student at the university. Ultimately, Tinto theorized that the successful academic and social integration of a student led to successful persistence to degree completion (Blecher, Michael, & Hagedorn, 2002; Tinto, 1975). Tinto's theory has been widely quoted and reviewed over the last 30 years as evidenced by over 400 citations and at least 170 dissertations focusing on this theory (Braxton, Milem, & Sullivan, 2000). The basic precepts of the theory have been affirmed by many researchers (Aitken, 1982; Benjamin, 1993; Pascarella, 1983; Terenzini, 1980, 1977, 1985).

In 1970, Alexander Astin began with a general education model focusing on how students are impacted by their college experience. He then developed and expanded it over the next few years and referred to it as the “Input-Environment-Output” persistence model (Astin, 1970, 1975). Students enter higher education with unique “input” variables, again based on their own genetics and particular environmental experiences (Astin, 1970). Astin described these inputs as…Astin defined the “environment” variables as “those aspects of higher

Page 7 of 14 SAGE Books - Writing the Introduction

educational institutions that are capable of affecting the student” (Astin, 1970, p. 3). These environmental variables can be anything from institutional policies, associations with other students, support programs, facilities, to specific curriculum (Astin, 1970).

The final aspect of the model, the “output” variables, refers to …In conjunction with this structure, Astin designed a “Theory of Involvement” and theorized that the level of involvement of a student's interactions within the university environment was a major factor in the eventual persistence of the student (Astin, 1970, 1984).

… Hutto's literature review on student retention revealed that Astin is considered the foremost researcher on student involvement theory primarily because …Astin has led the nation's longest running study of college environments (Astin, 2003).

Both Tinto and Astin use an Input-Environment-Output approach to student persistence. Both acknowledge the role of student biological and environmental independent variables on the dependent outcome variables of persistence and ultimate academic success and the possible mediating role of university environmental variables on the input variables.

Note: The researcher then proceeded to describe the applicability of the Input-Environment-Output Model to his particular study.

Spindle, B. (2006). A study of Alaska native student persistence and academic success at the University of Alaska Anchorage. Doctoral Dissertation, University of La Verne.

Example 2 of a Conceptual Framework

This example is from a dissertation titled “An Exploratory Study of the Ways in Which Superintendents Use Their Emotional Intelligence to Address Conflict in Their Organizations” by Lori Geery (1997). Her purpose was the following:

The purpose of this study was to describe the knowledge, skills, behaviors, and strategies associated with emotional intelligence that superintendents perceived they use to address conflict in their organizations. This study also determined the impact use of emotional intelligence had on superintendents’ perceptions of their ability to lead and manage their organizations. (Geery, 1997)

The conceptual framework for this study was the five concept areas of emotional intelligence: understanding their own emotions, managing their own emotions, motivating themselves, recognizing emotions of others, and handling relationships with others. The matrix that outlines this conceptual framework follows. Notice how this framework mirrors the purpose of the study.

To see additional examples of describing a conceptual or theoretical framework, refer to John Creswell's book, Research Design: Qualitative, Quantitative, and Mixed Methods Approaches (2nd ed.). In this book, Creswell (2002) provided models for writing a quantitative theoretical perspective section (see pp. 127–130). He also provided a description and examples of qualitative theory use (see pp. 131–136).

Purpose Statement

By the time the reader gets to the purpose statement, there should be no doubt about what you will be doing in your study. The purpose statement, usually written in a single sentence or paragraph, clearly and succinctly states the intent of your study—what exactly you're going to find out. It represents the essence of your study and reflects its parameters. The purpose statement, according to Creswell (2009), “is the most important statement in the entire study, and it needs to be clearly and specifically presented” (p. 111). The purpose is clarified when you specify the variables or concepts under study and indicate whether your study is descriptive in nature or whether it is a relationship or differences study. In any one study, you may find one or more of these three types of measurements. Following are some examples to help you differentiate among them:

Example 1: A Purpose Statement in a Descriptive Study

The purpose of this study was to determine which strategies principals used to implement shared decision making in selected elementary schools and to determine how effective they were perceived to be by the principal, a teacher, and a parent at each site. (Walkington, 1991)

Example 2: A Purpose Statement in a Relationships Study

The purpose of this study was to identify the relationship between the perceived effectiveness of teacher work

SAGE Books

teams and teacher motivational needs.

Example 3: A Purpose Statement in a Differences Study

The purpose of this study was to determine whether there is a significant difference between the limited- English-speaking high school students attending year-round schools and limited-English-proficient students attending traditional high schools in the areas of (1) student attendance, (2) student grade point average, (3) student academic achievement as measured by units earned toward graduation, and (4) student oral English- language acquisition as measured by Language Assessment Survey (LAS). (Miranda, 1993)

Example 4: A Purpose Statement in a Differences and Relationships Study

The purpose of this study was to determine the differences between public and non-public school special education principals and teachers of students with severe emotional disturbances on their leadership orientations. It also determined whether a relationship existed between these leadership orientations and variables of school success as measured by student absenteeism, suspensions, expulsions, and teacher absenteeism. (Hernandez, 1996)

Example 5: A Purpose Statement in a Descriptive and Differences Study

The purpose of this study was to describe the collective bargaining procedures used by selected community college districts and the climates of the colleges. It was also the purpose of this study to describe the differences between a population with training in non-adversarial collective bargaining strategies and a population without training in collective bargaining strategies. (Garcia-Lipscomb, 1997)

Remember

Include in each chapter the purpose statement and research questions. Be sure they appear exactly the same throughout the dissertation. Don't get creative!

It is important to realize that purpose statements vary according to specialized research designs. A qualitative purpose statement uses words drawn from that specialized line of inquiry and often reflects the procedures of an emerging design format. Sometimes qualitative researchers use words such as intent, aim, or objective to draw attention to the study's intent. Examples that illustrate the difference between qualitative, quantitative, and mixed-methods purpose statements can be found in Research Design: Qualitative, Quantitative, and Mixed Methods Approaches by Creswell (2009).

Research Questions/Hypotheses

“A question well stated is a question half answered.”

Your topic was introduced, background information provided, and the purpose clearly stated. In this section of the dissertation, you state the research questions or hypotheses for the study. Your research questions/ hypotheses guide the study and usually provide the structure for presenting the results of the research. Generally, good research questions should have the following:

• Clear variables/concepts • Obvious measurement type (description, relationship, difference) • No how or why questions • “Thing words” clarified (success, processes, achievement, factors, etc.) • No questions that can be answered by counting or by answering “yes” or “no”

In quantitative studies, research hypotheses state the expectations of the researcher concerning the

SAGE Books

Page 10 of 14 SAGE Books - Writing the Introduction

relationship between variables. They indicate what the researcher thinks the outcome of the study will be. If your study is looking at differences, you may wish to state your hypotheses as null hypotheses that state there is no difference between variables. Following is an example of a descriptive purpose statement with research questions. Notice the alignment between them. The research questions operationally define the general terms used in the purpose statement (e.g., changes and factors).

Example

Purpose Statement

The purposes of this study were to describe the changes that occurred at three California middle schools where school-linked services were delivered and to identify the factors that facilitated and barriers that impeded the delivery of services.

Research Questions

• 1. What services were delivered at California middle schools, and how did students access these services?

• 2. What changes occurred in the resources of money, personnel, facilities, time, and energy?

• 3. What changes occurred in the roles and responsibilities of school personnel?

• 4. What changes in curricular or extracurricular areas occurred since the delivery of school-linked services?

• 5. What changes in student discipline or parent involvement occurred since the delivery of school-linked services?

• 6. What factors at the school sites facilitated the delivery of school-linked services?

• 7. What barriers impeded the delivery of school-linked services?

SOURCE: Kinley (1996).

Because the qualitative research paradigm is characterized by the emergence of questions during the course of data collection and analysis, the author may (a) present the original research questions in this chapter and then, in the methodology chapter, discuss how these changed during data collection and analysis; or (b) present the final questions that emerged during data collection and analysis.

Significance of the Study

This section is a more detailed explanation of the why of your study. Does it explore an important issue, meet a recognized need, or fill in a gap in the knowledge base? You must build an argument for the worth or significance of your research—how it should be useful to knowledge, practitioners, and policy makers.

You have to convince your reader, especially your advisor and committee, of the need for this particular study. To support your argument, you can summarize writings of experts who identified your problem as an important one and urged that research be conducted about it. Second, you can show specific data that indicate the severity of the problem and the need to resolve it.

Ogden (1993) provided some important points to remember about writing this section. First, she stated, “The rationale should be understandable to any reasonably educated individual, not just to people in your field.”

SAGE © 2010 by Carol M

SAGE Books

Page 11 of 14 SAGE Books - Writing the Introduction

Second, she cautioned you not to “oversell the contribution to the field.” It will not necessarily solve a national problem. Finally, she pointed out that “no matter which way the results come out, the value of this study could be defended” (Ogden, 1993, p. 86).

Creswell (2009) provided additional insight into writing the significance section of your dissertation. In designing this section, he advises including the following:

• Three or four reasons that the study adds to the scholarly research and literature in the field • Three or four reasons about how the study helps improve practice • Three or four reasons as to why the study will improve policy (p. 107)

Delimitations

This section clarifies the boundaries of your study. It is the way to indicate to the reader how you narrowed your study's scope. You control the delimitations—what will be included and what will be left out. Following are some typical delimitations:

• Time of the study: February 2008 through April 2009 • Location of the study: districts in southern California or urban areas only • Sample of the study: principals and superintendents • Selected aspects of the problem • Selected criteria of the study

Following are some ways to express a dissertation's delimitations:

• 1. Only those districts with student enrollments less than 1,000 were included in this study.

• 2. Those surveyed in this study consisted of female managers in their first supervisory position.

• 3. The study included only those organizations that matched the selection criteria established for the study. The criteria for selection included. …

Often the terms delimitation and limitation are confused. Mauch and Birch (1993) offered a clear distinction between the two. They stated, “A limitation is a factor that may or will affect the study in an important way, but is not under control of the researcher; a delimitation differs, principally, in that it is controlled by the researcher” (p. 103). Since limitations primarily involve the inherent weaknesses in the methodology, they are usually placed in the methodology section.

Assumptions

Not all studies include assumptions. Whether or not they are indicated depends on the desires of your advisor and committee members. Basically, assumptions are what you take for granted relative to your study. Following are some examples of assumptions:

• 1. The sample studied was representative of the total population of nurses employed at the St. Paul's Memorial Hospital.

• 2. Responses received from the participating managers accurately reflected their professional opinions.

• 3. High school students can remember what their perceptions were of the bilingual program in which they participated 10 to 12 years ago.

• 4. The participants in this study answered all of the interview questions openly and honestly.

Definition of Terms

This section of the dissertation provides the definition for the terms used that do not have a commonly known meaning or that have the possibility of being misunderstood. These terms should be operationally defined—that is, defined according to how the terms are used in your study. You can choose to define them in any way you like in order to clarify what you mean when you use that particular term. Unless they are clearly defined, they can be open to numerous interpretations. For example, the term achievement in education can refer to a variety of meanings. One operational definition may be the level of test scores throughout a school, or it could mean skill in playing the piano. It is appropriate to paraphrase or to specifically cite definitions used from the literature. Following are some examples of definition of terms used in dissertations:

Transformational leader. Someone in authority who articulates a clear vision for the future.

Empowerment. A process that enables people to do what they do best and for which they are held accountable.

Site-based management. A system that increases people's authority at the school site and involves them in implementing decisions.

Remember

Define each new term the first time it appears in the study.

Organization of the Study

Usually, Chapter 1 concludes with a section that delineates the contents of the remaining chapters in the study. Here is an example:

The remainder of the study is organized into five chapters, a bibliography, and appendixes in the following manner. Chapter 2 presents a review of the related literature dealing with evolving trends in the practices and procedures used to evaluate superintendents. Chapter 3 delineates the research design and methodology of the study. The instrument used to gather the data, the procedures followed, and determination of the sample selected for study are described. An analysis of the data and a discussion of the findings are presented in Chapter 4. Chapter 5 contains the summary, conclusions, and recommendations of the study. The study concludes with a bibliography and appendixes.

Summary

When writing your dissertation's introductory chapter, be sure to include background information to all the variables and concepts directly related to your study, the importance of your study to the field, and an explicit discussion of your study's conceptual or theoretical framework. Write a clear and succinct purpose statement and research questions that clearly define the parameters of your study. It is also important to include a delimitations section that clarifies the scope of your study and a definition of terms section that operationally defines the specific terms used in your study. A concluding statement delineates the contents of the study's remaining chapters.

The next chapter guides you through the process of selecting and describing your study's methodology.
