Discuss the importance of the purpose statement in any research and distinguish between the purpose statement and the problem statement in a research. 2.Sele

Use words such as purpose, intent, study aim, or objective to signal attention to this statement as the central controlling idea. Set the statement off as a separate sentence or paragraph, and use the language of research, such as “The purpose (or intent or objective) of this study is (was) (will be) . . .” Researchers often use the present or past verb tense in journal articles and dissertations and the future tense in proposals because researchers are presenting a proposal for a study not yet undertaken.

Focus on a single phenomenon (or concept or idea). Narrow the study to one idea to be explored or understood. This focus means that a purpose does not convey relating two or more variables or comparing two or more groups, as is typically found in quantitative research. Instead, advance a single phenomenon, recognizing that the study may evolve into an exploration of relationships or comparisons among ideas. None of these related explorations could be anticipated at the beginning. For example, a project might begin by exploring teacher identity and the marginalization of this identity in a particular school (Huber & Whelan, 1999), the meaning of baseball culture in a study of the work and talk of stadium employees (Trujillo, 1992), or how individuals cognitively represent AIDS (Anderson & Spencer, 2002). These examples illustrate a focus on a single idea.

Use action verbs to convey how learning will take place. Action verbs and phrases, such as, understand, develop, explore, examine the meaning of, generate, or discover, keep the inquiry open and convey an emerging design.

Use neutral words and phrases—nondirectional language—such as, exploring the “self-expression experiences of individuals” rather than the “successful self-expression of individuals.” Other words and phrases that may be problematic include useful, positive, and informing—all words that suggest a directional outcome that may or may not occur. McCracken (1988) referred to the need in qualitative interviews to let the respondent describe his or her experience. Interviewers (or purpose statement writers) can easily violate the “law of nondirection” (McCracken, 1988, p. 21) in qualitative research by using words that suggest a directional orientation.

Provide a general working definition of the central phenomenon or idea, especially if the phenomenon is a term that is not typically understood by a broad audience. Consistent with the rhetoric of qualitative research, this definition is not rigid and set but tentative and evolving throughout a study based on information from participants. Hence, a writer might say, “A tentative definition at this time for ___________ (central phenomenon) is . . .” It should also be noted that this definition is not to be confused with the detailed definition of terms section as discussed in Chapter 2 on the review of the literature. The intent here is to convey to readers at an early stage in a proposal or research study a general sense of the central phenomenon so that they can better understand the types of questions and responses asked of participants and data sources.

Include words denoting the strategy of inquiry to be used in data collection, analysis, and the process of research, such as whether the study will use an ethnographic, grounded theory, case study, phenomenological, narrative approach, or some other strategy.

Mention the participants in the study, such as one or more individuals, a group of people, or an entire organization.

Identify the site for the research, such as homes, classrooms, organizations, programs, or events. Describe this site in enough detail so that the reader knows exactly where a study will take place.

As a final thought in the purpose statement, include some language that delimits the scope of participation or research sites in the study. For example, the study may be limited to women or Latinas only. The research site may be limited to one metropolitan city or to one small geographic area. The central phenomenon may be limited to individuals in business organizations who participate in creative teams. These delimitations help to further define the parameters of the research study.

Although considerable variation exists in the inclusion of these points in purpose statements, a good dissertation or thesis proposal should contain many of them.

To assist you, here is a script that should be helpful in drafting a complete statement. A script, as used in this book, contains the major words and ideas of a statement and provides space for the researcher to insert information.

The purpose (or study aim) of this ___________ (strategy of inquiry, such as ethnography, case study, or other type) study is (was? will be?) to ___________ (understand? explore? develop? generate? discover?) the ___________ (central phenomenon being studied) for ___________ (the participants, such as the individual, groups, organization) at ___________ (research site). At this stage in the research, the ___________ (central phenomenon being studied) will be generally defined as ___________ (provide a general definition).

Examples 6.1–6.4 may not illustrate perfectly all the elements of this script, but they represent adequate models to study and emulate.

Example 6.1A Purpose Statement in a Qualitative Phenomenology Study

Lauterbach (1993) studied five women who had each lost a baby in late pregnancy and their memories and experiences of this loss. Her purpose statement was as follows:
