Methods of Qualitative Observational Research

Qualitative observational research involves more than simply going out into the field and observing a given group or culture. Researchers must also consider such issues as their role, their research question, the theory driving their inquiry, how they will collect and analyze information, and how they will report their results. In this section, we address these issues in detail. We also consider the use of multiple methodologies for collecting information and the role of computer software in qualitative observational research.

Steps and Methods used in Qualitative Observational Research

Qualitative observational research involves more than simply going out into the field and observing a given group or culture. Researchers must also consider the following:

Observer's role
As Connelly and Clandinin (1990) point out, in all instances, qualitative observational research involves formulating a thoughtful and well-understood relationship between the researcher and research participants. It is essential for the researcher to determine what role(s) to play to ensure facilitation of the study and acceptance by the participants in the study group or culture. Some possibilities include observing-participant, participant-observer and neutral observer.

The observer's role is to record group interactions and behaviors as objectively as possible using various qualitative inquiry tools. Observing-participants already have a position in the society/community before taking on the role of observer. They must also examine their own subjectivity and consider that participating in the group might lead to sympathetic or antagonistic interpretations of group behaviors. Participant-observers, on the other hand, attempt to become part of community and to adopt roles as participants, but come to the study with their own culture or community inscriptions. They attempt to participate fully and take on participant roles, but must be careful to behave in a consistent manner as part of the setting so as not to cause significant changes in the community itself. Although neutral observers do not participate in the group they are studying, they still need to be aware of any presumptions they may hold that would influence their findings and what influence the act of observing the participants may have on their behavior.

It is the observer's responsibility to let readers of the research report know not only the role played in the research, but also the point of view of the observer.

Defining the research question
Unlike most scientific research methods, qualitative observational inquiry does not require the researcher to define a precise set of issues in the initial phases; these issues often emerge from the study over time. While some qualitative inquiries may begin with a set of questions, it is common for theories about group behavior and interactions to emerge as a result of the observer's exploratory work (emergent design). And, those theories may identify relevant questions for further research.

The goal of qualitative observational research is to define and answer a specific research problem or question, but this problem or question may or may not be defined at the time when the researcher first begins the study. Some researchers like to enter the field with a specific research problem already in mind. While such researchers still want to let events unfold as freely as possible once in the field, they believe that by defining the research problem in advance they are better able to observe the study group or culture and identify specific patterns of behavior.

Other qualitative observational researchers like to enter the field first and let the research questions or problems identify themselves. These researchers believe that entering the field with a specifically defined research question may bias their observations, and they may fail to notice relationships or behavior patterns that are important in understanding the study group or culture. Whatever approach is taken in determining the research question, the observer does need to be clear about the purpose, scope, and focus of the study and identify the subjects and the context in which they will be studied.

Identifying the theory that drives the inquiry
The qualitative observational researcher must determine what underlying theory or model should inform the research. This may mean replicating or building on an earlier study, or it may mean formulating a new model or theory by which to conduct the study. Either way, the theory or model chosen will help the researcher determine how to structure the study (i.e., whether to study participants in the classroom only or to study them outside of the classroom as well, and how and when to use interviews).

Selecting qualitative research tools
Selecting how and when data will be collected is an essential step in designing qualitative observational research studies. One of the primary tools of ethnographic study is the use of field notes. Observers may simply begin with a blank notebook and write down everything that goes on. Others may use audio and/or video tapes. Some observers begin with a list of categories of behavior to be noted. This works best when the research question is already defined; however, categories should be flexible and modifiable throughout the study.

The goals of note taking are to help ensure validity of the data collection and interpretation processes, to check data with members of context if possible, to weigh the evidence, and to check for researcher and subjects' effects on both patterned and outlying data.

Another useful tool, journal records, may be made by participants, researchers or practitioners. These records are collected through participant observation in a shared practical setting.

Written dialogue between researcher and participants is also used in narrative inquiry as a way of offering and responding to tentative narrative interpretations (Clandinin, 1986). Researchers may look at autobiographical and biographical writing, as well as documents such as plans, newsletters, course materials and student products, rules, laws, architecture, picturing, metaphors, poetry, clothing, foods, rituals, physical setting, and implements such as musical instruments, artifacts, logs--in short, anything within the context of the studied group that speaks of their experience.

Unstructured interviews may be used to collect data; personal stories tell us something of how group members perceive and experience their conditions. Structured interviews permit more focused information gathering, but may overlook aspects of the group that an unstructured interview might reveal. To facilitate truthful responses, the interview should be informal or conversational in nature. Interviewees may be selected with intent to uncover specific information or to gain a cross section of group members (for instance, both high achievers and those having difficultly with the material).

Researchers may need to use "stimulation recall" to prompt interviewees or participants in informal discussion concerning specific events. Another method, "simulation response," presents hypothetical situations to obtain responses from members of the community. While these methods are often helpful, they are not infallible. Members may inhibit access to information by concealing aspects of their lives or by telling researchers what they think they want to hear.

Analyzing and reporting data

The final steps to be taken by the qualitative observational researcher are analyzing the data and writing the research report. The researcher's work culminates in synthesizing and interpreting the data into an understandable and enlightening piece of writing. But, despite the fact that these steps mark the culmination of the researcher's work, it should not be assumed that they are reserved for the end of the study. Instead, it is common for the researcher to analyze data and write parts of the final report throughout the research process. In analyzing descriptive data, the researcher reviews what was witnessed and recorded, and synthesizes it with the observations and words of the participants themselves.

The observer begins with reading a situation as a text, applying as many critical techniques as possible without violating the sanctity of the text. It is important to avoid picking and choosing instances of behavior out of context. Analysis may reveal convergent data, metaphors that run throughout a language, culture, or group (thematic analysis). Key terms or key metaphors may be unpacked and examined for their significance and interrelationships among other aspects of group dynamics (content analysis). Dominant plots in the literature, films, and the text of daily life of the group aid in analysis of the data as a whole.

Writing the research report

You can read a brief description of each of these areas by clicking on the items in the list above. It is important to note that the order of presentation is not indicative of an essential or set pattern. Although some elements in the researcher's decision-making process will necessarily precede others (i.e., the determination of the researcher's role before data collection), most of the steps outlined below will significantly overlap and recur throughout the research process.

Employing Multiple Methods

It is important to underscore that one cannot point to a single clear definition of a qualitative study. Oftentimes researchers triangulate data by combining different types of qualitative approaches and even including quantitative elements. For example, Doheny-Farina (1985) conducted a study of the collaborative writing process in a new software company. He visited the company for three to five days a week over eight months. His visits ranged from one to eight hours. His key informants were the company's top five executives, two middle managers, and two outside consults. He took 400 pages of field notes of three types: observational, theoretical, and methodological. He tape-recorded meetings, and he also conducted 30 open-ended and discourse-based interviews.

Doheny-Farina analyzed the data by reviewing it chronologically and developing a coding scheme as he reviewed. From the data he discovered a major theme and sub-theme. His analysis describes the writing of the company's business plan within its organizational context.

Essentially, his data showed that the organizational context shaped the writing of the business plan while the writing of the business plan shaped the organizational context.

Although the article Doheny-Farina wrote about his study starts out much like a traditional research report, it reports its results as a story with a chronology and a discussion of themes. He also offers theoretical, pedagogical, and research implications. He concludes by allowing that he is offering a model that is not necessarily generalizable but nonetheless valuable.

Computer Software for Qualitative Observational Research

Qualitative observational research, by nature, involves the compilation of massive amounts of data. Because of this, many researchers have begun using computer software to help them organize and make sense of the volumes of information. There are many reasons for using computers in qualitative research, but according to Richards and Richards (1993), "Computers [offer] to address each of the obvious barriers to qualitative analysis by manual methods--limitations on size, flexibility and complexity of data records, and systems of theorizing about data." The authors also argue that using computers for qualitative research can give studies more credibility and status because of the association between computers and "hard" data. Research software can also help the researcher to analyze data that was previously too unwieldy for study. Finally, computers greatly speed up the process of retrieving and exploring data. In their text Computer Programs for Qualitative Analysis, Weitzman and Miles (1995), cite a list of the ways computer software can help the qualitative researcher (p. 5):

Making notes in the field
Writing up or transcribing field notes
Editing: correcting, extending, or revising field notes
Coding: attaching keywords or tags to segments of text to permit later retrieval
Storage: keeping text in an organized database
Search and retrieval: locating relevant segments of texts and making them available for inspection
Data "linking": connecting relevant data segments to each other, forming categories, clusters, or networks of information
Memoing: writing reflective commentaries on some aspect of the data as a basis for deeper understanding
Content analysis: counting frequencies, sequence, or locations of words and phrases
Data display: placing selected or reduced data in a condensed organized format, such as a matrix or network, for inspection
Conclusion-drawing and verification: aiding the analyst in interpreting displayed data and testing findings
Theory-building: developing systematic, conceptually coherent explanations of findings; testing hypotheses
Graphic mapping: creating diagrams that depict findings or theories
Preparing interim and final reports
Before choosing software for a qualitative study, researchers should not only be familiar with the types of software available, but they should also be well versed in the particular program functions and features they need. Flexibility and user friendliness are two more considerations addressed by Weitzman and Miles. They explain that before choosing software, researchers should find out if the software is designed to do what they need, and if not, can the software be adapted to meet the needs of a particular study. In addition, researchers should consider how complicated the software is to learn and use. Researchers should also find out if the software comes with a manual, has on-screen help, and/or has a technical support phone number.
