This role of theory has been characterized by YIN a as "analytic generalization" and has been contrasted with a different way of generalizing results, known as "statistical generalization" pp. Similarly, teaching case studies have become increasingly popular in science education.
YIN's two-part definition focuses on the scope, process, and methodological characteristics of case study research, emphasizing the nature of inquiry as being empirical, and the importance of context to the case. The psychologist, that will be good, for sure. Therefore they argue in favor of a theory-based category system, which is more open and can be changed during extraction when relevant information turns up but does not fit into the category system.
Yin 's guidelines and making positivist assumptions. The material is to be analyzed step by step, following rules of procedure, devising the material into content analytical units.
Quality criteria of reliability and validity see also Section 4. These are, to a differentiable degree, similar to the case study in that many contain reviews of the relevant literature of the topic discussed in the thorough examination of an array of cases published to fit the criterion of the report being presented.
From reviewing the description of methods, few authors provided a description or justification of case study methodology that demonstrated how their study was informed by the methodological literature that exists on this approach. References Adamson S, Holloway M. However, going into greater detail concerning these issues would be beyond the scope of this paper.
Case Study Research in Education: STAKEan educational psychologist with an interest in developing program evaluation methods, used a constructivist orientation to case study.
But even before that, different approaches to analysis and comparison of texts in hermeneutic contexts e. Bible interpretationsearly newspaper analysis, graphological procedures and even Freudian dream analysis can be seen as early precursors of content analysis MAYRING, a, . For instance, one can videotape the phenomenon or observe from behind one-way mirrors.
There is no single way to conduct a case study, and a combination of methods e.
Categories in the center of analysis: This mixed use of terminology is confusing given the definitional separations between methodology and methods and the varied application of case study in research endeavors.
Its development Section 4. Jones and Bartlett Publishers. Categories are understood as the more or less operational definitions of variables.
Researchers may study a single case or mutiple cases. The generalizations from teaching case studies also may relate to pedagogical issues rather than the substance of the case being studied.
In the 34 case studies reviewed, three described a theoretical framework informed by Staketwo by Yinand three provided a mixed framework informed by various authors, which might have included both Yin and Stake.
However, depending on the depth and range of the extant literature, the initial focus of the case study may be quite focused or broad and open-ended. Inter-subjective verifiability is a case in point here. As another fundamental characteristics he puts forth that "you do not start out with a priori theoretical notions" ibid.
Use of multiple sources of evidence; creation of a case study database; maintaining a chain of evidence. Methodological justification was insufficient in several of the studies reviewed Barone, ; Bronken et al. Verification of the specific instruments through pilot studies: The qualitative step of analysis consists of a methodologically controlled assignment of the category to a passage of text MAYRING, a, .
Exploratory or pilot case studies. First, a direct observer doesn't typically try to become a participant in the context. Determination of the material; analysis of the situation in which the text originated; the formal characterization of the material; determination of the direction of the analysis; theoretically informed differentiation of questions to be answered; selection of the analytical techniques summary, explication, structuring ; definition of the unit of analysis; analysis of the material summary, explication, structuring ; interpretation  Among the procedures of qualitative content analysis MAYRING a,  hallmarks the following two approaches as central to developing a category system and finding the appropriate text components as a result:.

Purposeful sampling is generally used in case study research; therefore, explain sampling procedures and case selection, and the defining characteristics and typicality or atypicality of the case: Note whether the case in question is a deviant or extreme case, a critical case, a convenience case, a politically significant case, and so on.
The case study as a type of qualitative research 29 Introduction Case studies were one of the first types of research to be used in the field of qualitative 1methodology.
There are a wide variety of methods that are common in qualitative measurement. In fact, the methods are largely limited by the imagination of the researcher. This course is designed to provide advanced graduate students with instruction in qualitative case study research approaches as applied to social science research.
The course will emphasize individual and group interviewing as techniques for qualitative case study data collection.Qualitative case study
