Definition of the Case Study
A qualitative research approach in whichresearchers focus on a unit of studyknown asabounded system (eg: individual teachers, aclassroom , a school).
To study a phenomenon.

Example: Asmussen, K.J., & Creswell, J. W. (1995). Campus response
to a student gunman. Journal of Higher Education, 66(5), 575-591.
This case study describes a campus response to a gunman incident inwhich a student attempted to fire a gun at his classmates. The studyprovides a detailed description of the gunman incident; a chronologyof the first 2 weeks of events following the incident; and details about
the city, the campus, and the building in which the incident occurred.Finding s resulting from data collection through multiple sources ofinformation, such as interviews, observations, documents, andaudiovisual materials, are presented. From the data analysis, denial,fear, safety, retriggering, and campus planning emerge as prominent
concerns. These themes are combined into two overarchingperspectives, an organizational and a psychological or social-psychological response, providing layers of analysis in the studyand broader interpretations of the meaning of the case. The authorssuggest that campuses plan their responses to campus violence andadvance key questions to be addressed when preparing these plans.

When to Use the Case Study?
To answer a descriptivequestion, whathappened or an explanatoryquestion,
how or why did something happen?
Interested in studying process
To understand phenomena

Characteristics of Case Study
Particularistic :Focus on a particular phenomenon(eg:situation/event)
Descriptive :The end result of the case study, the narrative,include thick description of the phenomenon thatwas the focus of the case study research.
Heuristic :Case studies illuminates the readers understandingof the phenomenon under study beyond the
readers original knowledge.

Characteristics of Case Study
Different disciplinary fields use case studyresearch for different purposes, and specificcharacteristics of the study are determined by
the discipline.
Example of disciplines:
* Historical case study
* Sociological (collective behaviour of groups)

Case study research design
Includes:
1.A statement of the purpose of the research
2.Initial research questions3.Review of related literature
4.A rationale for the selection of the case

Case study research design cont.
The case study researcher should:
1.Determine the research questions
who, what, how and why provide the case.2.Define the case under the study
- similar to defining variables in quantitativeresearch.
3.Determine the role of theory development in caseselection - make explicit the theoretical orconceptual frameworks that supports the choice ofparticipants.

4. Determine the theoretical or conceptualframework of the study attend to the literature related to yourresearch interest.
5. Determine whether a single case study, amultiple case studyor a collective case studyisappropriate.

Sample selection in
case study research Select a small number of individuals who can
help to understand the investigated phenomenon.
The researcher needs to select the unit of analysis a child, a classroom of children or an entireschool district.
The most common form of sampling is purposiveor purposeful sampling due to information richor learn a great deal about the research problem.

Sample selection incase study research cont.
Another consideration in selecting a case theviability of the case.
It should be done through screening procedure to avoid problems associated with selecting acase. Eg. Participants withdraw from the case.

Sample selection in
case study research cont.
Ascreening procedure steps:
1.Reviewdocuments about the proposed case
study site.2.Conduct informal interviews of key participants.
3.Determine whether the participants have the
necessary experience and knowledge ofinvestigated phenomenon and the ability toprovide information.

In educational research, it is common tofind case study research undertaken aboutone phenomenon but at multiple sites.
This is also known as collective casestudies, multicase or multisite studies orcomparative case studies.
Multiple case studies require cross-site
analysis

An unordered meta-matrix is a datamanagement tool that enables the case studyresearcher to assemble master charts withdescriptive data from each site on one largesheet of paper.
UNORDERED META-MATRIX

Sites are ordered on a variable of interest sothat the researcher can see the differences.
The researcher can see differences betweenhigh, medium, and low sites

Moves the case study researcher from workingdescriptively/deductively to a moreexplanatory/interpretive mode.
Allow the researchers to understand the
variables that appear to contribute most directlyto the outcomes.
SITE-ORDERED PREDICTOR-OUTCOME MATRIX

Extends the cross-site analysis to includechronology as an organizing variable.
Time highlights the critical aspect of data.

SCATTERPLOTS
Scatterplots are visual displaysof data from all the case studysites based on dimensions orthemes of interest that appear to
be related to each other.
Hence the researcher may seethe clustering of themes,
occuring trends.

SITE ORDERED EFFECTS MATRIX
To sort through the research sites and todisplay probable cause-and-effect relations.
Eg: The action & the outcomes of the study.

CAUSAL MODELS
Extends the case study analysis and assist thecase study researcher to identify how thingsgo together.
