  3. 3. DEFINITION• “A qualitative case study is an intensive, holistic description and analysis of a single instance, phenomenon or social unit” Merrian (1988).
  4. 4. • Case studies emphasize detailed contextual analysis of a limited number of events or conditions and their relationships
  5. 5. • If the phenomenon you are interested in studying is not intrinsically bounded, it is not a case.• We have to know how to finite the data collection.
  6. 6. STEPS TO FOLLOW• Determine and define the research questions• Select the cases and determine data gathering and analysis techniques• Prepare to collect the data• Collect data in the field• Evaluate and analyze the data• Prepare the report
  7. 7. Determine and define the research questions• The researcher establishes the focus of the study by forming questions about the situation or problem to be studied and determining a purpose for the study.
  8. 8. Select the cases and determine data gathering and analysis techniques• The researcher determines what approaches to use in selecting single or multiple real-life cases to examine in depth and which instruments and data gathering approaches to use.
  9. 9. Prepare to collect the data• Systematic organization of the data is important to prevent the researcher from becoming overwhelmed by the amount of data and to prevent the researcher from losing sight of the original research purpose and questions
  10. 10. Collect data in the field• The researcher must collect and store multiple sources of evidence comprehensively and systematically, in formats that can be referenced and sorted so that converging lines of inquiry and patterns can be uncovered.
  11. 11. Evaluate and analyze the data• Throughout the evaluation and analysis process, the researcher remains open to new opportunities and insights.
  12. 12. Prepare the report• The goal of the written report is to portray a complex problem in a way that conveys a vicarious experience to the reader.
  13. 13. QUALITATIVE CASE STUDIESParticularistic Heuristic Descriptive
  14. 14. Stake (1981)Case study knowledge is…• More concrete• More contextual• More developed by reader interpretation• Based more on reference populations determined by the reader
  15. 15. Reichardt and Cook (1979)Process as a focus for case study research can beviewed in two ways:• Monitoring: Describing, discovering, and providing feedback.• Casual explanation: Discovering or confirming.
  16. 16. Sanders (1981)• “Case studies help us to understand processes of events, projects, and programs and to discover context characteristics that will shed light on an issue or object” (p. 44).
  17. 17. Challenges• The researcher must identify his or her case.• Considering whether to study a single case or multiple cases.• Typically, the researcher chooses no more than four cases.
  18. 18. CONCLUSION A case study might be selected forits very uniqueness, for what it can reveal about a phenomenon, knowledge we would not otherwise have access to.
  19. 19. QUESTIONS TO REFLECT• What is the importance of cases studies in ELT?• What are the characteristics of a case study?
