Case studies can be useful for generating new research questions, for studying rare phenomena, and for illustrating general principles. Case study research has a long history within the natural sciences, social sciences, and humanities, dating back to the early 1920's. A case study research paper usually examines a single subject of analysis, but case study papers can also be designed as a comparative investigation that shows relationships between two or more subjects.

The research approach and design of the study is discussed in terms of the methodological contribution. The case study is the comprehensive study of one or very few research subjects, allowing obtaining a broad and detailed knowledge of the latter. Evidence arising from multiple-case studies is often stronger and more reliable than from single-case research. The use of past studies allows additional information without needing to spend more time and money on additional studies. There are several different definitions and kinds of case studies.

Intervention studies selected for this review targeted skill acquisition as the dependent variable and used (a) at least one school-age participant with little to no functional vision, (b) a response-prompting procedure from one of the categories described by Wolery and Gast (1984) or SP, and (c) a single-case experimental design. Consider the following: An embedded case study is a case study containing more than one sub-unit of analysis (Yin, 2003). Opener. Opener. This review considers master protocols, which involve the study of one or more interventions in multiple diseases or of a single disease with multiple interventions. Using a multiple-case research study allows for a more in-depth understanding of the cases as a unit, through comparison of similarities and differences of the individual cases embedded within the quintain.

Another point that single-subject researchers make is that group researchers also face a similar problem when they study a single situation and then generalize their results to other situations. Menu. It will further answer the benefits and disadvantages with the different types. Then the literature review is discussed and analysed to reach a conclusion. Single-case experimental designs (SCED) are experimental designs aiming at testing the effect of an intervention using a small number of patients (typically one to three), using repeated measurements, sequential (± randomized) introduction of an intervention and method-specific data analysis, including visual analysis and specific statistics. 4 0 obj stream ABSTRACT There are several different definitions and kinds of case studies. In a single-subject… This study attempts to answer when to write a single case study and when to write a multiple case study. For example, researchers who conduct a study on the effect of cell phone use on drivers on a closed oval track probably want to apply their results to drivers in many other real-world driving situations. Single-subject designs are quite popular because they are very flexible and highlight individual differences in response to treatment/intervention. Research design (Yin/COSMOS Corp., 1984), Research purpose. This study attempts to answer when to write a single case study and when to write a multiple case study.

I'm a grad student and having trouble finding good sources that explain when you should use a single case study approach versus a multiple-case study approach. Similar to a case study, an embedded case study methodology provides a means of integrating quantitative and qualitative methods into a single research study (Scholz & Tietje, 2002; Yin 2003).However, the identification of sub-units allows for a more detailed level of inquiry. The single case study is the most basic form of case-oriented research, but researchers may also conduct a series of case studies, each study building on the previous, or conduct simultaneous studies of several instances of the same phenomenon (as in comparative research).

Case study design (2/2) Generally multiple- case study preferred over single- case study, for these offer robust analytical conclusions (increases external validity) Multiple- case study design When external conditions are not thought to produce much variance in the phenomenon being studied, a smaller number of theoretical replication is needed. For two, case studies look at the history of a person, whereas single-subject design looks at the effects of treatment in one person and then compares it to others. single-subject approach should not be confused with the case-study or case-history approach where a single individual is also studied exhaustively. Case study typologies 6 1. Multiple-Case Designs If the same study contains more than a single case, it is a multiple-case design Advantages Evidence is considered more compelling Overall study is therefore regarded as more robust Disadvantages Rationale for single-case designs usually cannot be satisfied by multiple cases Can require extensive resources and time There are several different definitions and kinds of case studies.

Single Case Versus Multiple Case Another design characteristic of a case study is whether the design is single case or multiple case. This series of four experiments sought to assess the comparative effects of multiple- versus single-ratio schedules on a pupil's responding to mathematics materials. The case-study approach is often an uncontrolled inquiry into history (retrospective) and it may yield interesting information. After all, a sample case study report can provide you with some context so you can see how to approach each aspect of your paper. Similar to a case study, an embedded case study methodology provides a means of integrating quantitative and qualitative methods into a single research study (Scholz & Tietje, 2002; Yin 2003).However, the identification of sub-units allows for a more detailed level of inquiry. Es gibt Rollen für Mitwirkende und es wird eine Situation oder ein (Problem-)Fall angenommen, in der bzw. 5. Another explanation of this unclear status is that the case study is often defined as the study of one single case, rather than as a way of doing research (Verschuren, 2003). Evidence arising from multiple-case studies is often stronger and more reliable than from single-case research. So overall, case studies and single case designs are two different kinds of experiment design that use individuals as subjects. The primary focus of these multiple- case studies was to determine how information can be managed to facilitate the WIL process for various faculties at a higher education institution.
