Using a “storytelling” approach, the evaluator may present the genesis of ideas, explore what happened and why, give an account of the human side of a project, explain goals, explore project dynamics, investigate particular phenomenon, and present outcomes in their complexity without being subject to the confines inherent in most other evaluation methods.The freedom to collect multiple kinds of information makes the case study method useful for exploring ideas and constructing theories about program or project dynamics.
With this procedure it is assumed that one can acquire knowledge of the phenomenon studied from intense exploration of a single case.
Besides the medical and psychological, it became a major methods of qualitative research in human and social sciences.
For example, the case study can be exploratory (create new knowledge), constructive (solve some problem), or confirmatory (test a hypothesis with empirical evidence).
The case study can also use either a primary (the researcher collects the data) or secondary (the researcher uses someone else’s data) approach.
He states, “In general, case studies are the preferred strategy when ‘how’ or ‘why’ questions are being posed, when the investigator has little control over events, and when the focus is on a contemporary phenomenon within some real-life context.” (Yin 1994 p.1) One of the biggest disadvantages to using the case study method has to do with external vs. Using the case study method, the researcher often does not have control over certain variables and events and, therefore, cannot control them as the researcher could in a lab experiment Consequently, the researcher using the case study method must be content that his/her findings may only be applicable to similar cases.
What the case study gains in internal validity, it loses in external validity.You can view samples of our professional work here.Any opinions, findings, conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of UK Essays.Some of the criticism against case studies in this area relate to single-case studies.However, that criticism is directed at the statistical and not the analytical generalization that is the basis of case studies.Despite its advantages, the case study method is traditionally considered to have several major limitations as an evaluation tool.Descriptive case studies are qualitative and unreliable.” (Yin, 1994) Among the possible explanations Yin considers are that people are not trained in the use of other methods, or, for governmentally sponsored research, that the difficult permission procedures required for surveys and questionnaires have made their use “a bureaucratically hazardous affair,” leading researchers to the case study method, which is relatively unencumbered by restrictions and requirements.Identifying three types of case studies ââ‚¬” descriptive, exploratory, and explanatory, Yin argues that the case study method qualifies as a serious research tool.Yin proposed three remedies to counteract this: using multiple sources of evidence, establishing a chain of evidence, and having a draft case study report reviewed by key informants.Internal validity is a concern only in causal (explanatory) cases.
