CASE STUDY

HISTORY OF CASE STUDY

• As a distinct approach to research, use of the case study originated only in the early 20th century. The Oxford English Dictionary traces the phrase case study or case-study back as far as 1934, influenced by the much older concept of a case history in medicine.

• The use of case studies for the creation of new theory in social sciences has been further developed by the sociologists Barney Glaser and Anselm Strauss who presented their research method, Grounded theory, in 1967.

INTRODUCTION OF CASE STUDY

• Case study refers to the collection and presentation of detailed information about a particular participant or small group, frequently including the accounts of subjects themselves.

• Another suggestion is that case study should be defined as a research strategy, an empirical inquiry that investigates a phenomenon within its real-life context. Case study research means single and multiple case studies, can include quantitative evidence, relies on multiple sources of evidence and benefits from the prior development of theoretical propositions.

• Case study is used to gain in – depth understanding replete with meaning for the subject, focusing on process rather than outcome, on discovery rather than confirmation. The case study is the prefered strategy when, how, who, why, or what questions are being asked, or when thecontrol investigator has little control over events, or when the focus is on a contemporary phenomenon within a real life context.

DEFINITIONS OF CASE STUDY

• According to Bogdan and Bikien (1982 ) case study is a detail testing of certain problems.

• According to Surachrnad (1982 ) case study is an approach that focuses on an intensive and detail case.

• According Ary, Jacobs, dan Razavieh ( 1985 ), Case study is a research which the researcher tries to test an unit intensively and tries to find whole important variables.

CASE SELECTION

• Yin (2005) suggested that researchers should decide whether to do single-case or multiple-case studies and chose to keep the case holistic or have embedded sub-cases. This two-by-two combination can produce four basic designs for case studies.

• When selecting a case for a case study, researchers often use information-oriented sampling , as opposed to random sampling.

Three types of information-oriented cases may be

distinguished :

1. Extreme or deviant cases

2. Critical cases 3. Paradigmatic cases

Critical case

• A critical case can be defined as having strategic importance in relation to the general problem

CHARACTERISTIC OF CASE STUDY

The Characteristic of good case study :a. Concerning corker, related to public interest or even

with importance of national

b. Its boundary’s can be determined clearly, this equipment is also shown by and deepness broadness of data dug by researcher.

c. Can anticipate various answer alternative and viewpoint which different each other is

d.Case study can show just top-drawer evidence, both for supporting researcher view and also which do not base prince select vitas

e. Its result iss written with interesting style so that can communications at reader

Developing a Case Study

1. All data about the case is gathered.

2. Data is organized into an approach to highlight the focus of the study.

3. A case study narrative is developed.The narrative is a highly readable story that integrates and summarizes key information around the focus of the case study.

4. The narrative might be validated by review from program participants.

5. Case studies might be cross-compared to isolate any themes or patterns.

Design case study

Typically, research designs deal with at least four problems:

1. What questions to study

2. What data are relevant

3. What data to collect

4. How to analyze that data

However, Robert K. Yin (1993) does offer five basic components of a research design:

• A study's questions. • A study's propositions . • A study's units of analysis. • The logic linking of the data to the propositions. • The criteria for interpreting the findings

PURPOSES OF THE CASE STUDY

• There are some purposes of the case study are :• Firstly, they are very valuable as premliminaries

to major investigation. • secondly, observation case studies may have

the aim of probing deeply and analysing intensively the multifarious phenomena that constitute the life cycle of the unit, with a view to establishing generalisations about the wider population to which the units belong

• thirdly, a case study may provide anecdotal evidence that illustrates more general findings

• fourthly, a case study may refute a universal generalisation..

• fifthly, a case study is preferred when the relevant behaviours cannot be manipulated.

• finnaly, a case study may be valuable in its own right as a unique case.

TYPES OF CASE STUDY

• Historical case studies

• Observational case studies

• Oral history

• Situational analysis

• Clinical case studies

• Multi- case studies

PLANNING THE CASE STUDY

In case studies there are four main components to the research design :

1. Initial case study question

2. Study preposition

3. Unit of analysis

4. Linking Data
