This paper introduces the information on the advantages and disadvantages of the case study approach. It discusses the type of research questions that can be addressed through the use of case studies, and explores some research methods.To start with, a case study can be considered to be a research design that allows the researchers to keep some integral characteristics of real events and episodes in the study of different empirical events.In turn, Flyvbjerg stated that “…a case and a case study cannot be of value in and of themselves; they need to be linked to hypotheses, following the well-known hypothetico-deductive model of explanation” (220).
The case study research has its major advantages and disadvantages. The main advantages include:
- Possibilities to explore some solutions for various complex issues or problems;
- Possibilities to develop different analytic skills that will help to solve some problems;
- Opportunities for students to utilize new and up-to-date skills and knowledge.
The main disadvantages are as follows:
- Inadequate information that may lead to some unsuitable and insufficient results;
- Inappropriate for the elementary level;
- It is impossible to see some relevance to your own situation.
Generally speaking, the case study research answers the questions that start with “why” or “how.” The main research object can be considered to be a person, a program or just a group of people. Each object is closely related to different issues, such as social, political, historical ones, etc.
To sum up, it is possible to say that there are two main research methods named a qualitative research method and a quantitative one. The expert interviews are related to qualitative research methods. The main difference between the qualitative methods and quantitative ones is that the data are collected from a relatively small group of respondents and are not analyzed with the help of statistics, while the quantitative methods are studied in a large group of people, and the data are analyzed using statistical methods.
