Description

Creswell and Poth (2018) define case study as a strategy that involves the study of an issue explored through one or more cases within a bounded system (i.e., a setting or a context), a methodology, a type of design in qualitative research, or an object of study, as well as a product of the inquiry.

Flyvbjerg (2011) defines case study as an intensive analysis of an individual unit (as a person or community) stressing developmental factors in relation to the environment. Case study methodology aims to describe one or more cases in depth. It examines how something may be occurring in a given case or cases and typically uses multiple data sources to gather information. Creswell and Poth also argue that the use of different sources of information is to provide depth to the case description. Case study methodology aims to describe one or more cases in depth. It examines how something may be occurring in a given case or cases and typically uses multiple data sources to gather the information. This is the first step of data analysis in a qualitative case study. Following this, researchers must decide whether there is a case study to analyze, determine the boundaries of their case study and its context, decide whether they wish to use single or multiple case studies, and explore approaches to analyzing themes and articulating findings. Creswell and Poth (2018) are an ideal resource for defining case study, learning about its parts, and executing case study methodology.

The authors are both recognized academics in the field of qualitative research; Dr. Creswell has authored many articles and 26 books on topics such as mixed-methods research, qualitative research, and research design, and Dr. Poth has written more than 30 peer reviewed journal articles and was a guest co-editor at the International Journal of Qualitative Methods. The book thoroughly reviews and compares five qualitative and inquiry designs, including research, phenomenological research, grounded theory research, ethnographic research, and case study research. Chapter 4, which is titled Five Qualitative Approaches, gives a thorough description and explanation of what a case study research contemplates. It discusses its definition and origins, its features, the types of case study procedures to follow when doing a case study, and the challenges faced during case study development. In the appendix, on page 119, the authors offer an example of a case study and a question that can be used for discussion. The entire book has pertinent information for both novice and experienced researchers in qualitative research. It covers all parts of the research process, from posing a framework to data collection, data analysis, and writing up.

Clapp, F. N. (2017). Teachers’ and researchers’ beliefs of learning and the use of learning progressions (Doctoral dissertation). Retrieved from ProQuest Dissertations & Theses Global. (Order Number 10261732)

This study from Colorado State University was designed to identify the beliefs and discourse that both the Learning Progressions (LP) developers and the intended LP implementers held around student learning, teaching, and learning progressions. The study’s research questions were examined through the use of an instrumental case study. The researchers were deliberate in applying theory and study phenomena in their context, as it investigated teachers’ practices in the context of their respective classrooms.

Applying theory to the study phenomena, this study provided insight into the relationship between LP models and teachers’ perceptions about how students learn content in a particular context. The data was collected using interviews with teachers who participated in a year-long teacher-in-residence program. Researchers and content experts who conceptualized the LP were also interviewed to study the impact that it had on participants’ perceptions of the LP and any teacher reported changes in their respective classrooms. The findings of this study inform literature on both science teacher professional development and LP’s theory to practice.

This study from Georgia State University answered the following questions: 1) How does a secondary mainstream teacher experience the phenomenon of the inclusion of ELLs in a mainstream content area classroom? 2) How do ELLs experience the phenomenon of inclusion within the secondary mainstream content area classrooms? 3) How do the points of interaction between the secondary mainstream teacher, the English language learners, the content and the context shape the experiences of the inclusive classroom?

To comprehend the socio-constructivist learning theory which guided the design of this study, one must begin with understanding the epistemological stance of constructionism. Constructionism is seated within an interpretivist paradigm which asserts that reality does exist outside the realm of human interpretation; rather, it is human interpretation which makes meaning of this reality. The researcher applied Denzin and Lincoln’s (2004) bricoleur approach to this study, as it offered them the opportunity “to piece together a set of representations that is fitted to the specifics of this complex situation in an overlapping series of events” (p. 4). The researcher stated that his worldview shaped his research questions which called for a single case study research design.

Smith, P. H. (2000). Community as resource for minority language learning: A case study of Spanish-English dual-language schooling (Doctoral dissertation). Retrieved from ProQuest Dissertations & Theses Global. (Order Number 304578045)

The author studied a school where a dual language (Spanish- English) program was being developed. He focused on the role of the community and the students’ acquisition of Spanish. Through a case study design, his theoretical framework was contemplated under the fields of language planning, language revitalization, and funds of knowledge. The author believed that minority language (Spanish) acquisition could be supported by incorporating local language resources, and in this way undermine the strong influence of the English language. To analyze his data, he went through a triangulation process of participant observation in classrooms, literacy instruction, teacher, parent and community interviews, and document and archival analysis. Findings showed that minority language resources are less often incorporated in the curriculum than those of the language majority. Thus the study suggested that these types of programs should include the funds of knowledge and available resources of the language minority communities.

Graham R Gibbs. (2012, October 24). Types of Case Study. Part 1 on Case Studies. Retrieved from https://youtu.be/gQfoq7c4UE4

The first part of this series is an attempt to define case studies. Dr. Gibbs argued that it is a contemporary study of one person, one event, or one company. This contemporary phenomenon cab be studied in its social life context by using multiple sources of evidence.

When completing a case study, we either examine what affects our case and what effect it has on others, or we study the relationship between “the case” and between the other factors. In a typical case study approach,  you choose one site to do your work and then you collect information by talking to people, using observations, interviews, or focus groups at that location. Case study is typically descriptive, meaning “you write what you see”, but it could also be exploratory or explanatory.

Types of Case Study:

1. Individual case study: One single person
2. Set of individual case studies: Looking at three single practices
3. Community studies: Many people in one community
4. Social group studies: The case representing social phenomenon “how something is defined in a social position”
5. Studies of organizations and institutions: The study of “election, ford, or fielding”
6. Studies of events, roles, and relationships: Family relationships

Graham R Gibbs. (2012, October 24). Planning a case study. Part 2 on Case Studies. Retrieved from https://youtu.be/o1JEtXkFAr4

The second part of this series explains how to plan a case study. Dr. Gibbs argues that when planning to conduct a case study, we should think about the conceptual framework, research questions, research design, sampling/replication strategy, methods and instruments, and analysis of data.

For any type of research, a good source of inspiration could be either from personal experiences or from talking with people about a certain topic that we can adopt.

The Conceptual Framework: Displays the important features of a case study; shows the relationships between the features; makes assumptions explicit; is selective, iterative, and based on theory; takes account of previous research; includes personal orientations, and includes overlap and inconsistency.

Research questions should:

1. Be consistent with your conceptual framework.
2. Cover conceptual framework.
3. Be structured and focused.
4. Be answerable.
5. Form a basis for data collection.

In the final part of the three videos of case study, Dr. Gibbs examines case study designs and variations that are possible. He also discusses replication strategies which help give the studies reliability and test to see if they can be generalized. Dr. Gibbs highlights the methods and instruments used, how to analyze the data, and concludes with problems of validity you may encounter and common pitfalls of case study research. In summary, case studies can involve gathering a lot of data and you can start analyzing the data while collecting and going through it.

In this short video (1.49 min.), three kinds of case studies (exploratory, descriptive, and explanatory) are described, as well as rationales for using them. These rationales are as follows:

1. Exploratory: If you know nothing about the case.
2. Descriptive: When you write what you see, you are describing the situation.
3. Explanatory: When you try to understand why things are happening, then you explain them.
