Unveiling the Power of Case Studies: Examples and Applications

Case studies stand as a cornerstone of research and education, offering a deep dive into specific instances, scenarios, or individuals. They serve as invaluable tools for exploring complex phenomena, testing theories, and informing real-world decisions across diverse fields. This article explores the essence of case study methodology, its applications, and provides illustrative examples to guide students and researchers alike.

Understanding Case Study Methodology

Case study methodology is both unique and uniquely confusing. The term "case study" can refer to the methodology itself-a system of frameworks for designing a study-or to the methods used to conduct the study. It can also describe a type of academic writing that delves into a problem, process, or situation.

At its core, case study methodology involves the study of one or more "cases," which can be instances, examples, or settings where a problem or phenomenon can be examined. The researcher defines the parameters of the case, determining what is included and excluded, a process known as bounding the case. Case study methodology can be combined with other methodologies like ethnography, grounded theory, or phenomenology to further define the study and refine the approach.

Case study research is conducted across various social science disciplines, including business, education, sociology, and psychology. Its reliance on multiple data sources makes it a natural choice for interdisciplinary studies.

The Purpose of Case Study Research

The purpose of case study research is twofold:

To provide descriptive information.
To suggest theoretical relevance.

Rich description enables an in-depth or sharpened understanding of the case. What makes case studies unique is that they draw from more than one data source. They are inherently multimodal or mixed methods, using more than one form of data within a research paradigm or from different paradigms.

A case study inquiry could include multiple types of data:

Multiple forms of quantitative data sources, such as Big Data + a survey.
Multiple forms of qualitative data sources, such as interviews + observations + documents.
Multiple forms of quantitative and qualitative data sources, such as surveys + interviews.

Types of Case Studies

Robert Yin, a prominent methodologist, differentiates between descriptive, exploratory, and explanatory case studies:

Descriptive: A case study whose purpose is to describe a phenomenon.
Explanatory: A case study whose purpose is to explain how or why some condition came to be, or why some sequence of events occurred or did not occur.
Exploratory: A case study whose purpose is to identify the research questions or procedures to be used in a subsequent study.

Case Study Examples Across Disciplines

Case study methods are employed in qualitative, quantitative, and mixed methods research. Here are some examples across different subjects:

Education

Ang, C.-S., Lee, K.-F., & Dipolog-Ubanan, G. F. (2019) conducted a quantitative case study to determine the determinants of first-year student identity and satisfaction in higher education. The study analyzed data collected from 554 first-year undergraduates at a large private university using the Melbourne Centre for the Study of Higher Education Survey. The results indicated that students' reasons for pursuing tertiary education were primarily to open doors to career opportunities and skill development. Student engagement explained more variance in student identity, while students’ expectations and experience explained greater variance in students’ overall course satisfaction.

Urban Studies and Musicology

Baker, A. J. (2017) assessed how mathematical flowcharts, such as Algorithm A (Economics), Algorithm B (Four T’s creative index), and Algorithm C (Heritage), have contributed to the definition of a music city. Taking Melbourne as a case study, it illustrates how Algorithms A and B are used as disputed evidence about whether the city is touted as Australia’s music capital. The article connects the three algorithms to an academic framework from musicology, urban studies, cultural economics, and sociology, and proposes a benchmark Algorithm D (Music Cities definition), which offers a more holistic assessment of music activity in any urban context.

Political Science

Brown, K., & Mondon, A. (2020) explored the mainstreaming of the far right through the lens of populism and media coverage. Using The Guardian newspaper as a case study, the authors employed a mixed-methods approach to discourse analysis. The study argued that the common conflation of populism with far-right politics has contributed to the mainstreaming of the far right through agenda-setting power and deflection, euphemisation and trivialisation, and amplification.

Sociology

Droy, L. T., Goodwin, J., & O’Connor, H. (2020) presented a case-study of a multi-strategy analysis, applied to the problem of estimating the long-term impact of 1980s UK government-sponsored youth training. The study highlighted the problem of cumulative methodological fragilities in applied quantitative sociology and to discuss and help develop multi-strategy analysis as a tool to address them.

Management

Ebneyamini, S., & Sadeghi Moghadam, M. R. (2018) reviewed the use of case study research for both practical and theoretical issues especially in management field with the emphasis on management of technology and innovation. This study represents a general structure to guide, design, and fulfill a case study research with levels and steps necessary for researchers to use in their research.

International Relations

Lai, D., & Roccu, R. (2019) introduced and adapts the extended case methodology as a critical, reflexivist approach to case study research, whereby the case is constructed through a dynamic interaction with theory, rather than selected, and knowledge is produced through extensions rather than generalisation. Its potential is illustrated in the final part of the article with reference to researching the socioeconomic dimension of transitional justice in Bosnia and Herzegovina.

Library and Information Science

Lynch, R., Young, J. C., Boakye-Achampong, S., Jowaisas, C., Sam, J., & Norlander, B. (2020) presented qualitative and quantitative evidence from 23 African countries involved in a crowdsourcing project to map libraries. The authors find benefits in terms of increased connections between stakeholders, capacity-building, and increased local visibility. These findings demonstrate the potential of crowdsourced approaches for tasks such as mapping to benefit libraries and similarly positioned institutions in the Global South in multifaceted ways.

Social Work

Mason, W., Morris, K., Webb, C., Daniels, B., Featherstone, B., Bywaters, P., Mirza, N., Hooper, J., Brady, G., Bunting, L., & Scourfield, J. (2020) detailed the application and integration of mixed methods throughout all stages of one such project; a study of child welfare inequalities. By offering a critical discussion of site selection and the management of confirmatory, expansionary and discordant data, this article contributes to the limited body of mixed methods exemplars specific to this field. We propose that our mixed methods approach provided distinctive insights into a complex social problem, offering expanded understandings of the relationship between poverty, child abuse, and neglect.

Business Discipline

Rashid, Y., Rashid, A., Warraich, M. A., Sabir, S. S., & Waseem, A. (2019) presented a systematic step-by-step guide to conduct a case study in the business discipline. This article presents a checklist comprised of four phases, that is, foundation phase, prefield phase, field phase, and reporting phase. The objective of this article is to provide novice researchers with practical application of this checklist by linking all its four phases with the authors’ experiences and learning from recently conducted in-depth multiple case studies in the organizations of New Zealand.

Case Studies in Education: Engaging Students and Fostering Active Learning

Case studies can be powerful tools in education, promoting student engagement and active learning. Professor Jeremiah Johnson at the School of Natural Resources and Environment, University of Michigan, integrated case studies into his course, NRE 615: Renewable Electricity and the Grid.

Student-Created Case Studies

Professor Johnson, feeling dissatisfied with relying so heavily on lectures and the passivity it encouraged among students, had his students create their own case studies as the major project for the course. The initiators of the proposal had chosen case studies because they have been shown to enhance student learning.

MSC's Role

MSC (Michigan Sustainability Cases) representatives joined the class to scout for the best ideas to potentially fund and develop into complete, multimedia-enriched cases. Later, Professor Johnson found himself in MSC’s first curricular advisors meeting, reviewing proposals with other faculty from around campus. By the end of the two-hour meeting, 27 proposals had been accepted and would become the very first MSCs, including two proposals from his students in NRE 615.

"Distributed Energy Storage": A Case Study Example

One of the case studies, “Distributed Energy Storage” (Kraus et al., 2016), focused on an innovative partnership between Tesla and Green Mountain Power, a small electric utility in Vermont. The team chose to do the majority of the podcast production themselves. One of the student case authors, Andrea Kraus, had some experience in audio production, and she was using this opportunity to flex and strengthen her media muscles. The podcast was shaping up to be an excellent addition to the case study, both as a complementary mode of learning and as a connection to the practitioner for the case, Josh Castonguay of Green Mountain Power.

Assessing the Impact of Case Studies

Professor Johnson assessed the case by giving his students a quiz with content-related questions about the case. The students would see these same questions on the final exam, and he planned to compare scores between the two tests.

Results and Observations

Professor Johnson’s assessment results were encouraging: Most students showed improvement from pre- to post-test, including international and first-generation college students. Interestingly, the Engineering students showed the largest score gains, followed by the SEAS and Business students. Overall, Professor Johnson told the audience, he had observed great value in having students write a teaching case.

Case Studies for Fostering Empathy and Problem-Solving Skills

Case studies can also be used to foster empathy and problem-solving skills in students. Sophia A. developed several case studies that place students in real-world scenarios, challenging them to think critically and creatively.

Bachiko's Story: A Celebration of Culture and Compassion

In one case study, students are introduced to Bachiko, a little girl from Japan who will be joining their class after the earthquake. The class plans a celebration for her, incorporating elements of Japanese culture to help her feel welcome. The students are prompted to consider how they would feel if they were far from home on their birthday and to learn about Japanese culture.

Jorge's Dilemma: Protecting the Amazon Rainforest

Another case study tells the story of Jorge, a 13-year-old from Brazil who lives in the Amazon and whose community is threatened by deforestation. Students are challenged to put themselves in Jorge's place and devise a plan to protect the trees his family needs. The rainforest is important to everyone’s heath-but few people know that or care. Talk about environmental issues. Ask them about what they do to help conserve the planet’s resources. Ask them to think about how environmental issues link people across the globe.

Mia's Mission: Addressing the Landmine Crisis in Angola

In a third case study, students learn about Mia, a 16-year-old from Angola whose brother lost both legs in a landmine explosion. Students are challenged to imagine how Mia might solve the problem of landmines in her community and raise awareness about the issue globally.

Essential Components of an Academic Case Study

When constructing an academic case study, it's important to ensure that it is thorough and structured. Key components include:

Title Page: Clearly indicates the subject of the case study.
Abstract: Provides a concise summary of the case, its objectives, and key findings.
Introduction: Sets the context and introduces the problem or issue being examined.
Literature Review: Provides background information and relevant theories related to the case.
