How to Use Case Study in Education Dissertation Research

A case study is a qualitative (and sometimes mixed-methods) research approach used in education dissertations to explore a specific educational “case” in depth within its real-world context. Instead of focusing on broad generalizations, case study research helps researchers understand how and why educational processes, programs, or experiences work in a particular setting.

In education research, a case study might focus on a school, classroom, program, teacher group, or student cohort.

In simple terms, a case study asks: “How and why does this specific educational setting, program, or group function the way it does?”

What Is a Case Study in Education Research?

In education, a case study is an in-depth investigation of a bounded system, such as:

• A school or district

• A classroom or cohort

• A specific educational program (e.g., online learning program)

• A teaching strategy implementation

• A curriculum reform initiative

It uses multiple sources of data to develop a rich, contextual understanding of educational practice and experience.

Key idea:

Case studies prioritize depth and context over generalization.

When Should You Use a Case Study in an Education Dissertation?

You should use a case study when your research focuses on:

• Real-world teaching and learning environments

• Educational programs or interventions

• Classroom practices and pedagogy

• Policy implementation in schools or institutions

• Complex educational systems

Example research questions:

• How is a new literacy program implemented in an elementary school?

• Why do students engage differently in an online learning environment?

• How does a school support first-generation college students?

Case studies are especially useful in K–12 education, higher education, and instructional design research.

Types of Case Study Designs in Education

1. Single Case Study

Focuses on one educational case in depth.

Used when:

• The case is unique or highly illustrative

• The goal is deep understanding of one setting

Example:

A single university’s implementation of hybrid learning.

2. Multiple Case Study

Examines two or more cases for comparison.

Used to:

• Compare educational settings

• Identify patterns across schools or programs

Example:

Comparing student engagement strategies in two online universities.

3. Intrinsic Case Study

Focus:

• The case itself is the primary interest

• Not designed to generalize findings

4. Instrumental Case Study

Focus:

• The case is used to understand a broader educational issue

• Helps explain theory or practice beyond the case

Step-by-Step: How to Use Case Study in an Education Dissertation

Step 1: Define the Educational Case

Clearly identify:

• What the case is

• Where it is located

• Who is involved

• Time frame of the study

Example:

“This case study examined the implementation of an online learning program in a U.S. public high school during the 2025 academic year.”

Step 2: Develop Case Study Research Questions

Case study questions focus on how and why educational processes occur.

Example:

• How do teachers implement project-based learning in the classroom?

• Why do students respond differently to blended learning strategies?

Avoid:

• Purely quantitative questions like “Does this program improve test scores?”

Step 3: Select the Case and Participants

Cases are selected using purposive sampling, based on relevance.

Participants may include:

• Teachers

• Students

• Administrators

• Support staff

Sample size is usually small to allow for depth.

Step 4: Collect Multiple Sources of Educational Data

A strong case study uses data triangulation.

Common data sources:

• Interviews with teachers and students

• Classroom observations

• Curriculum documents

• Student performance records

• Surveys or reflections

• School policy documents

Step 5: Analyze the Case Data

Case study analysis focuses on identifying patterns and meaning within the case.

Common methods:

• Thematic analysis

• Pattern matching

• Cross-data synthesis

• Narrative analysis

Process:

• Organize data by source

• Identify recurring themes

• Compare perspectives (teachers, students, administrators)

• Build a coherent explanation of the case

Step 6: Develop a Rich Description of the Case

The result should be a thick, detailed description of the educational setting.

This includes:

• Context of the school or program

• Key participants

• Teaching and learning processes

• Institutional structures

• Key findings and themes

Example:

“The school’s success with blended learning was driven by strong teacher collaboration, consistent technology access, and structured student support systems.”

Step 7: Ensure Trustworthiness

Instead of validity and reliability, case study research uses:

• Credibility (accuracy of findings)

• Dependability (consistency of methods)

• Confirmability (minimizing researcher bias)

• Transferability (applicability to other settings)

Techniques include:

• Triangulation of data sources

• Member checking

• Audit trails

• Reflexive journaling

Step 8: Connect Findings to Educational Theory

Link results to frameworks such as:

• Constructivist Learning Theory

• Social Learning Theory (Bandura)

• Experiential Learning Theory (Kolb)

• Transformative Learning Theory (Mezirow)

This strengthens the academic contribution of the dissertation.

Common Mistakes in Education Case Study Research

Avoid:

• Defining the case too broadly

• Using only one data source

• Treating case studies like surveys

• Weak justification for case selection

• Lack of contextual detail

• Overgeneralizing findings

Strengths of Case Study in Education Research

• Provides deep insight into real educational settings

• Captures complexity of teaching and learning

• Useful for program evaluation and policy research

• Supports practical educational improvements

• Flexible and data-rich

Limitations of Case Study in Education

• Limited generalizability

• Time-intensive data collection

• Requires strong organization of multiple data sources

• Potential researcher bias if not carefully managed

Final Thoughts on How to Use Case Study in Education Dissertation Research

Case study research is a powerful approach in education dissertation research for exploring real-world teaching, learning, and institutional practices in depth. It allows researchers to understand not just what is happening in educational settings, but how and why it happens in context.

A strong case study dissertation is well-bounded, deeply contextual, evidence-rich, and theoretically informed, offering meaningful insights for educational practice and policy.
