สรุป	An embedded case study is a case study design in which one or more units of analysis are nested within a single overarching case. Rather than treating the case as a single, holistic entity, the researcher deliberately examines multiple sub-units — such as departments within an organisation, classrooms within a school, or programmes within a hospital — to build a richer, more nuanced understanding of the phenomenon under study. Formalised by Robert K. Yin, the design is contrasted with the holistic single-case study and with multi-case (multiple-case) designs.	Action research is a collaborative research methodology in which researchers work with practitioners and community members to investigate a problem, implement change, and evaluate outcomes, cycling through reflection, action, and learning. Developed by Kurt Lewin (1946), action research bridges research and practice, aiming simultaneously to produce knowledge and practical improvement.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
