สรุป	Intrinsic case study is a qualitative research method developed by Robert E. Stake in which a single, bounded case is studied in depth for its own inherent interest — not to illustrate a theory or to generalize, but because the case itself is unusual, revealing, or otherwise worthy of close attention. The researcher seeks a thick, holistic understanding of the particular: its context, its actors, its processes, and what makes it distinctively what it is.	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.
