Resum	Multiple-case lesson study extends the Japanese lesson study cycle — collaborative planning, live observation, and structured debrief of a single research lesson — across two or more independent cases (schools, classrooms, or teacher teams). By replicating and comparing the cycle at multiple sites, researchers can distinguish context-specific findings from those that generalize across settings, producing richer evidence about effective instructional practices in humanities and social science domains.	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.
