সারসংক্ষেপ	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.	Design-based research (DBR) is an iterative, interventionist methodology that simultaneously designs educational interventions and builds theory about how and why those interventions work in authentic, complex settings. Originating in Ann Brown's 1992 classroom experiments and Allan Collins's parallel work, DBR treats the learning environment as both the object of study and the site of theory generation, cycling through design, enactment, analysis, and redesign until both practical improvement and theoretical insight are achieved.
