Muhtasari	Educational action research is a cyclical, practitioner-led inquiry method in which educators systematically investigate a problem or opportunity in their own classroom or school, implement a change, observe its effects, and reflect on findings to guide the next cycle. Rooted in Kurt Lewin's action research framework and developed for educational contexts by Lawrence Stenhouse and John Elliott, it bridges the gap between educational theory and classroom practice by making teachers agents of rigorous inquiry.	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.	Lesson study is a structured, cyclical form of professional development and educational research in which a team of teachers collaboratively plans a single 'research lesson,' observes it live in a classroom, analyzes student learning in detail, revises the lesson, and shares findings with the broader teaching community. Originating in Japanese elementary schools and brought to international attention by Stigler and Hiebert's 1999 comparative study, it has become one of the most widely adopted teacher-led inquiry methods worldwide.
