Ringkasan	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.	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.
