概要	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.	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.	Curriculum analysis is a systematic research method for examining the content, structure, goals, and underlying assumptions of educational curricula — including written syllabi, textbooks, lesson plans, and policy documents. By mapping what is taught, how it is sequenced, and what values are embedded, researchers and educators can evaluate alignment with learning objectives, identify gaps or biases, and guide curriculum reform across all levels of education.
