Résumé	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.	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.	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.
