概要	Participatory Lesson Study is an iterative, team-based professional development approach in which teachers — and often students, parents, or community members — jointly plan, observe, and critically reflect on live lessons to improve learning for a specific group of students. It extends the Japanese lesson study tradition by explicitly broadening participation beyond the teaching team to include diverse stakeholders, foregrounding equity, inclusion, and community perspectives in the inquiry cycle.	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.
