概要	Participatory design-based research (PDBR) is an iterative educational research methodology in which practitioners — teachers, students, or community members — serve as genuine co-designers of interventions alongside researchers. Rooted in design-based research (DBR), PDBR adds explicit mechanisms for shared ownership, distributed decision-making, and practitioner voice across all design cycles, making it especially suited to developing contextually responsive educational solutions.	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.
