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.	Classroom observation is a field research method in which a trained observer systematically watches, documents, and analyzes teaching and learning events as they occur in a real classroom setting. It can be structured (using a predefined coding instrument such as Flanders Interaction Analysis or CLASS), semi-structured, or open-ended (ethnographic notes), and is used across educational research, teacher professional development, school evaluation, and curriculum studies to generate ecologically valid evidence about instructional practice.
