Tóm tắt	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.	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.
