สรุป	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.	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.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
