摘要	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.	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.	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.
