Tóm tắt	Focused ethnography is a condensed, problem-centred variant of classical ethnography in which a researcher with prior domain knowledge enters a specific social setting for a bounded period — typically days to weeks rather than months or years — to study one clearly defined issue or practice. Developed as a response to the time and resource constraints of applied research, it is widely used in healthcare, organisational studies, and professional education, where the researcher's existing familiarity with the setting allows rapid, targeted data collection without sacrificing ethnographic depth.	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.
