Tóm tắt	Field-based constructivist grounded theory integrates Kathy Charmaz's constructivist grounded theory with active fieldwork in natural settings. Rather than relying solely on retrospective interviews, the researcher enters the participants' world — observing, interacting, and collecting data where social processes unfold — while simultaneously coding and building theory. The result is a grounded substantive theory that is both empirically anchored in real contexts and epistemologically co-constructed between researcher and participants.	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.
