Tóm tắt	A field-based case study is a qualitative research design that investigates a bounded phenomenon — a case — within its real-world, natural setting through sustained on-site data collection. Combining the analytical structure of case study methodology with the direct observational immersion of fieldwork, it enables rich, context-sensitive understanding of how phenomena unfold in practice. The approach is firmly grounded in the frameworks of Robert Yin and Robert Stake and draws on anthropological traditions of participant and non-participant observation.	Field-based ethnography is a qualitative research design in which the researcher immerses themselves in a social setting or community over an extended period, observing and participating in everyday life to understand cultural practices, meanings, and social dynamics from an insider perspective. It is the classical form of ethnography, grounded in sustained physical presence at a research site, and distinguished from archival, virtual, or document-only approaches by its central reliance on direct, embodied fieldwork.
