Tóm tắt	Comparative multiple case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify patterns, contrasts, and transferable findings. Rooted in Robert Yin's case study methodology and Robert Stake's multiple-case analysis framework, it combines the rich contextual insight of single-case work with the analytical leverage gained by examining how phenomena unfold similarly or differently across distinct settings.	Comparative ethnography is a qualitative research design that conducts in-depth ethnographic fieldwork across two or more sites, groups, communities, or cultural settings in order to generate systematic comparisons. Rather than describing a single community in isolation, it traces similarities, differences, and interconnections across cases, producing theoretically grounded insights that no single site could yield alone.
