概要	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.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.	Hermeneutic phenomenology is a qualitative research approach that investigates the interpreted meaning of lived experience from within the existential conditions that shape it. Rooted in Heidegger's ontology and developed as an empirical method by Max van Manen, it does not seek to bracket or suspend the researcher's understanding but instead treats that understanding as the very medium through which the meaning of experience can be disclosed. The approach is widely used in education, nursing, and social sciences to explore how people dwell in, and make sense of, their world.
