概要	A participatory single case study is a qualitative design that examines one bounded case in depth while actively involving community members, practitioners, or participants as co-researchers throughout the inquiry. It blends Yin's case study rigor — triangulated evidence, thick description of context — with participatory action research values of collaboration, equity, and action. The result is both a rich, contextual understanding of the case and a knowledge-building process that serves the people within it.	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.
