概要	Visual elicitation single case study is a qualitative design that embeds photo or image elicitation techniques within a bounded, in-depth investigation of a single case — a person, community, program, or event. Photographs, drawings, or participant-produced images are introduced into interviews to prompt richer, more vivid accounts than verbal questioning alone can generate, while the single case study frame provides the disciplined contextual analysis needed to understand the case as a whole.	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.
