概要	Face-to-face participant observation is a qualitative data collection technique in which the researcher physically enters a setting and engages with participants in real time to document social behaviour, interactions, and meaning-making as they naturally occur. Unlike online or remote variants, the researcher is bodily present, enabling direct sensory access to context, non-verbal cues, and the full texture of everyday life in the setting under study.	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.
