摘要	A face-to-face focus group is a structured, moderated group discussion conducted in a shared physical space, typically with 6–10 participants who are selected because they share a relevant characteristic. The moderator follows a semi-structured topic guide to elicit opinions, perceptions, and experiences. Unlike surveys, focus groups capture social interaction — agreement, disagreement, and the group dynamics through which attitudes are formed and expressed.	Participant observation is a qualitative research method in which the researcher embeds themselves within a community, organization, or social setting for an extended period, engaging in the activities and relationships of the group while systematically observing and documenting behavior, interactions, and cultural meaning. Pioneered by Malinowski in the 1920s and developed in anthropology, the method has been adopted across sociology, education, health sciences, and organizational research. The researcher functions as both insider (participating in group activities) and outsider (maintaining analytical distance), generating thick description—rich accounts of context, behavior, and meaning that reveal how people actually live and interact.
