Tóm tắt	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.	In-depth interviews are a qualitative research method in which a trained interviewer conducts one-on-one conversations with individual participants using open-ended questions to explore their experiences, perspectives, and understandings of a phenomenon. Developed in the 1950s by Rogers and Hyman, the method varies along a spectrum from structured (standardized question sets) to semi-structured (guided topic areas with flexibility) to unstructured (emergent, conversational). In-depth interviews are widely used in sociology, psychology, health sciences, anthropology, and organizational research to capture rich, detailed narratives and personal meaning.
