Tóm tắt	A research diary is a systematic, dated log maintained by the researcher throughout a study to record methodological decisions, emergent observations, analytical hunches, and reflections on researcher positionality. Unlike a participant diary, it is authored by the researcher and functions simultaneously as a data source, an audit trail, and a reflexivity instrument.	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.
