Tóm tắt	A Triangulated Research Diary is a qualitative data collection approach in which a researcher's ongoing reflective diary is used as one strand within a triangulated data collection strategy. The diary records observations, decisions, emotions, and emerging interpretations across the study, while at least one other data source — such as interviews, documents, or observations — is collected in parallel. Cross-checking diary entries against other sources increases the credibility and depth of the findings.	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.
