Tóm tắt	Field notes are detailed written records created by researchers during or immediately after direct observation in a naturalistic setting. They capture what is seen, heard, and experienced — including behaviors, interactions, physical environments, and the researcher's own analytic impressions — forming the primary data source for ethnographic and observational studies.	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.
