Tóm tắt	Mobile Field Notes is a data collection technique in which researchers use smartphones, tablets, or wearable devices to record observations, reflections, photographs, audio, or video in real time during fieldwork. By capturing data at the moment and place of occurrence, the method reduces recall bias and enables richer, contextually anchored documentation compared with traditional pen-and-paper notes written retrospectively.	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.
