สรุป	Face-to-face participant observation is a qualitative data collection technique in which the researcher physically enters a setting and engages with participants in real time to document social behaviour, interactions, and meaning-making as they naturally occur. Unlike online or remote variants, the researcher is bodily present, enabling direct sensory access to context, non-verbal cues, and the full texture of everyday life in the setting under study.	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.
