概要	Face-to-face field notes are a foundational qualitative data collection technique in which the researcher is physically present in the setting and records observations, interactions, events, and contextual details in written form. As the canonical mode of ethnographic and observational research, in-person field notes capture the social texture, nonverbal cues, spatial arrangements, and moment-to-moment dynamics of real-world settings that remote or mediated data collection cannot fully replicate.	Non-participant observation is a data-collection method in which the researcher observes behavior, interactions, or events in a natural or structured setting without joining or influencing the activity under study. The observer maintains a deliberate distance from participants to minimize their own effect on the phenomena being recorded, producing field notes, behavioral tallies, or recordings that reflect naturally occurring behavior rather than behavior shaped by researcher involvement.
