สรุป	Field-based classic grounded theory applies Barney Glaser's original (Glaserian) grounded theory method within naturalistic, in-situ settings — combining sustained field immersion with the classic GT emphasis on emergence, theoretical sensitivity, and the constant comparative method. The researcher enters the social scene without a predetermined framework, collects data through observation and naturalistic interviews, and allows a substantive theory to surface inductively from the field rather than imposing conceptual structure in advance.	Field-based ethnography is a qualitative research design in which the researcher immerses themselves in a social setting or community over an extended period, observing and participating in everyday life to understand cultural practices, meanings, and social dynamics from an insider perspective. It is the classical form of ethnography, grounded in sustained physical presence at a research site, and distinguished from archival, virtual, or document-only approaches by its central reliance on direct, embodied fieldwork.
