Tóm tắt	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.	Classic Grounded Theory (CGT) is a systematic qualitative methodology for generating substantive theory from empirical data. Developed by Barney Glaser and Anselm Strauss in 1967, it uses iterative cycles of data collection, constant comparison, and memo writing to produce a core category and surrounding conceptual framework that explains a social or psychological process. Unlike its later variants, Glaserian CGT insists on emergence — theory must arise from data without forcing preconceived frameworks.
