Tóm tắt	Field-based Straussian grounded theory applies the systematic coding procedures of Strauss and Corbin's grounded theory tradition to data generated through sustained fieldwork — direct observation, ethnographic notes, informal conversations, and artefact collection — rather than relying solely on formal interviews. The goal is to generate a substantive theory that is firmly anchored in the natural social setting where the phenomenon occurs, capturing both interaction and context.	Constructivist Grounded Theory (CGT) is a qualitative methodology developed by Kathy Charmaz that systematically builds mid-range theory from empirical data through iterative coding, memo-writing, and theoretical sampling. Unlike the original objectivist version by Glaser and Strauss, CGT treats both data and theory as co-constructed between researcher and participants, acknowledging the researcher's interpretive perspective as an integral part of the analytic process rather than a source of bias to be eliminated.
