สรุป	Interpretive constructivist grounded theory is a qualitative research design in which the researcher and participants are understood as jointly constructing meaning, and theory is built inductively from data through systematic comparative analysis. Developed by Kathy Charmaz as a departure from the positivist assumptions of classic grounded theory, this approach situates both the researcher and participants as active interpreters whose social positions, values, and interactions shape the categories and theory that emerge from the study.	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.
