สรุป	Interpretive case study is a qualitative research design in which the researcher selects a bounded real-world case — a person, program, event, organization, or community — and seeks to understand it from the inside, through the meanings participants themselves construct. Unlike explanatory or descriptive case study, the interpretive variant foregrounds the researcher's active role in making sense of complex, context-laden data rather than testing hypotheses or cataloguing facts.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.	Narrative inquiry is a qualitative research methodology that treats stories and life narratives as primary data, analyzing how individuals construct meaning and identity through storytelling. Developed by D. Jean Clandinin and F. Michael Connelly (2000), narrative inquiry examines the narratives people tell about their lives, experiences, and transitions, understanding that people make sense of experience through narrative.
