สรุป	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.	Phenomenological research is a qualitative methodology focused on understanding the lived experience of a phenomenon as it is experienced by individuals. Rooted in the philosophical traditions of Edmund Husserl (descriptive phenomenology) and Martin Heidegger (interpretive phenomenology), this approach seeks to uncover the essential structures and meanings of human experience.
