概要	Autoethnography is a qualitative research method in which the researcher uses systematic self-reflection and personal narrative to examine their own experiences within a cultural, social, or organizational context. By treating the self as both subject and instrument, autoethnography connects individual lived experience to broader cultural patterns, making personal stories analytically and socially significant. It bridges autobiography and ethnography, producing accounts that are simultaneously evocative and scholarly.	Action research is a collaborative research methodology in which researchers work with practitioners and community members to investigate a problem, implement change, and evaluate outcomes, cycling through reflection, action, and learning. Developed by Kurt Lewin (1946), action research bridges research and practice, aiming simultaneously to produce knowledge and practical improvement.	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.
