สรุป	Critical ethnography is a qualitative research approach that combines sustained fieldwork immersion with explicit critical theory to examine how power, inequality, and ideology shape the lived experiences of marginalised communities. Unlike conventional ethnography, which aims to describe a culture as it is, critical ethnography commits the researcher to questioning what is taken for granted and to producing knowledge that can serve as a resource for social change. Rooted in Frankfurt School critical theory and expanded through feminist, postcolonial, and race-critical traditions, it treats the research process itself as a political act.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.	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.
