概要	Critical Discourse Analysis (CDA) is a qualitative method that examines how language in texts and talk constructs, sustains, and challenges relations of power, ideology, and social inequality. Drawing on linguistics, social theory, and critical philosophy, CDA treats discourse not merely as communication but as social practice — a site where dominance is reproduced and where resistance can be articulated. Developed in the late twentieth century by Norman Fairclough, Teun van Dijk, and Ruth Wodak, among others, CDA is applied to political speeches, media texts, policy documents, educational materials, and institutional interactions.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.
