概要	Critical institutional ethnography (CIE) combines Dorothy Smith's institutional ethnography with an explicit critical theory lens to investigate how ruling relations, texts, and institutional discourses reproduce inequality and power asymmetries. Starting from the lived experiences of people positioned within or subordinated by institutions, CIE traces how abstract institutional processes coordinate everyday life and subjects those processes to normative critique aimed at social transformation.	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.
