概要	Critical thematic analysis (CTA) is a qualitative approach that combines the systematic coding procedures of Braun and Clarke's thematic analysis with the interrogative stance of critical theory. Rather than merely describing patterns in data, CTA asks whose interests those patterns serve, what power relations they reflect, and what is absent or silenced. It is used to surface ideology, structural inequality, and hegemonic assumptions embedded in participants' accounts or in texts.	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.
