概要	Participatory Discourse Analysis (PDA) integrates the collaborative ethos of participatory action research with the language-focused lens of discourse analysis. Community members or research participants are not merely sources of data — they are co-analysts who help collect, interpret, and act on discourse. PDA is used to uncover how language constructs power relations, identities, and social practices within marginalized or under-researched communities, and to translate those findings into concrete change.	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.
