สรุป	Visual Elicitation Critical Discourse Analysis (VECDA) is a qualitative methodology that uses photographs, drawings, or other visual materials as prompts to elicit participant talk, then subjects both the visual artifacts and the resulting discourse to critical discourse analysis (CDA). The approach uncovers how power, ideology, and social structures are reproduced or contested through the interplay of image and language, making it particularly powerful for social justice, health, education, and media research.	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.
