概要	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.	Multimodal Discourse Analysis is a method for examining how meaning is created through the integration of multiple modes of communication: language, image, sound, gesture, and spatial arrangement. Developed by Gunther Kress, Theo Van Leeuwen, and others, this approach recognizes that in contemporary communication—from videos to websites to classrooms—meaning is rarely conveyed by language alone. By analyzing how text, visuals, sound, and other modes work together, multimodal analysis reveals how complex meanings are constructed.
