概要	Digital Critical Discourse Analysis (Digital CDA) is a qualitative research approach that applies the theoretical and methodological tools of Critical Discourse Analysis to digital and online communicative contexts. It examines how language, multimodal elements, and digital affordances are mobilized in online spaces to produce, reproduce, or contest power relations, ideologies, and social inequalities. Drawing on traditions established by Fairclough, Wodak, and van Dijk, Digital CDA treats digital texts — from social media posts to comment threads and websites — as sites of ideological struggle shaped by the platforms that host them.	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.
