Tóm tắt	Critical digital ethnography is a qualitative research design that combines the immersive, participatory observation of digital ethnography with the power-conscious, emancipatory orientation of critical theory. Researchers embed themselves in online communities, platforms, or digital practices and examine not only what people do online but also how digital spaces reproduce, challenge, or transform structures of power, inequality, and identity. It is widely used in education, communication studies, and social science.	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.
