The theory proposed by Teun A. Van Dijk is the most interesting and excessively used. He elaborates some elements of discourse so it could be used practically. According to Van Dijk (2004: 352) Critical discourse analysis (CDA) is: a type of discourse analytical research that primarily studies the way social power abuse, dominance, and inequality are enacted, reproduced, and resisted by text and talk in the social and political context. With such dissident research, critical discourse analysts take explicit position, and thus want to understand, expose, and ultimately resist social inequality.
The kinds of critical discourse analysis that he uses is often called as “Social Cognition”. He explains further that the study of discourse analysis is not adequate based on analysis on text since text is only the result of a production practice which must be perceived. Then, it also refers to see how the text is
produced, so the readers can understand why the products of a text as like that.
For example, there is a text that marginalized women, it is needed a research to see how the production’s process of text, why the text marginalized women.
