This study aims to inspect several literacy discourses and to deploy the critical literacy discourse. Literacy education must bring up the subject possessing the critical literacy. Critical literacy means 'the ability to interpret the given discourse critically, and to produce one's own discourse which can reconstruct the society and oneself'. But literacy discourses, till now, have been negligent of the 'critical' aspect of the literacy education.
The procedures of the study are as following : first, to analyze the ideologies which enable the given literacy discourses, second, to analyze the mechanism of the given literacy discourses of excluding the critical literacy, third, to illuminate and expand the critical literacy discourses.
The given several literacy discourses share the premises of objective ideology and interactive ideology. Objective ideology premises that the truth and the knowledge exist independently outside the subject and can be identified by the experience. The literacy discourses possessing the premises of objective ideology consider non-dialectically the relation of the language, the subject, and the reality. And they call the literacy education which exclude the important context such as power, ideology etc., and select the mechanical and functional approach.
Interactive ideology dissents the objective ideology and considers the interaction of the subject and the text importantly. But interactive ideology can't construct the critical literacy because it considers the authority of meaning attributes to discourse community not to individual subject.
To illuminate the critical literacy, this study spotlights the literacy discourses such as post-modernism, critical pedagogy, cultural studies. These discourses are hoped for the theoretical resources in deconstructing the objective, interactive ideologies and designing the critical literacy discourse. They emphasis 'reading ideology', 'reading deconstructively', 'producing different genre', etc.. These strategies will be the important elements in the critical literacy education.
