摘要:AbstractThis study examined the effectiveness in using media to enhance the level of critical literacy of tertiary students particularly in their EFL argumentative writing (N=46). Gains in the writing scores of the experimental group exposed to explicit instructional approaches of critical thinking were compared to those in the control group provided with imbedded instruction designed in their course materials. Results in the pretest and posttest demonstrated a significant difference (p<0.05). The findings suggest that the use of media and employment of explicit approaches in instructions had invariably enhanced students‟ writing performance to a great extent.
