This document summarizes research on approaches to teaching critical thinking in English for Academic Purposes (EAP) writing classes. It finds that critical thinking involves skills like analysis, evaluation and argument construction. Studies show EAP students struggle with critical thinking due to perceiving it as criticism, difficulty finding their voice, and linguistic demands. Effective approaches embed critical thinking in discipline-specific contexts, use collaboration, and clarify expectations of critical thinking. Teachers should allow time to discuss interpretations and consider content and cultural backgrounds.
