This document discusses the Communicative Language Teaching (CLT) approach. It provides background on how CLT emerged in the 1970s with a focus on communicative proficiency over grammatical structures. Key principles of CLT are that the goal is effective communication, the teacher facilitates and students actively communicate. Activities include information gap tasks, role plays, and simulations. While CLT has advantages like interaction and enjoyment, criticisms note the difficulties in implementation and student needs/interests.
