This document summarizes a study that evaluated the effectiveness of the Communicative Language Teaching (CLT) approach compared to the traditional Grammar Translation Method (GTM) in teaching English in Pakistan. The study had two parts: 1) An experimental study that used pre- and post-tests to measure the achievement and attitudes of students taught with either CLT or GTM. The CLT group showed more improvement. 2) A survey of English teachers that identified challenges to implementing CLT, including issues with teachers, students, testing, and adapting Western approaches to local contexts. Overall, the study found CLT could be effective if implemented properly but faces barriers in the Pakistani education system and culture.
