The document summarizes a study on teachers' perceptions and practices regarding Communicative Language Teaching (CLT) at a junior high school in Batam, Indonesia. The study found that while teachers understood CLT principles, their classroom practices did not fully align due to factors like large class sizes, an exam-focused system, and lack of time. Specifically, teachers saw value in CLT's focus on communication over accuracy and student-centered approach. However, their ability to implement these principles was limited by classroom realities. The mismatch between perceptions and practices showed CLT was not being properly implemented due to constraints in the educational system and classroom environment.
