CLT is a learner-centered approach that emphasizes developing students' communicative competence. The goal is to use language for real communication purposes rather than just practicing grammar rules. Teachers act as facilitators who monitor students rather than controlling activities. Classroom activities like role-plays, interviews, and information gap exercises are used to encourage communication between students. However, CLT is not suitable for every context due to issues like large class sizes, varying student levels, and the need for teacher training and materials development to fully adopt this approach.
