CLL is an approach to language teaching where the teacher takes on the role of a counselor. It aims to make students feel comfortable in order to facilitate language learning. Teachers help students express themselves in the target language and structure class activities. Students are encouraged to interact, take responsibility for their learning, and learn from each other. The goal is for students to communicate in the language and learn about their own learning process. Key techniques include recording conversations, transcription, reflection, and group work.
