The document discusses the importance of reducing teacher talk (TTT) in the classroom. It notes that while teacher talk can be useful for clarifying concepts and explaining grammar, relying too heavily on it limits student-to-student talk, makes the students' role passive, and hinders the development of their speaking skills. The document provides strategies for lesson designs and activities that encourage more student participation and interaction, such as assigning pair and group work, using elicitation instead of explanation, and having students give feedback to one another.
