This book looks particularly at the relationship between language, interaction and learning. Providing a comprehensive account of current perspectives on classroom discourse, the book aims to promote a fuller understanding of interaction, regarded as being central to effective teaching and introduces the concept of classroom interactional competence (CIC). The case is made in this book for a need not only to describe classroom discourse, but to ensure that teachers and learners develop the kind of interactional competence which will result in more engaged, dynamic classrooms where learners are actively involved in the learning process. This approach makes an invaluable resource for language teachers, as well as students of language and education, and language acquisition within the field of applied linguistics.
