Classroom language has not yet been recognized as an important aspect of foreign language learning and teaching, but it can make a meaningful contribution to language instruction. Providing for teacher training in this field not only implies provision of information and practice, but also involves changing teacher attitudes about the appropriateness of certain areas of reference for foreign language classroom discourse. Teaching styles and methods would probably also be affected by incorporation of classroom language study. Although there are large areas of overlap between general and classroom-related aspects of teachers' language, classroom language provides a less arbitrary and possibly more helpful framework for examining language learning activities in teacher education. Research can build on some recent advances in the conceptualization of classroom language and its importance in learning and teaching. (MSE)
