In language learning contexts, the role of the language teacher is a particularly crucial one: it is the teacher who, through and with their use of (the foreign) language, has a significant influence on the extent to which language learners are linguistically/cognitively activated, and thus determines whether processes of language learning are initiated and promoted, or perhaps even impeded or prevented. Thus, it is of utmost importance for language teachers to acquire a high level of classroom discourse competence (CDC) - a professional competence that goes far beyond the notions of FL proficiency and communicative competence. Located at the intersection of theory, classroom research and practical approaches to (E)FL teacher education, Classroom Discourse Competence: Current Issues in Language Teaching and Teacher Education offers university students, trainee teachers, in-service teachers and teacher educators a comprehensive conceptualization of CDC (Part I). Furthermore, the chapters in this book explore facets of CDC (Part II) and present good-practice examples of CDC development in the context of pre-service teacher education (Part III).
