This book deepens the insight into the setting and monitoring of language norms in different contexts. One focus lies on institutional contexts, in which the authors examine standardization, language policy and the implementation of usage norms. In the context of language learning, the authors investigate cognitive strategies of L2 norm construction by initial learners, L2 norms in grammars as well as interactional norms regulating teacher behavior. Finally, the volume theoretically explores the nature of discourse norms and examines their management and metadiscursive formulation in a variety of communicative activities and genres. Contributions to the volume are predominantly in English, some in German.
