The fifteen contributions to this volume discuss current and future challenges for English language teaching from a wide range of different perspectives. The debate covered in this volume comprises a multitude of ELT-relevant theories ranging from cognitive linguistics, testing theory and communicative approaches to language learning to cultural studies, concepts of intercultural learning and current research in education. Specific attention is drawn to a variety of ELT topics that are relevant to the future - from traditional, subject-related concerns like grammar, vocabulary or pronunciation teaching to cultural dimension of ELT, impacts of the 'Common European Framework of Reference for Languages', the possibility of border-crossing in FL teacher training, 'Content and Language Integrated Learning' and teaching 'English as a Lingua Franca'.
