The contributions to this volume explore several focal issues related to the global spread of English and their implications for English language teaching, providing both theoretical and empirical perspectives on recent research and implications in educational terms. The volume is divided into three thematic sections, namely "Developments in ELF research and pedagogic implications", "Raising teachers' awareness of ELF", and "ELF and ELT practices".The book provides up-to-date perspectives on the issues, implications and repercussions that findings in ELF research can have for ELT practices. The contributors are all scholars and researchers who have long been engaged in ELF-related research, and who have undertaken operational and practical work in the field, and, as such, offer novel perspectives on the effects of EFL research on the teaching and learning of English. The volume also presents the findings of innovative projects in teacher education, involving pre- and in-service teachers, providing exemplificative good practices of possible new routes into pluralistic, ELF-aware and ELF-oriented didactic perspectives.
