This new addition to the Routledge Handbooks series is one of its most adventurous. Not only does this volume cover an impressively wide range of themes both conceptual and practical, including some topics rarely if ever treated previously, but its contributors come from a broad range of geographical and scholarly backgrounds. The volume’s extensive diversity thus ensures its substantial relevance to linguistics researchers and students right around the globe.Jennifer Jenkins, University of Southampton, UKThis wonderfully comprehensive Handbook is essential reading for all those who wish or need to know anything, something, or indeed everything about the theories and practices connected with the development and teaching of English as an international language. It will become the benchmark publication in the field.Andy Kirkpatrick, Griffith University, AustraliaSpanning from theoretical foundations to classroom methodologies, this seminal handbook provides a systematic and insightful overview of EIL education, with contributions from leading scholars in the field. This is truly an epoch-making publication, as the first comprehensive coverage of TEIL half a century after the birth of the concept of EIL.Nobuyuki Hino, Osaka University & Otemon Gakuin University, Japan
