This book provides an overview of current trends and practices in English Language Teaching (ELT) across the European Union. It offers insights into key ELT issues which are at the forefront of twenty-first-century classrooms. It discusses theoretical and empirical work based on topics such as linguistic imperialism, English as a Medium of Instruction, contrastive language analysis, and the interplay between English and the use of countries' respective native languages. It also explores the challenges of English Language Teaching under different circumstances such as, while using different technological platforms, working with different learner groups (those with Special Educational Needs) and revising traditional practices in grammar and vocabulary teaching. Throughout the book, the link between policy, theory and practice is explicitly highlighted and exemplified. The book is of interest to ELT instructors, course designers, language teachers and teacher trainers, and students enrolled in pre-service English training courses.
