Providing a series of chapters, written by teacher educators in three continents, this edited volume explores the concepts, challenges, possibilities, and implementations of competency-based instruction for developing English competencies in English as a foreign language (EFL) contexts. Recent trends in education have emphasized the need to develop competencies that connect learning with real-life performances. This need has brought about a massive increase in the number of studies and scholarly works devoted to research into competency-based education. However, for teachers and learners of EFL, it is challenging to develop competencies for using a language that does not seem to connect with their real-life scenarios. The chapters apply the concept of competency-based instruction in different EFL contexts and are structured around three themes: Theory: current thoughts on theories of competency-based education Research: empirical research on competency-based teacher education Practice: integrating competency-based instruction into teacher education This book offers examples of competency-based EFL teacher education through both research and practical applications. In addition to the innovation in competency approaches, the inclusion of language learning in virtual environments offers a valuable resource for scholars, educators, researchers, and all those concerned with current and future education.
