This edited volume presents an inter- and multidisciplinary approach towards language teacher education, confronting the issues that have continued to  pervade the field for the last two decades. Featuring contributions from researchers and teacher educators located within a truly international spread of countries - Mexico, Palestine, Tunisia, Cyprus, and Kuwait to name a few - chapters adopt an ecologically glocalised approach to understand how English language teaching is theorised and practised in different educational contexts across the world. Research gathered from interviews, meta-analysis, and international case studies is showcased as chapters consider both pedagogical and online issues within, as well as critical approaches to, language teacher education. Professional development and evaluation programmes across different educational contexts are discussed in-depth along with guidance and insights for the future of the field. The book will be of interest to scholars, researchers, and postgraduate students working in the fields of English language teacher education, TESOL, applied linguistics, continuing professional development.
