A clear, practical introduction to the theory and practice of translanguaging, this book explores this innovative approach and shows how English language teachers can benefit from implementing multilingual pedagogy in the classroom. Whether you teach English as a foreign language (EFL), a second language (ESL), work in English medium instruction (EMI) or Content and Language Integrated Learning (CLIL), this engaging and accessible book will help you understand the key implications of translanguaging theory, and carry these over into practice in your classroom, whether this is in government-sponsored or private education, from primary to secondary, tertiary and adult contexts. As well as discussing important contextual differences, challenges and constraints that teachers frequently face across both the Global North and Global South, it includes many examples from real English language classrooms, exploring both teacher and learner translanguaging, and offering numerous suggestions, ideas and activities to evaluate critically for your own classroom practice.
