For any pre- or in-service mainstream teacher learning how to teach the English Language Learners or world language students in their classrooms--or those who simply want to get better at it--here is an interactive approach that's packed with engaging features, opportunities for reflection, important new ideas and suggestions, and a number of ways to better connect to professional development standards like the Common Core Standards and WIDA. Content-Based Second Language Teaching and Learning gives readers opportunities to interact with the material; reflect and consult with colleagues, partners, and classrooms; revisit their responses; and get assistance from accompanying PowerPoint presentations online that focus on the key concepts of each chapter. Packed with practical, how-to ideas and techniques culled from two critical fields of study--psycholinguistics and socio-cultural--it offers today's teachers more methodological approaches to teaching in ESL settings than virtually any other book on the market.
