What English Teachers Need to Know, a set of companion texts designed for pre-service teachers and teachers new to the field of ELT, addresses the key question: What do English language teachers need to know and be able to do in order for their students to learn English? These texts work for teachers across different contexts (countries where English is the dominant language, one of the official languages, or taught as a foreign language); different levels (elementary/primary, secondary, college or university, or adult education); and different learning purposes (general English, workplace English, English for academic purposes, or English for specific purposes). Volume I, on understanding learning, provides the background information that teachers need to know and be able to use in their classroom. Volume II, on facilitating learning, covers the three main facets of teaching: planning, instructing, and assessing. Volume III, on designing curriculum, covers the contexts for, processes in, and types of ELT curricula-linguistic based, content-based, learner-centered, and learning-centered. Throughout the three volumes, the focus is on outcomes, that is, student learning. Features • Situated in current research in the field of English language teaching and other disciplines that inform it. • Sample data, including classroom vignettes. • Three kinds of activities/tasks: Reflect, Explore, and Expand.
