Designed for pre-service and novice teachers in ELT, What English Teachers Need to Know Volumes I, II, and III are companion textbooks organized around the key question: What do teachers need to know and be able to do in order to help their students to learn English? In the Second Edition of Volume II, Murray and Christison return to this essential question and cover the three main facets of teaching: planning, instructing, and assessing L2 English instruction. Addressing new skills and strategies that ESL and EFL teachers require to meet the needs of their shifting student populations who are impacted by changing demographics, different learning contexts, and digital environments, this book offers a strong emphasis on practical applications for classroom teaching that is grounded in current research. This updated and expanded Second Edition features: A new section on teacher learning, including a chapter on exploring digital technologies in ELT. New and updated classroom examples throughout Discussions of how teachers can prepare for contemporary challenges, such as population mobility and globalization The comprehensive texts work for teachers across different contexts-where English is the dominant language, an official language, or a foreign language; for different levels-elementary/primary, secondary, university, or adult education; and for different learning purposes-general English, workplace English, English for academic purposes, or English for specific purposes.
