This guide to teaching English language learners (ELLs) is written as a text for pre- and in-service ESL and bilingual teachers, as well as mainstream teachers, staff developers, school administrators, and others who work with ELLs. The authors, teachers of ESL and bilingual education at The University of Texas-Brownsville, identify and discuss the linguistic, social, and psychological factors that affect students who are learning academic content in their second, third, or fourth language. They also review recent research and theory on first- and second-language learning and describe best classroom practices. Numerous classroom examples and case vignettes are based on the authors' experiences. This third edition includes a new chapter on bilingual education and new material on assessment and teaching academic language. Annotation ©2011 Book News, Inc., Portland, OR (booknews.com)
