Teaching English Language Learners: Content and Language in Middle and Secondary Mainstream Classrooms provides a reader-friendly guide to implementing and assessing high-level, content-area instruction for English Language Learners. Beginning with an overview of second language acquisition and the cultural variables that impact teaching and learning, authors Michaela Colombo and Dana Furbush go on to detail planning strategies, units and lessons. Practical in nature, this text focuses on the areas where it is often most difficult to make content comprehensible and build academic language skills: middle and secondary math, English language arts, history, and science. --from publisher description
