Teaching English Language Learners: Content and Language in Middle and Secondary Mainstream Classrooms is a user-friendly guide for planning, implementing, and assessing high-level, content-area instruction for English Language Learners. Starting with an overview of second language acquisition and the cultural variables that impact teaching and learning, this text goes on to detail planning strategies, units and lessons in the subject areas where it is most difficult to shelter content and scaffold language skills: middle and secondary Math, English Language Arts, History, and Science. Teaching English Language Learners will leave preservice teachers with a foundational understanding of how to purposefully structure, build, and present effective lessons for English Language Learners in these mainstream, content-area courses.
