In this indispensable work, prominent authorities review the latest research on all aspects of ELL instruction (K–12) and identify what works for today's students and schools. Provided are best-practice guidelines for targeting reading, writing, oral language, vocabulary, content-domain literacies, and other core skill areas; assessing culturally and linguistically diverse students; and building strong school–home–community partnerships. Chapters include clear-cut recommendations for teaching adolescent ELLs and those with learning disabilities. The comprehensive scope, explicit linkages from research to practice, and guidance for becoming a culturally informed, reflective practitioner make the book an ideal course text.
