This thorough fourth edition of a foundational work will equip the next generation of teachers to instruct multilingual pupils who are classed as English language learners (ELLs). This is the authoritative textbook for preparing K–12 educators and administrators to achieve state competency requirements and support the success of their multilingual students. It was written by one of the top authors and researchers on English Language Learners (ELL) and bilingual education today.

This foundations text, which is intended for undergraduate and graduate foundations courses, has been completely updated to include the most recent findings, theories, regulations, important subjects, and best practices. Future teachers will learn how to differentiate instruction in core subject areas, effectively use new technologies, plan rigorous standards-aligned language and literacy instruction, differentiate instruction in core subject areas, differentiate instruction in ELL-classified students, and use students’ home languages as learning resources.
