Book excerpt: Referred to by readers as "the greatest language book I have every read," and touted as the best overview of basic principles and strategies for English language teaching, this widely used guide is a one-stop introduction to teaching English to speakers of other languages. A highly-praised, passionately-written overview of basic principles, practices, and methods for educating English learners, this much-used guide covers such topics as multi-level methods for differentiated instruction, Common Core standards, teaching of content vocabulary, and computer-mediated instruction. It's designed to maximize teachers' effectiveness in three major areas-1) expanding English learners' access to the core curriculum, 2) instructing all students with a rich and demanding curriculum, and 3) making crosscultural connections through teaching practices and curricular content-and to work at many levels simultaneously. A breakthrough in language teaching and learning, this thought-provoking text includes coverage of second-language-acquisition issues and techniques, as well as attention to such controversial topics as the influence of culture on schooling, the cultural practices of schooling, and the sociopolitical context of education.
