Book excerpt: Use this unique volume to transform the learning and teaching of language so that all students are empowered to succeed. This book offers insight into how to teach language--a core component of developing skilled readers and writers across all content areas--in ways that value the rich and diverse language assets students bring to the classroom. The authors provide guidance to help K-12 teachers move beyond current approaches to teaching language in the classroom to support equitable student outcomes in both linguistically diverse and linguistically homogeneous classrooms. The text provides a step-by-step process to uncover conceptions of language and its instruction that undercut opportunities to learn. Readers will gain new strategies for teaching the language of school tasks while integrating students' distinctive language experiences as resources for learning. School leaders will learn how to implement a schoolwide exploration into teaching language that promotes equity, all while building collaboration among administrators, teachers, and students.
