This book lays out a radical new all-in approach to teaching in linguistically diverse classrooms: that everyone, including those who already speak the school language, is included in multilingual pedagogy. The author argues that school language speakers are the missing piece in multilingual teaching and provides a new resource, Linguistically Appropriate Practice Plus (LAP+) to help teachers engage these learners in meaningful language tasks and support their language skills and interests. With all learners on board, multilingual teaching becomes pedagogy that is fully inclusive and linguistically fair.
