'The strength of the book is that examples from classroom research are used to demonstrate how meta-language about grammar and meaning can be included, rather than added separately, in a content lesson to support language development... Chapters 3 and 4 contain many valuable subject-based examples, used with both young and adolescent learners... This volume is a welcome addition to work taking this view on how language development is involved in content learning. ...this book is valuable both to TESOL students and practitioners already familiar with a functional approach and to those whose thinking and practice is moving in that direction.'
