From the Preface:

This book is intended for graduate courses in Applied Linguistics and Second Language Acquisition or for advanced levels of undergraduate teacher education programs.

I hope also that practicing teachers will read the book as a source of professional development, as well as other educators, curriculum designers, and administrators working in a variety of second language instructional settings, whether content-based or not.

While the book aims to enable educators in immersion and content-based classrooms to consider ways of integrating more focus on language, I hope as well that it will inspire educators in traditional language classrooms to consider integrating more content-based instruction as a means of enriching classroom discourse.
