Baker's "Foundations of Bilingual Education and Bilingualism" is the MUST-HAVE definitive guide to bilingualism for anyone who is interested in the topic. The guide is a comprehensive guide to second language acquisition, bilingualism and cognition, language policy, bilingual education research, and anything else you ever wanted to know about bilingual education. This book would also be helpful to anyone who is interested in the study of second language acquisition, as well as the education of English learners. This book is the best book I ever read about bilingual education.
