Based on Improving Schooling for Language-Minority Children, a comprehensive study published in 1997, this book summarizes for teachers and education policymakers what has been learned over the past three decades about educating such students. It discusses a broad range of educational issues: how students learn a second language; how reading and writing skills develop in the first and second languages; how information on specific subjects (for example, biology) is stored and learned and the implications for second-language learners; how social and motivational factors affect learning for English-language learners; how the English proficiency and subject matter knowledge of English-language learners is assessed; and what is known about the attributes of effective schools and classrooms that serve English-language learners.
