Bilingual Education in the 21st Century addresses languages and bilingualism at both the individual and societal levels. The book presents various program formats, variables, and policies within bilingual education and concludes with a look at practices, particularly pedagogical methods and assessment. This engaging work is an ideal textbook for future teachers and offers school leaders and policymakers a new perspective on the topic. The book provides an overview of theories and practices of bilingual education worldwide and expands traditional views on bilingualism and bilingual education by considering global and local issues of the 21st century. Assumptions surrounding language, bilingualism, and bilingual education are challenged, and a new theoretical framework is proposed, along with alternative approaches to teaching and assessment. International bilingual education policies are reviewed, with separate chapters devoted to US and EU language policies in education. The book explains why bilingual education is beneficial for all children worldwide and presents examples of how it is put into practice.
