This volume contains interdisciplinary essays on bilingual education in various countries of the world. Some contributions deal with policy and curricular issues with regard to minority and majority language, some consider the enrichment aspect of bilingual education. Others focus on language maintenance and revitalization, still others look at ways in which bilingual education could stabilize the functions of the societal languages. All contributions support bilingualism in society and consider how bilingual education could promote that goal. A special section is devoted to US policies and politics.
