Despite the superdiversity of an increasingly multicultural and multilingual world, policy and practice in education continues to deal with issues of inclusion and diversity in language education in rather tangential and peripheral ways. To address critical issues in multicultural and multilingual education, with implications for curriculum, teacher preparation and pedagogical practice, this volume brings together international perspectives on research, policy and pedagogical practice that help the global community gain new insights into ground-breaking work that addresses current questions, challenges and complexities in an education world of superdiversity.
