Diversity - social, cultural, linguistic and ethnic - poses a challenge to all educational systems. Some authorities, schools and teachers look upon it as a problem, an obstacle to the achievement of national educational goals, while for others it offers new opportunities. Successive PISA reports have laid bare the relative lack of success in addressing the needs of diverse school populations and helping children develop the competences they need to succeed in society. The book is divided into three parts that deal in turn with policy and its implications, pedagogical practice, and responses to the challenge of diversity that go beyond the language of schooling. This volume features the latest research from eight different countries, and will appeal to anyone involved in the educational integration of immigrant children and adolescents.
