While the complementary schools bilingual children attend after school or at weekends significantly enhance educational achievement, most mainstream teachers are still unaware of their pupils' other worlds. This results in the children's bilingual identities remaining hidden or marginalized, and thus underutilized. Based on two innovative action research projects in east London, this inspiring book demonstrates what can be done to change matters and describes how mainstream and complementary teachers can work together as equal partners to: build rapport with pupils; help children become independent learners; create a learning community within the classroom; maximize children's bilingual resources; and develop a holistic approach to learning.Interconnecting Worlds tells an important story to teachers, teacher educators, policymakers and all who are studying and researching bilingual learning internationally. Each chapter includes ideas for new ways forward in school policy and classroom practice.
