Tensions and arguments about controversial issues are an inherent part of going to school. Pupils can learn from these situations. Teaching in diversity offers a knowledge base regarding tense situations as opportunities for citizenship education on living in an ethnically diverse society. The book addresses which tense situations teachers and pupils of ethnically diverse classes experience and how teachers react to these situations. Teaching in diversity is relevant for educational sociologists and educational scientists who are involved with citizenship education in ethnically diverse societies. It also provides a frame of reference for teachers and teacher educators who want to reflect on the practical implications of perceiving tense situations as opportunities for citizenship education.
