The European Commission-funded REDCo project considered how religions might contribute to dialogue or conflict in Europe. Researchers in education from eight countries (England, Estonia, France, Germany, the Netherlands, the Russian Federation, Norway and Spain) co-operated in studying how young Europeans of different religious and cultural backgrounds could engage in dialogue in the school. Empirical studies, with 14-16-year old students, included their own perspectives on teaching and learning. There were some different national patterns, but most students wished for peaceful coexistence across differences. Most considered that peaceful coexistence depends on knowledge about each other's religions and worldviews, sharing common interests and doing things together. Students who learn about religious diversity in school are more willing to discuss religions and beliefs with students of other backgrounds than those who do not. Students want learning to take place in a safe classroom environment with agreed procedures for expression and discussion.This book reports examples of the project's qualitative and quantitative studies and includes essays reflecting on the project's methods and theory.This book was published as a special issue of the British Journal of Religious Education.
