In schools across the EU, teachers are increasingly facing challenges of integrating students from different cultural backgrounds. Discussions and disagreements linked to political events at home and overseas occasionally meld with broader patriarchal traditions in the classroom. They wonder: How can I engage my students in a discussion about sensitive topics they care about, such as the war in Syria or the conflict between Israel and Palestine, without it escalating? How do I talk to a student who says they are not European or Belgian or German but Muslim only? How can I differentiate between a student simply challenging authority and someone flirting or even engaging with an extremist ideology? In order to help teachers find answers to these questions, the European Foundation for Democracy and the Counter Extremism Project (CEP) have developed a Practitioner’s Guide on Preventing Radicalisation in Schools for use in Germany. It tackles key challenges educators face daily in German school life and was created via a methodological bottom-up approach by teachers for teachers.
