In 1976, at a conference held by the Baden-Württemberg state agency for civic education in Beutelsbach in Swabia, scholars of civic education found three points they could agree on. They are still an important reference for civic education. Teachers may not overwhelm students into holding desired opinions. Students must be enabled to analyze a political situation and their own interests. And the second rule reads: Was in Wissenschaft und Politik kontrovers ist, muss auch im Unterricht kontrovers erscheinen. (What is controversial in scholarship and politics must also appear controversial in the classroom.)
