Abstract: The topic of heterogeneity not only plays an important role in schools and teaching in German-speaking countries, it is also being researched worldwide. The special view that is taken in the presentation refers to cultural, social and performance-related diversity in the classroom. The school pedagogy makes a genuine contribution to pedagogical professionalism in dealing with heterogeneity for (future) teachers. Therefore, in the short presentation, some perspectives of school pedagogy on the topic will be presented and documented with own research.
