According to the writer, bringing hours to 40 minutes can only benefit students and will allow teachers to teach on multiple class groups.
This is precisely the novelty according to Affinati: teaching by levels. No longer all who follow the same lessons, but differentiations that will lead to leveling upwards.
A reflection also on outdoor lessons or in museums: the teacher becomes a guide, the evaluation becomes shared because the teacher shows the whole work done together.
Obviously, Affinati speaks of resources: of those that, however, there are never enough.
