For example, Germans occupied Poland, then Ukraine as a part of USSR. And this occupation went on for several years. Did universities keep on working? Schools? How did the curriculum change? I understand that there was no need to change maths. But what about history? Economics? Literature?
Were new textbooks written? Or were those lessons and faculties just abolished? Maybe someone knows concrete examples of how Germans dealt with those issues?
Was it very different in Ukraine and France for example? Maybe Germans thought that Slavs didn't need schools and colleges at all?
