 Hello and welcome. This unit discusses the main changes that occur when we rethink teaching and learning. It shows that the teacher role, as well as the ways students acquire factual knowledge, changes dramatically. As a starting point, you can use our question set from the How to Proceed section as default guidance, you know, when you can answer these questions you have mastered this unit. In the main sections we look at the principles of digital integration with a focus on what we call comb models and the new role of the human coach. This includes the discussion of new classroom architectures. This unit's mastery test is an input task about these new teaching and learning scenarios. It should be easy after having studied the main content. The suggestions for in-class activities, by contrast, want you to search on the web something you always do, don't you? Try on your own first. The model solutions will be given later. And a reminder, don't forget to tick off an activity once you have successfully completed it.
