 This introductory unit provides an overview of classical teaching and learning scenarios and discusses the options to make them fit for the new millennium. These are referred to as digital enhancement and digital integration. Make sure you understand the differences between these two methods of digitalization. We will first deal with the lecture, the standard teaching format in high-level education and will define its main properties, its benefits and disadvantages and will discuss the effects of digital enrichment or enhancement and of digital integration. If you are not sure what to do first, start with the how to proceed section where you find useful hints and most importantly the question set with the typoling as default guidance. If you can answer these questions, you can be sure to have mastered this unit. The mastery test, which we recommend to tackle at the end, presents some basic questions about teaching and learning using a set of different question types which are randomly chosen. Finally, like all units, we have a sheet with suggestions for in-class activities or further research. Try on your own first, the model solutions will be given later. Surely a lot of material, but we are sure at the same time enjoyable and profitable. So, good luck! And by the way, don't forget to tick off an activity once you have successfully completed it.
