 Welcome to a hands-on unit where we will discuss the principles underlying the digitization of content, but at the same time deal with the problems and obstacles. As usual, you should start with the main content activities where we first look at the goals of digitization, then at possible sources for easy content generation, and finally at the prerequisites and obstacles. Please use the question set in the how to proceed section as guidance if you don't know where to start. This unit's mastery test is an input task about digital content production, but it should not be problematic after having mastered the main content. Well, and in our suggestions for in-class activities, we want you to do some group work and search for videos, platforms and other digital elements. Try on your own first, the model suggestions will come up later. So this unit involves a number of new hopefully interesting aspects and we made it as accessible as possible for you. I hope you agree. And by the way, don't forget to tick off the activities you have successfully mastered.
