Suggestions for In-Class Activities

Each unit ends with some "Suggestions for In-Class Activities", i.e. with a set of questions, problems, quotations presented as text, image or video. These suggestions can but don't have to be used by the class instructors. However, answering the questions or solving the problems presented here have shown to be useful over the years. And all problems/questions in the "Suggestions for In-Class Activities" are coupled with model/practical solutions visible for all those who have the teacher or teaching assistant role on this platform.
