 ## Lecture format (90 minutes)
 ### Rationale
-During lectures, new content is provided to students. The idea is to keep engagement high using interaction an by extensively activating prior knowledge. We take some time for questions and discussion during the lecture and are aware of the facts that many concepts are outright confusing to beginners. During discussion, we encourage students to answer questions of fellow students. However, we actively make sure that discussions don't divert from the subject.

 To activate prior knowledge, we start each lecture with a recap on the subject of the last lecture with quiz questions. Once that's done, we relate content of the current subject with content of prior lectures where possible.
 
-We also relate content to other programming languages, taking into account the intermediate C++ knowledge students have. This can be done by asking questions such as 'How would you solve this problem in your favourite programming language'? However, as relating to

 Apart from that, we focus on the 'why' of each concept, as it helps students to better internalize the contents, and it allows them to creatively apply the gained knowledge in doing exercises and in the final project.
