Allows students to actually show what they have learned, without artificial restrictions or very limited time of an exam environment.
The more you make it critical and open, the more you learn about genuinely [...] what the student learned.
On an exam of at most 3 hours [...] you don't have the space to give them a larger assignment in which you can really sense what they are capable of. [...] I can test that they get the hang of the technique, but not that they can apply it in a larger project, so that's why I think the project is very important.
