Koen is the best professor I've ever had! I loved his class, the 1 lecture 1 lab a week setup is great. His course challenged me but it was super fun. He's such an interesting guy and his lab assignments deal with real-world problems and solutions across social and environmental sectors. Great class and he teaches code really well for beginnersENVR5563 2024-05-14 23:07:07 +0000 UTC
I love the way he teaches. I don't think I've been to a class that was as interactive as his was. The PollEv is super useful and ALSO he recorded all his classes!ENVR1500 2024-03-19 15:45:49 +0000 UTC
Koen is what Northeastern needs. He cares about his students and views his class as a way to teach students what he learned working in the field, and more as sharing information, not lecturing. Class is set up as 1 Lecture and 1 lab a week, 8HW, and a project, although this is a grad course, work was never unmanageable. Great Professor!ENVR5563 2024-05-05 17:58:51 +0000 UTC
He is a great professor that is very knowledgeable on the subject. There are very few assignments for the class which is not my favorite thing. The lectures can get boring but if you take notes you'll do well. There is a zoom link but he prefers you not to use it unless necessary and there are poll everywhere questions.ENVR1500 2024-03-18 17:31:16 +0000 UTC
Super nice and funny. The course content is really interesting, but can be challenging especially when we learn more about probabilities, statistics, and coding in R. Always provides the slides for the lecture ahead of time, and always has a Zoom link for the lectures in case you can't be in class.ENVR1500 2023-12-06 22:30:00 +0000 UTC
He's a very sweet guy who's very understanding. There are only two big assignments and a few homework that were easy enough. The lectures can drag on sometimes but he gives breaks and he's pretty funny.ENVR1500 2023-12-02 03:20:15 +0000 UTC
