I had heard a lot of negative things about matthias' personality, but he is quite nice in person(not on piazza). He's lectures are very engaging. This course had a lot less homework compared to his other class(cs4500, which I didn't take), and is graded very leniently(85% is an A).CS4400 2025-12-04 01:29:43 +0000 UTC
Best prof ever! It's a shame so little students understand the value from his class...CS4500 2025-02-11 15:32:17 +0000 UTC
Changed Northeastern from a Java school to a Scheme school. First to crack the full abstraction problem - a long standing open problem. Robust teacher - has ACM's highest teaching honor. yeah, quite distinguished and know's what he's doing. It would be a pity if you had a chance to take a class with him and decided not to.CS2500 2018-08-20 20:46:32 +0000 UTC
Extremely rude and partial in giving marks....CSG107 2008-12-09 09:39:18 +0000 UTC
I hated his guts while in his class, but in retrospect he's almost certainly the best teacher I've ever had. As somebody said above, this guy is absolutely brilliant. He will kick your butt, but it's all for your own good in the end. He seems to really care about teaching, and it shows.CSU660 2007-11-13 22:48:52 +0000 UTC
Avoid software dev with him unless you want to do 30+ hours of homework a week. I learned a lot from the class, but the workload simply wasn't worth it. He makes assignments intentionally unclear just to piss you off. He claims it simulates the real world. That may be true, but that's also what co-op is for. Avoid him if at all possible.CSU670 2007-05-09 04:00:15 +0000 UTC
Class consumed my life but it was worth it. Don't let my ratings fool you, the teacher was intentionally unclear and unhelpful to simulate real life. However, the course itself is one of the best I've taken at Northeastern and will help you improve a lot.CSU690 2007-04-25 15:12:03 +0000 UTC
I love how he comes to class empty handed. He definitely knows what he's talking about. The man's brilliant.CSU211 2007-01-11 19:55:43 +0000 UTC
This teacher is awsome, my class is @ 9:15am, but he makes it so intresting. Its only hard if you hate computers, or already know too much and refuse to let go and start from scrathCOMP111 2006-09-25 17:38:28 +0000 UTC
excellent. hes intimidating, but its good. he forces you to learn or suffer and drop CS. hes good for a first cs class bc he makesc (not literally) the people that arnt up to it to drop from the cs major.211FUNDOFCS1 2006-04-03 13:16:59 +0000 UTC
He was definitely the hardest and one of the most brilliant professors I have ever had. I have also learned more in his class than I had in most others. The projects and code-walks were consuming pretty much all of my time (days, nights, weekends, holidays), but I think that I landed my first job thanks to that class.SOFTWAREDESIGN 2005-09-27 09:48:04 +0000 UTC
Very loud and energetic, I thought he was hilarious. Most hw assignments were pretty easy, just alot of **** lab assistants. His midterm and final varied in difficulty, but generally you're gonna need to put the time in w/the books. work hard and you'll be fine. Very nice guy though.FUNDAMENTALS1 2005-04-07 11:55:03 +0000 UTC
he is my god..if i could have him as a private tutor i bet i could quit college and know much more than others :) the best teacher ever!CS211 2004-12-08 18:37:13 +0000 UTC
Felleisen was one of the best professors I had during my five years at NEU. He pushed the students willing to learn towards gaining an incredible amount of knowledge, but was not always there for the ones that needed help. Highly recommended professor! A++++! Would take classes again! He = God;COM1205 2004-12-05 20:41:48 +0000 UTC
