He is my favorite teacher in west. I looked forward to going to his class everyday and he has influenced me to want to become an engineer. I liked physics so much i decided to take AP and that was a
Awesome guy!!!!!!!!!!!!!! So very sweet, and is extremely smart. But, that is the downfall, because he is so smart it is hard for him to teach.but. Overall he is awesome
My favorite teacher at west. Extremely smart and its easy tp learn the information if you pay attention.
Look, he's a nice guy and all, but he favors women by far, and quite honestly, doesn't teach the material very well. You have to teach yourself a lot of stuff. Take another physics teacher if you can.
This is one of the best classes I've ever taken. Dr. D is great! Although, his physics class IS harder than the other class's. If you're up for a challenge and lots of studying, go for it!
Hands down the smartest teacher in the district good teacher
One of the best teachers in the district. Very smart. Can really learn a lot from him.
He's sweet, but I can't seem to understand anything he teaches.
Ok realy smart guy, but can't explain stuff if his life depended on it.He makes the easiest things difficult to understand with his big words. If ur in AP calc, you'll b fine since most of it is math anyways.if not,good luck!
Mr. DeCoster seems like a friendly person, but he obviously cannot teach students at a high-school level. He does not mind boring his students nor underteaching them only to create ridiculously difficult tests.
Dr. DeCoster is one of the coolest teachers at this school, and most likely the smartest. He can be really funny too.
Excellent teacher, especially for those of us who aren't good at the practical parts of physics but love the concepts. He is one of the best at West. It's all about the mustache
DeCoster is the best. It was fun in his class. Tadey
i love dr. decoster. it all started one day in the high school and i walked past and said to my self, this man could be a cologne model. ode de science.
he can get boring, I might have fallen asleep a couple of times, but he's a cool guy, and really smart.
i wish he would express himself more instead of being so monotone. But - he's very nice and helpful.
One of the only teachers i ever thought explained their subject so well for me to understand it
Sometimes I fall asleep, but an AWESOME guy, knows his stuff real well and has a great sense of humor.
Awesome teacher who knows his subject area in and out. Amazingly, I got an A in physics, thank to him.
Dr. Decoster is one of the few teachers that is a genius in his subject and loves his job to death! He is thoughtful and extremely fair. He never gives up on ya
Mr. Decoster teaches from the heart! He is fair, caring, and helpful. Thank you for being such an outstanding teacher!
You are the best teacher. We love Particle Physics and you make good cake!
Brilliant! Has a PhD in physics, worked at Stanford and Berkeley. Takes dedication to give that up to teach at Niles West
he's a VERY DEDICATED teacher who CARES. he is well deserving of praise
really nice and cool guy. great teacher too, very helpful & cares about students
He is such a nice, intelligent, brilliant, caring teacher. He's a great guy!
Awsome Teacher, But puts you To Sleep. Love his Class!
best guy ever, awesome teacher, awesome person. get him alone after school,helps
If you can speak Decosterese he is a great teacher. that is a big IF...
Some of us wonder why he still didn't receive a Nobel Prize.
puts you to sleep, but is really cool and really smart if you can stay awake
Knows more than all the science teachers combind, but can talk anyone to sleep.
A teacher who cares about his students and loves what he teachers. A genius.
hes so good at teaching, he really knows his stuff and he CARES...great teacher!
He cares about his students and loves the subject. He is a genius
I have no idea what went on in Physics but I'm sure it was interesting
The guy is a genious. He should be working at NASA or something
DeCoster is so smart....why is he teaching at Niles West?
