Comment:

Worst teacher I have ever had at UNCW. Dr. Chang does not post any solutions to homework or tests and will not explain what you did wrong leaving you no way of learning the correct way to complete problems. He gets upset if no one comes to office hours but once you go he will treat you as an inconvenience. Would not recommend to my worst enemy.

Comment:

Let me start by saying prof. chang had a thicker accent than my native Chinese teacher. She spoke better english than this man. Add that and super fast, lazily explained lessons and ur screwed. He gives half the test online and I still failed. He usually teaches higher level courses so he didn't seem to give a crap the whole semester.

Comment:

Really cares about how his students do & wants everyone to understand the material- he'll go over it as many times as needed. TONS of online homework (like 3-10 questions per unit, 2-3 times/week) and 3-4 tests inc. final. Homework was super easy and had multiple chances; tests were in class & online and were hard for most of us but everyone passed

Hard to understand. Lots of homework (its easy though). Lectures are heavy and boring. Tests are hard and half online. Thought this class would be an easy math choice for a non-math major, I was wrong. Do not take

Comment:

495 is a tough class. Dr. Chang doesn't really teach you the LATEX coding, but he will help you learn it if you get stuck, so don't worry about the coding part. He has very high expectations and he will make you feel dumb, but it isn't intentional, he just wants you to put in a lot of work and thinking. Don't fall behind on your paper.

Great teacher. Grades homework tough but not that bad on tests. Very willing to help. People who say he makes you feel stupid just need to understand he is from a different country and sometimes comes across a certain way. Extremely nice and easy to understand. The class is straight forward but the class is proofs.

Comment:

Dr. Chang is an amazing professor. The class is basically all proofs so be prepared. He teaches through a powerpoint and writing notes in it. There is graded homework assigned every class, but it is generally only 2 or 3 problems and not very difficult. Tests are based off homework so its helpful. Only complaint is he grades hw though. Take him!

Love Changy. He's such a sweet man. Very hard to understand sometimes though because his English isn't perfect. But he gives you 5 chances to get a 100 on every homework assignment. There are 4 tests including the final and half of the tests are online and open book and open note. Easy to get good grades on the tests. Highly recommend him!

He has just the right amount of homework, enough to help learn the topic but not a lot. Powerpoints are clear if you pay attention. He has a small accent but it isn't too hard to follow. You need to study for the class but it isn't a hard class at all.

Professor Chang is an excellent teacher of mathematics. He is organized, offers a well-designed class, is always available for help when needed, and has high expectations for his students. He also emphasizes listening to his lecture, understand what's being taught, rather than wasting time copying his examples; he posts all lecture notes online.

He is a very confusing teacher. He would give examples and not allow enough time to write them down. When I tried to go over his examples later, I was unable to read his handwriting. I would not recommend.

Very organized. Mandatory attendance. Usually has a quiz for each section of notes, 5 chances to take each quiz and the highest grade is kept. He explains things very clearly and is funny sometimes. You will have to study, if you want a good grade, but the class isn't really that hard. Don't fall behind and you will be fine.

Excellent professor. Has a well designed class plan with online accessible lecture notes which are helpful if you forgot something. Homework is almost always daily but well structured in a way that really helps you memorize concepts. He's also very helpful out of class if you need it. Only complaint is that his handwriting can be messy at times.

Comment:

Once you fall behind, you're doomed for the whole semester. Very hard to understand, will do a problem on the board and at the end will say "This is what not to do" after everyone just wrote it down. The only reason I got a B is because I befriended a math major for the online portions of the test.

Professor Chang is a very nice guy. His axiomatic systems class can get to be difficult to wrap your head around. Many people in my class struggled to understand him, but he still did a very good job teaching what we needed to learn.

Most of class is spent watching him go over examples that nobody has time to copy down. He is difficult to understand. Make sure to go to the Math Lab as often as you need because you're screwed if you fall behind. On the plus side, he is nice and half of each test are online.

Comment:

Dr. Chang is pretty hilarious but intense. He wants you to succeed, but he wants you to work for it (slacking off is an easy way to make him mad). Be prepared, ask questions, do the homework as soon as possible, and there won't be problems.

Comment:

This teacher has zero interest in helping his students. If he does not like you, it will be reflected in your homework scores. During finals week, he WILL NOT answer your emails regarding any questions you have. The homework is 25% of your grade, and it is on material you have not yet learned. AVOID AVOID AVOID!
