• "Mr. Chang has been very prepared for class and gives very helpful sheets of paper that can be used as a study guide for the test."
• "Mr. Chang is a good instructor. Did his best to explain the subject matter in class. Would always be willing to help if needed."

• "The extra help study sessions before the exams were very helpful. The assignments went well with the material we were learning."
• "I think Mr. Chang did a wonderful job. He was very challenging...."
• "I think the instructor's availability after class was excellent. He really seemed to want to help."
• "He did his best to make sure the class knew how to do the problems he provided. He always gave help and review sessions that helped even more. His tests were challenging, but it was good to make us think about the material."

• "Mr. Chang has been a part of my motivation to change my major to Mathematics. He is very helpful when asked about Math or Maple."
• "...He required extra credit on most assignments and his required format for lab assignments helped us understand and it heightened our ability. We had to actually explain our technique and this made up for most of what the grade result would be. The lab teacher helped me to see new insights on math although I'm not a big fan of the subject."
• "He explained very well what it was that I've needed to be doing and he also provided a help file and answere our questions when we were having trouble. He seemed to want us to enjoy Maple as much as he does and was very enthusiastic."
