Fall 2019 - As a person, professor Chang is the nicest professor I've had yet at UCLA. I wish I liked his teaching style as much as I like him as a person. He reads exclusively of off powerpoint slides during his lectures and rarely does examples in class. There is no required homework to turn in but exercise problems are assigned each week. The exam problems are easier than the homework problems. There is also a 5-minute presentation in which you describe a journal paper related to mechanical vibrations. There is also an extra credit opportunity to write an Android/IOS app worth 15% of your grade.
