My friend and I wrote an anonymous complaint to the Physics Department Chair about our Introductory Physics II Professor. In all honesty, the professor is a very nice man who's passionate about physics, but teaching is definitely not something he's good at. This is what we put in the letter:
1) The professor constantly goes off curriculum by teaching the class about advanced physics topics that involve biology (e.g. the process of random walks, resistive forces and diffusion, the physics behind gel electrophoresis). He's essentially teaching us his research and he believes that we will appreciate his lectures. Instead, he confuses the entire class and doesn't understand why people didn't do well on the first exam, which was all about fluids and biophysics.
2) A *lot* of people cheat in the class. When I mean cheat, these people do it so openly and the professor doesn't know what to do about it. To put this in perspective, this professor cannot control a class of 85 students who talk so loudly during a quiz. Yesterday, there was a quiz in the class and there were so many people talking that the professor actually said, "Guys, I'm okay with you guys bouncing ideas off of each other, but please try to keep silent".
So my question is that since my friend and I put the complaint in the Department Chair's mailbox, what would probably happen next, considering that we made this complaint anonymously?
