Prof Koehler may not have the experience required to be the most effective lecturer, but she is willing to commit time and effort to help students. You do learn a lot from the course, and her exams are quite easy and straighforward.

Let's face it. She brings in Powerpoint slides. She does gives them to you, which is good. She is a nice person, but says "don't send me e-mails". But, most of the time, she really does'nt know what she's saying. I came out of the class not knowing what she was talking about. That is to say, she can't teach. But, as is usually the case, if they can't teach, the tests are'nt as bad. That is to say, they are striaghtforward. You know the stuff (have it memorized) you will do great in this class. YOU MUST READ THE BOOK AND TAKE NOTES YOURSELF. I used the lecture to leave myself marks on what to read, because sometimes the stuff you think would'nt show up on the test, shows up! If you do that, memorize them, you will go great in the class. Plus she gives problem sets, and pulls one problem from each and puts them on there. Don't just copy them. Try to do them, so you can remember the answer when she puts one on the test. If you ask me, I don't care about the teaching abilities of the teacher. I care about the tests. So based on her tests, I will highly recommend her.
