Professor Gwinn was highly inaccessible outside class, never answered emails, short office hours. Her teaching style is based more on the basics rather than proofs or details. She was fine, but I wished she communicated more with her students
Her lectures make you more confused that you would've been had you not gone to class, but sadly the iClicker points are important. She's been really nice about grading the curve based off each person though. Go to class ready to do the online homework (due twice a week) during lectures to save time.
In comparison to Freedman, Gwinn is a saint. A much better alternative. She actually teaches in class, and there is one big homework assignment due Fridays, which suck, but it is better than having homework everyday. The grading scale curve is very generous, a 55% is a C-, a 85% is an A-. Her tests are hard, but she drops the lower midterm.
Her lectures are organized so it may be hard to tell that it's largely nonsense. With a bizarre subject like quantum mechanics, she should have been clear about what equations or concepts you can always fall back on and experimental information would have been helpful as well to understand the phenomena. She also conveniently didn't give out evals.
I'm not sure why there are so much negative feedback here. The lectures are clear and well-organized, the tests are reasonable, and the homework is very useful in preparing for the test. Though the class is not easy, the resources to succeed are readily available. Overall, Prof. Gwinn is an above average lecturer.
Gwinn must have improved from past years because I don't think she was nearly as bad as some of these reviews say she was. In class she teaches you the basic formulas and concepts and it is up to you to figure out the tough homework problems. The quizzes in section were very hard but she ended up dropping most of them. Tough tests, but big curve.
