He is a new professor here at UWL. Although it was rocky at the beginning of the semester, he has shown a true, honest effort to change his teaching styles for the students. He wants the student's feedback so he knows what's working/not working. Ultimately, he has shown passion for physics and more importantly, for teaching. He's a good guy.

This is the easiest class ever. The tests are super easy (problems directly from homework which he posts solutions to). People are complaining that he isn't helpful or clear, well they're wrong and they're right. He actually is really helpful if you ask him, and he isn't clear at all.

Dr. Barnes was not a helpful professor. He seemed annoyed when asked questions and was very unclear in his lectures. He did not make the grading scale clear in the beginning of the course.

It's a shame to see this professor bring down the physics department like he does. Being a physics major, I can say he's by far the worst prof in the department.

His class is easier than a high school physics class. Most of the people in the class are some sort of pre-professional majors and yet they think the material is hard? There could be no professor/lecture at all and people should be able to figure out the elementary material this class covers. The only thing he is bad at is being a lab instructor.

Physics is confusing enough without him making it even more confusing and introducing 202309729 topics, few of which are well explained.

If anything is unclear just go talk to him, he'll help you as much as you're willing try. I think he may not seem clear because 103 + 104 are generic as hell and not clear in themselves.

Just do assigned textbook problems and take every extra credit opportunity, and you will get an A. Barnes is awesome (and I personally hate math and physics, but he made me like his class). Do not understand people who complain about him. His exams are just textbook problems; no tricky questions. Partial points if you show some knowledge.

Dr. Barnes is an extremely nice guy but you will have to work for a good grade in his class. Homework is optional, but extremely important because 25% of the grade is homework quizzes and the tests are all homework problems as well. Nothing is surprising, just read before class and do the homework problems, and that is all there is to it.

Barnes is a great professor. He made very difficult material understandable to someone who has never taken physics before. He is always available if you need extra help, and he really cares that you understand the information. So don't be afraid to go to his office hours if you're struggling! I would 100% recommend.

As someone who had never taken a physics class before, this class scared me. It got even worse once we started the actual material. He gives no unit tests so you only have a midterm and a final (which there is no review for). An extremely hard class and concepts were way over my head. Sometimes moves through material too fast. Hard to pass.

Dr. Barnes is a great professor, but you only have two exams. He explains things very well, but if you didn't take physics in high school it may be tough. He gives a lot of partial credit on exams. You have daily reading quizzes which are pretty easy and also homework every week. Midterm and final are all homework questions.

Dr. Barnes is great. He's really good at answering any questions you have and making you understand the material. There are only two exams for lab but all the questions are the sample exam questions at the end of each lab. The one thing is, even if you do the sample questions there is no answer key so you don't know if you're doing them right.

Taking Barnes for physics 103 was probably the biggest mistake I've made so far as a student at UWL. The midterm and finals have content in them that are never mentioned in the book or during lecture. His lectures are the most incoherent explanations of course material. Prepare to teach yourself from the book rather than lecture. Avoid!
