Valentine is a very laid back professor. I felt his lectures were very clear and reflected almost exactly what would be on the tests. Plus, he provided a study guide with topics before each exam. Seems like a genuine guy who really loves what he does. Don't buy the book, didn't open it once. Section activities are very easy as well.

Awful at explaining simple concepts. I learned almost everything from my textbook (get an early edition, it's the exact same and costs $4). Made fun of students during lectures. Took a whole lecture showing us unrelated videos of his research. Unclear about what would be on tests. Nice thing is that he grades on a generous curve. Do not recommend!!

I loved this class and I loved Dave. He was super funny and really passionate about his field. He talks a lot about his research (which I found super interesting) and related oceanography to every day life. Creative tests (i.e. not just multiple choice) that were pretty easy if you pay attention. Loved him, would definitely take again. Easy GE.

Everything is based on the lectures, however I was one of the those students who actually bought the textbook and found it really useful for the labs, and study guides he provided us for the exams. His teaching is boring but the material is interesting. Can be an easy A (due to curve), although his exams were a little more tedious than expected.

Class is boring and fell asleep couple of times. Tests are super specific on dates and irrelevant events. Has a huge curve though.

Lectures are useful to attend, because much of what he tests on is from the lectures. Sometimes, he tests on things that seem more trivial. Sections are simple. Attendance at lectures is non-mandatory, but you must at least turn in the weekly section assignment to your TA. 15% sections, 2 midterms each worth 20%, and a cumulative final worth 45%.
