For the most part, Julia is a reasonable and fairly chill instructor. I liked how she established from the outset that the class won't be about memorizing a bunch of crap (i.e. dates, technical jargon) but learning how to look at and analyze art. Each class was structured on in-depth discussions about whatever artist/movement/artwork was scheduled for that day (as would be expected in every other art hum class--no surprise here), and so you would have needed to have done the reading or known something about the art in order to contribute/participate in a meaningful way. Given the fact that the focus of art hum (as are the other core courses) is entirely western/euro-centric, I appreciated how she made an effort to include a token of modern and contemporary artists, some of whom aren't "western," though I was almost always confused about how these artists furthered my understanding of the artists featured on the art hum curriculum.
And at certain points of the course I felt as though it would have actually been helpful and more engaging if she had focused on some of the technical terms thrown around in art history. For example, in her mini-lecture on the Parthenon, she kind of glossed over the Ionic/Doric/Corinthian orders (I think she spent like one slide merely mentioning the first two), though I would think these are relatively important architecture terms that need defining. If I recall correctly, she also mentioned chiaroscuro (contrasting light-dark to create the illusion of form) only once in passing; spending even just one or two minutes more on this term would have later helped me understand why Picasso's use of color was so groundbreaking in the history of western art--I had to figure this out on my own while reading Kahnweiler.
She was also somewhat biased toward Renaissance and, later on in the course, Spanish baroque painters, namely, Velazquez (btw she LOVES Las Meninas), not that I had a problem with that--I was looking forward to the Renaissance anyway--but she would sometimes use this as an excuse to avoid answering some of our more specific questions. I understand that one can't know everything about everything, but she could at least have told us that she'd get back to us on questions she couldn't answer immediately.
A note about testing. I don't know how the other art hum instructors structured their exams, but she gave us 30-ish min to complete the essay portion for both the midterm and final. 30 min to talk about three (and for the final, four) artworks! This ain't the SAT's!!! Her tests aren't impossible, and she's a fair grader--they just might be harder for those who do not have any background on art history (like me).
tl;dr Enjoyable class on the whole, though I wish she had gone over some of the more important art terms and given us more time on the exams. If you don't have some basic knowledge of the major artworks and architecture of western civ, take it with another instructor.
