Christina is a goddess. Having taken Frontiers of Science first semester and having hardly had the best instructor, I was more than a little apprehensive about the workload of UWriting. But Christina disarmed my assumptions from the very first class, simultaneously an imposing figure with a you're-going-to-do-your-bloody-work-and-we're-going-to-fix-your-bloody-writing-aren't-we attitude and a colloquial, approachable, friendly individual.
Her reading selections are always very thought-provoking, and she participates in discussion as if she were a student herself, while somehow, ingeniously keeping track of what she wants to cover. She structures her classes around what she's noticed her students need help with. At the same time she's absolutely concerned with students' well-being and was able to empathize with us, understanding delays and granting leniency when necessary -- she's also able to enliven class discussions between college students at 8:40 in the morning, a herculean feat in its own right.
Office hours (at least one is mandatory for Progression 1) are insanely helpful. My first writing conference was probably the most productive 15 minutes of my life, and the rest didn't disappoint after that. Christina's written feedback is always thorough but clear and concise -- and if you follow her suggestions between exercises, formal draft, and final draft, your writing (and your grade) will improve dramatically. She pays a lot of attention to your work, and her end comments are incredibly useful.
Christina is one of those grad students who want to become a professor because they want to teach, and she's really quite good at it. I highly recommend her if she's still teaching UWriting next year.
