HIST2B . Blumenthal 3 Months Ago

Blumenthal is not the best lecturer, but shes rly nice. The way she lectures for 2B is very confusing bc its not taught in chronological order like a typical history class, she goes over general concepts/empires & then you need to connect them yourself. The midterm/final aren't bad, and as long as you study the study guides well, its not too hard.

HIST2B . Blumenthal 3 Months Ago

Blumenthal is sweet but not great at lecturing, she is a bit hard to follow. When given the key terms for the midterm/final I didn't recongnize many of them. The essay is pretty easy, you just pick one source to examine and tests were fine. Just use flashcards for the IDs and plan an general essay outline and you will be fine.

HIST2B . Blumenthal 4 Months Ago

such a bad professor, rambles A LOT, mumbles, stutters and speaks really fast, can't understand half of what she says. I wish i never took this class. Midterms are 4 short response, 1 essay question, for second midterm it's a take home paper that's being graded tough. TA tough graders but helpful, without them i wouldn't know what what's going on

HIST2B . Blumenthal 5 Months Ago

Really bad professor, she rambles/stutters and yaps too much. Feels like she won't prepare you for the midterms, 2 days in, I already wanna drop. All she do is glaze maps and really boring lecture, don't even go. Hopefully the readings will be fine... Try to not get this class pls.

HIST117C . Blumenthal 2 Years Ago

She rambles A LOT in lectures. Also, I literally quoted something she said from lecture in an exam, and she circled it and put a question mark (and I assume marks points off), which is annoying. This is not the class to take for an easy A. 7 reading responses (2-500 words), in-person midterm w/ study guide, 5-pg paper, and an in-person final.

HIST118A . Blumenthal 2 Years Ago

I feel like a lot of these ratings on her teaching style are unfair, I thoroughly enjoyed her class and she has an obvious passion for teaching. I would recommend using her office hours as she will help you shape your essays and is clear with what she wants. I would definitely take her again given the opportunity, but a lot of writing and readings.
