Teaching evaluations (EPS80 - 2022, UC Berkeley):
"I was genuinely surprised that I've enjoyed a class outside of my major so much."
"The instructor's approach to assessments/ exams was refreshingly learning–focussed rather than memory–focussed. "
"The strengths of this course are definitely the course layout and organization of all the topics and subjects we covered throughout the semester. Everything we learned flowed together pretty well, and there was a nice transition from one topic to the next. Also, I really enjoyed the multiple mediums we had for the homework in class. The homework was fun and allowed me to feel confident in my work and get out of my comfort zone. In addition, I like how her class instructions encourage students to participate by asking us questions and answering them even if we have no clue. This really allows us to grow and be comfortable of not knowing information."
"I really like the way everything is explained so thoroughly and understood the first time around. Makes it so that if you just attend the lectures you should be good. I also like how the focus of the course is not to pass a test, but to learn, and the test just helps facilitate that. That's what I believe school should always be, and it's truly disheartening that this is an exception and not the rule"
"I love Professor Wieser's lectures. It's informative, engaging, and fun to listen to. She often makes jokes to engage the students and I appreciate how effectively she makes really dense information into understandable concepts."
"The professor is clearly very passionate about whatever she talks about. She was always prepared to answer any questions we had or redirected us to the appropriate sources when she wasn't confident in her own answers."
