He has a very interesting lecture style, it sounds like he's preaching or something. This course is very interesting though and he'll give great lectures on them, but you do have to listen through them and take good notes. He'll give warnings to when the pop quizzes are going to be. Also, you will have to keep up with the readings.

Professor Walker was one of my favorite UCSB professors. His teaching methods are a bit unconventional but so long as you go to lecture and section, it will all connect and is super fascinating. He chooses amazing things to lecture about and really cares about the students and their feedback.

I really enjoyed this class, and although his teaching methods may seem a bit unconventional, if you go to lectures, it's easy to follow along. He's clearly very passionate about what he teaches, and his lectures were super interesting. Sections allowed us to dive deeper into concepts from class and were super helpful. Would highly recommend.

Really great class. Even if you're not super interested in the subject, David Walker's lectures were just amazing. Fairly difficult and requires a lot of reading and quite a bit of writing.

One of my fav classes I have taken. Prof Walker does a great job of brining humor into lectures and they are actually really interesting. He doesn't post slides or gave much info on them, instead he uses a script for lectures so if you don't go you will prob fail. 2 pop quizzes in lecture, and midterm and final are open note.

Genuinely one of the most eye-opening and engaging courses I have ever taken. Lectures are designed so you are forced to pay attention as most notes are taken from what he says rather than a set of slides. Sections are extremely helpful in breaking down material, and there are lots of broader concepts that can be applied beyond the course.
