From syllabus:
[These (less than 5 min) screencasts] will cover material that I believe you have been introduced to in earlier coursework and that you need to be comfortable with to engage with more advanced material. I am choosing not to review this material in the lecture because I do not believe that is the most effective way for you to (re)learn it. Instead, I ask that you watch these videos before class (I will post on Canvas by 9 pm the night before). I will then ask if there are any questions about the material in class or plan activities that allow us to practice applying the material together (note that I will take a similar approach to support your work on some assignments as well).
