After the summer session of physics (algebra-based), I have the following comments.

- It seems like every other video has a problem with vector notation. Students often set a vector equal to a scalar. Frustrating.
- Students seem to confuse two standards: The Momentum Principle and Collisions. I have students submit videos for the momentum principle that are just a collision. The key point is that the momentum principle deals with force, time and change in momentum. I guess this is my fault. I offered suggested homework problems from a textbook and it covered momentum and collisions in the same chapter. I guess they thought they were the same thing.
- Students are not very skilled at picking problems to solve. They like the lowest level of something like “mass is 2 and velocity is 3, what is the momentum?”. I tried to help them, but it didn’t seem to work. I showed a bunch of questions in class and had them “rate” them then discuss what makes a good problem. (I think I wrote about that here on my blog).
- I’m still not happy with the “student review”. I want students to watch other student videos – but I don’t know how to implement that.
- Students like to procrastinate. I’m getting a bunch of redos on the last day of submissions. That sucks to grade.
- I hate vertical videos – but I hate videos that are recorded sideways even more. I stopped accepting the sideways videos since they can fix it and send it back to me.
- I try to give meaningful feedback in my responses – but sometimes I just give a grade (score out of 5 points).
- I’m trying to give higher scores. If they do well on the in-class assignment and submit multiple videos that aren’t wrong, I typically will at least give a 4/5.
