first video: the quadratic formula

The first video is up on youtube! It's a two-parter on the quadratic formula:

part one | part two


I learned a few things putting this together:
  • youtube currently supports higher quality video than google video, but with a 10 minute limit
  • google video allows longer videos, but the quality is not good enough for typical slides or board writing
  • it takes a while to compress and upload videos!
Despite the 10 minute limit being cumbersome, I think we might be able to use this as a constructive constraint, in that it enforces short videos which students are more likely to actually watch. I've seen first-hand how challenging it can be to compress a certain amount of material into a short time-limit -- my first video is about 20 minutes! I'll have to work on this for my own video contributions.
