**I suggest watching this video at 1.5x speed!**
PrairieLearn (http://prairielearn.org) is the next generation online assessment tool. It is open source, built on the latest web standards, and is completely free!
In this video I introduce PrairieLearn and some of the problem types that are possible.
Note: For the physicists and engineers in the audience, yes there is a bug with the circuit as drawn in the video! I am working on fixing it in the sample questions. Thanks!
P.S. I got consent from the student that appears in the video before publishing.
