You might like to know that webwork has a channel on youtube.
We haven't really added a lot of videos yet, but more are coming from our summer workshops.
Luckily, the Grand Valley State University math department is putting some great tutorial videos for instructors and students using webwork.
I've added them to a playlist on the webwork channel. So, I want to say thanks to the GVSU Math Department, and encourage others to put such videos on youtube or elsewhere. If you do, or if you know about others, let us know and we'll link to them in the webwork channel.
