Dr. Medina's paperless class hub.
If you have a few minutes, you should check out this blog post from an old professor of mine, Dr. Cynara Medina. I had her for Media Audiences last semester, and she was pretty savvy in her use of classroom tech, as you can see from that list of her favorite web apps. This semester though, she's pushing for an entirely paperless classroom with the help of Google Apps. Pretty cool. I just wish more classes were run like this. Let us know in the comments about what apps and technologies your professors are incorporating into the classroom.
