"Doctopus" is a script that makes it easy for students to submit assignments via Google drive, and it allows you to send them feedback. This looks very useful for what we are trying to do will Google Docs!
Interesting - it looks like this company is trying to make a tablet that is tailored for education. I like this idea because the iPads seem to be designed to profit the Apple company, which makes some things (such as the lack of Flash compatibility) a hindrance in the classroom.
This site was put together by Garth Holman and Mike Pennington, 2 teachers who are doing amazing work with getting the students to own the learning. I saw some of their presentations at the BLC13 Conference this past July. They are mentioned in Alan November's book "Who Owns the Learning" so it was a treat to meet them in person at the BLC Conference. Lots of great information and inspiration on their website.
