We have some invitations to the Joost application that is currently in Beta testing. If you are not familiar with Joost (www.joost.com), it is a web based application that will allow you to watch TV over the internet and also allows users to discuss the show while watching the show. The TV channels are provided and maintained by Joost and will include National Geographic, CBS and other channels. My guess is that within months your students will be familiar with Joost, so this is your opportunity to become familiar with this technology before your students do.
If you would like a Joost invite, please respond to this post with a brief summary on how you might be able to utilize this type of application to engage your students.
