Software developer Mike Matas demos the first full-length interactive book for the iPad -- with clever, swipeable video and graphics and some very cool data visualizations to play with. The book is "Our Choice," Al Gore's sequel to "An Inconvenient Truth."
Describes teacher observation for the 21st century. There is a good TED talk with Bill Gates that describes this. Seems scary, especially the full-time intrusion on the teacher, but the ideas are interesting. What if we gave teachers the opportunity to videotape themselves or have the classroom videotaped for a day and let them watch the tape? Just to let them reflect. Wouldn't that be valuable?
