Replace Cameras and Laptops with Smartphones?

Industry Pitching Cellphones as a Teaching Tool:
"On Tuesday, Digital Millennial will release findings from its study of four North Carolina schools in low-income neighborhoods, where ninth- and 10th-grade math students were given high-end cellphones running Microsoft’s Windows Mobile software and special programs meant to help them with their algebra studies.

The students used the phones for a variety of tasks, including recording themselves solving problems and posting the videos to a private social networking site, where classmates could watch. The study found that students with the phones performed 25 percent better on the end-of-the-year algebra exam than did students without the devices in similar classes."

This article is mainly about the (potential) benefits of smartphones. However, self-evaluation through VIDEO has long been proven effective. This component could certainly be executed with many different phones - and would not require Windows Mobile.
