TVO's Search Engine discusses Mobile Devices in the Classroom.
Search Engine is a Canadian Podcast I listen to. Recently there's been a couple of episodes interviewing teachers regarding the use of technology in the classroom. Specifically mobile devices such as smart phones. The first Podcast was recorded as a response to comments made by Ontario Premier Dalton McGuinty. It is an interview with Royan Lee, "a teacher who's not afraid of technology".

The second Podcast is a response to the first by another teacher,Anthony Marco, and nicely counterpoints the first Podcast.
