Here are four podcasts worth listening to over the weekend. Wicked Decent Learning has a special guest, Mark Spahr, in studio in their most recent podcast. This week the guys discussed team teaching. As always the podcast is an entertaining and thought provoking hour-long podcast.

Ron Kroetz’s most recent podcast on Tech Teacher Live is a short episode about some of NASA’s most recent efforts to get schools and students excited about space exploration.

On Tech Talk 4 Teachers, Tom Grissom, discusses developments in the low-cost computing market specifically the ASUS Eee PC. Tom also reviews a cool new service called Text 2 Mind Map that allows users to create mind maps from text messages displayed on manipulated on a SMART board.

Finally, a podcast that I’ve followed for months, but never shared here is WebbAlert. Webb Alert is a daily podcast that discusses developments in the Internet industry. There is something new every day and each episode, in five to six minutes, covers a wide range of Internet and technology developments.
