I am ready to go to the Apple reception this evening. Part of the festivities will be Apple's big splash at NECC. That splash is iTunesU-K12. iTunesU-K12 should debut within the next few hours with content from between 7 and 9 states. Utah is one of the states that will be debuting on iTunesU-K12. I have been working with the Utah group that has been putting together the states efforts on this project.
I believe this project will be somewhat of a game changer. Here K12 ed will have a central gathering place for resources, be they audio, video, text-based, etc. Now I can hear the catcalls and boos coming already. "Here's Apple trying to take control of our content!" I don't believe that this is what it is about at all. Look at what iTunesU has provided for Higher Ed. There are many prestigious universities sharing their content. It is not under Apple's control, they are merely providing the vehicle. Such is the case with iTunesU-K12 as well.
Go to the iTunes store, click on iTunes U, then look for the K12 listing in the bottom left column.
I personally can't wait to see the resources gathered there.
