iTunes You

In their bid to put iPads in every classroom, Apple just opened up iTunes U to every teacher.  Using the free iTunes U Course Manager, teachers can create up to 12 courses,  uploading their own content or taking advantage of over 500,000 resources already available.

The courses you create are private, so you will need to invite students to join, but it's as easy as emailing a link.  If you want the course to be public, you will need to go through the usual Apple vetting process.

This is a big deal for anyone wanting to use mlearning or the flipped classroom model, and takes a step towards embedding Apple more firmly into the classroom environment, whatever you may think of that.
