Bare with me here, I almost feel as if I am starting to sound repetitive in some of my blogs. iTunes University is a fabulous resource. It is basically free educational media available to students, teachers, administrators, or anyone wanting to learn. Teachers can create lessons and share them on iTunes for anyone's benefit or they can make them available only to their students. The cool thing is that you can pull up lectures or materials missed right on your ipod.
There are other advantages of iTunesU as well. Teachers and students can post podcasts, share media tools, and schools can share the benefits its school has to offer and use that for recruiting purposes.
