iTunes U

iTunes U puts the power of the iTunes Store to work for colleges, universities, and other education organizations, so students can easily search, download, and play education content just like they do music, movies, and TV shows. Learning no longer happens only at a desk. Students now expect constant access to information, no matter where they are. Which is exactly why more and more faculty are using iTunes U to distribute digital lessons to their students. Audio and video podcasts let students study at their own pace, wherever and whenever they want.
iTunes U, part of the iTunes Store, is a free educational media available to students, teachers, and learners. With over 100,000 educational audio and video files available, iTunes U has quickly become the engine for the mobile learning movement. It puts the power of the iTunes Store in the hands of qualifying universities so they can distribute their educational media to their students or to the world. Teachers are using iLife and iWork applications on the Mac to create customized educational materials, such as language lessons that students can listen to on the bus or at home. And with the help of tools like Podcast Producer and Wiki Server IT professionals at your school can help you produce and distribute all kinds of multimedia content on iTunes U.
Administrative access is integrated with Apple ID, and so for student access their own account they need a password for the iTunes U site. This also enables the student to create and manage the content available on the site, while controlling who can access and download resources from it.
I think this is a great idea so now we can all have access to the classroom information anywhere we are. So there are no excuses to teachers for not getting the assignments anymore if the student was sick or out a day. This also helps the student so that they do not get behind in the class.
