Another place to find universities sharing lectures and courses online is through YouTube's education channels. Finding educational material from universities on YouTube does require sifting through some garbage, but if you're willing to do that you can find some good stuff like the Penn State, Harvard, and Stanford YouTube channels.
Applications for Education
iTunes U and YouTube's university channels offer some good resources for personal learning both for you and for your students. If you're a high school teacher and have students that are interested in learning more about a particular topic, consider referring them to iTunes U. Most students are familiar with iTunes, but they might not know about iTunes U. And remember, you don't have to have an iPod to access podcasts.
