The OEDb (Online Educational Database) recently posted an incredibly extensive list of the top 100 sites dedicated to educational uses of the iPod. OEDb lists what they perceive to be the best sites for transforming your iPod into a learning device, categorizing the sites into downloadable study guides, podcasts and audio books, tutorials, applications, classroom help, iPod learning support, tools and sites, iTunes U, and more. This is a “must-bookmark” resource for anyone looking to take advantage of the educational benefits that the iPod affords.
