Free K-12 Content and iTunes University
http://www.apple.com/itunes/download/
K-12 education has a category all its own within iTunes University. It includes professional development, curriculum resources, best practices, and samples of student work. The idea is to bring state and district resources to K-12 educators within their own states, and to provide nationwide and global access to educational content, curricula, learning materials, news, best practices, and other resources. This comprehensive collection of quality digital content offers teachers and students a single location to access resources on topics from Florida history to the Navajo language to nano technologies,” said Mary Ann Wolf, executive director of SETDA. “The new K-12 resources on iTunes U address the critical need to engage students through technology-based resources in the core curriculum areas." iTunes, a free software download for both Macs and Windows, is required.
