I am very happy to post a link to a fabulous site developed by my colleagues in the University of Toronto Libraries.
The Learning Objects and Open Courseware site is a selective list of major repositories of learning objects and open courseware that can be used in classroom teaching and online learning environments.
Learning objects take many forms, including animations, tutorials, videos, journal articles, and quizzes. Educators may include learning objects in their lessons and students may use them to complement and enhance classroom learning.
Open courseware is an entire course, often at the college or university level, that can be accessed without charge over the Internet. Some courses require only a browser to access while others require special software like iTunesU.
