U.S. News and World Report has an E-Learning Guide, which explores distance learning, e-learning, and technology.
Here is the tinyurl: http://tinyurl.com/blea9b
A description taken from the web site: "U.S. News and World Report has gathered information from more than a thousand traditional and virtual universities. We have a searchable directory of graduate and undergraduate providers offering courses, certificates, and degrees via the Internet and other distance learning media."
This web site is definitely worth exploring before signing up for any distance education program.
