A general education website I found was Carnegie Mellon's Enhancing Education website. The site offers articles and information regarding general tips for educators including tips on designing and teaching your own course. The information given is very practical, pertaining to efficient use of time, knowing your students, and multi-cultural education. The fact that it's from Carnegie Mellon, a university known to be credible, ensures that the information on the site is trustworthy.
