Below are some links helpful for economics teachers.
1. This blog entry over at Marginal Revolution (a top notch blog, by the way) discusses the use of fiction in teaching economics. The comments are probably the most helpful.
2. This document is a handbook on using the web to teach economics.
3. If you love blogs like I do, this is a guide for using blogs to teach economics. In the past, to really understand economics you had to hang around accomplished economists and hear them talk. The journal articles they write are not enough. Fortunate for young people today, one can hear them talk in their excellent blogs and the superb EconTalk podcasts.
4. eLearning topics (and other good stuff) in economics can be found here.
