Hi Steve, When I first trained, it was with a major in Economics but I have never taught it except for commerce at the middle levels of schooling. However, I got put into teaching computers and just love being there. Web2.0 has had some amazing outcomes for us.
With your work in Technology at United World College, I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based platforms, have a bunch of features and free basic service. Here’s a public class recording conducted by Nellie Deutsch on Technology Integration.
