Hi Ian! Hope you're enjoying the winter break. I was wondering if you, your colleagues, or students would be interested in a Vocab Video Contest @ MIT university. We'd really like to get Colorado students involved. Please let me know! Thanks!
With your work in Instructional Technology I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based, have a bunch of features and free basic service. Both technologies might be helpful to the teachers and students in your school district.
