We've posted about the 2011 Montana Teacher of the Year, Paul Andersen, before because he just might be the coolest teacher of any subject we've ever encountered. He's embraced social media to help his students gain help after school hours are done, and with this particular video he solicits questions from over 20 countries about AP Biology final exams!

This video is much longer than his typical online tutorial, but it's pretty interesting for those of us who were science geeks back in the day. Paul Andersen teaches science at Bozeman High School.

Perhaps watch it over your lunch hour while you're slaving away at your job that has nothing to do with the field you were so fascinated by when you were in high school...it's smarter than wasting an hour on Facebook.
