AAPT presentation on value of Masterclass video conferences

I'm giving a brief "talk" at the 2013 Summer AAPT physics conference in Portland about the value of students doing a video conference as part of their U.S. Masterclass experience.  Masterclass is not only about understanding high energy physics content, but it also communicated the attitudes and joys of doing physics.  But it is hard to communicate in words some of this.  So I decided to share some "screen captures" from the video conferences showing a few of the gestures and facial expressions.  Unlike staged photographs where everyone pastes on a smile at the "say cheese" instruction, these images catch spontaneous expressions in an ongoing, more than half hour long session at the end of the day when the students are rather tired and ready to head home.  Below are two such images.
