Mathtrain.TV: Episode 55 “Our First Student Screencast from 2007″

Friday, July 24th, 2009

Here is our first official, student-created mathcast from 2007. It is the early version,which is not edited too much. It is a bit longer than most of our math videos.

However, 6th grader “Bob” (not her real name) created this on the spot, with no script and no rehearsal. It was also her FIRST time ever using Camtasia Studio. Camtasia Studio is the screen recording software we use. I thought we should release this as an episode.
