There are many ways to make engaging and highly effective videos for education, including live action, voice-over imagery, animation, stop action, and others. The newest entry to the list is the Lightboard, invented by Michael Peshkin at Northwestern University. This format uses a studio shot of the instructor speaking while writing on a board, similar to a live class with a blackboard. But the twist is that the instructor does not turn his or her back on the audience to write. The instructor writes on a glass pane between himself or herself and camera, allowing the instructor to speak directly to the audience while writing. The effect is quite engaging.
