video's as educational tool

Today I went to a demonstration of a video-recording system. The purpose is that the university develops a collection of taped lectures.
It is a trial about the equipment.

I might want to do different things: make short tapes about the various interactions and presentations formats we're using in P&P, and then store them , maybe including voice-over comments.

I got the advice to see what Joke Oosterhuis had done previously. I knew her as a person, but not her site.
