I record the whole class for kids that are absent or for anyone who wants to review an old topic as window media files (*.wmv) using Smart Recorder and store them on my ftp site. That's period 1 Calculus BC.
Now, I started recording the first 10 minutes of my period 9 Calculus BC class as a quicktimes (*.mp4) using http://screencast-o-matic.com for youtube.
