Creating educational videos for Youtube (cheaply)

This post is from Wes Fryer's blog. It details a presentation by Marty Brandl on producing inexpensive and yet meaningful math lessons on Youtube. One of the things that was most intriguing to me about this was how little technology went into producing these lessons. Some of the text here is a little difficult to read, but it is easy enough to get the important part of the presentation, that these lessons were produced with a cheap microphone and a $35 Wacom pad. Check it out here: http://www.speedofcreativity.org/2012/03/09/creating-educational-videos-for-youtube-by-marty-brandl-swwc2012/ and then have a look at what Marty Brandl has posted on Youtube here: http://www.youtube.com/profile?user=mbrandl11&view=videos

One of the things that struck me the most about this approach is that it does not rely on any elaborate graphics or animation. From the standpoint of reducing cognitive load through distraction, this is a marvelous approach!
