Get on the Mathtrain

Eric Marcos has a nice learning site going using podcasts to deliver his lessons.  I appreciate his use of technology to share his teaching.  Go to the iTunes store for a free subscription to the podcasts, subscribe via RSS, or simply bookmark the Mathtrain site.  He also has a site called Mathtrain TV.  Much more is available there.  You can follow him on Twitter as well.  The podcasts are short, sweet, and to the point.  They make great supplements to your lessons.
