Welcome to the Mathtrain.com with Mr. Marcos podcast.

We changed the name to Mathtrain.TV with Mr. Marcos.

This is a repeat of Episode 0, our first podcast.  In this show, we briefly introduce you to what the focus of this podcast will be – – namely, student-created mathcasts (video math lessons).  For the most part, Mr. Marcos’ middle school students will be leading the mathcasts via a Tablet PC and Camtasia Studio.

We like the “kids teaching kids” model.  The students are from Lincoln Middle School, in Santa Monica, CA.
