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.
