Eric Marcos is a mathematics teacher at Lincoln Middle School in Santa Monica, CA. Eric integrates technology through a student-centered “kids teaching kids” model. Using screencasting software, Eric’s students create math video tutorials, which are used in classroom instruction and for the class podcast.
