Colleagues from the Poincaré Institute and I will be presenting work on teachers and mathematical modeling at the National Council of Teachers of Mathematics 2013 Research Presession, April 15-17 in Denver, Colorado! This work explores what criteria teachers use to define what constitutes a mathematical model, how that criteria changes depending on context, and what that means for teacher preparation and classroom practice.
