Science of Math: The movement everyone's talking about with Sarah Powell (Ep. 65)

Chalk & Talk

About

In this episode, Anna is joined once again by Dr. Sarah Powell, a professor at the University of Texas at Austin whose research focusses on supporting students with math difficulties. They respond to a recent NCSM statement criticizing the Science of
Math movement.


Anna and Sarah unpack what the Science of Math is and why high-quality evidence matters.  They address misconceptions about explicit instruction and “one-size-fits-all” teaching and explore why math instruction deserves the same scientific scrutiny as reading instruction. This episode is a must-listen for educators, school leaders, policymakers, and parents navigating the current math education landscape.
