They also answer questions from listeners that were submitted during a livestream version of the episode. Chalk & Talk website: www.chalkandtalkpodcast.com This…
In this episode, Anna is joined by two elementary school teachers from California who are appearing anonymously so they can speak candidly about their experiences. Both teach at a school where math achievement has remained consistently low. After watching many of their students struggle with the curriculum they were expected to use (Illustrative Math), they began exploring research, learning about the science of learning and evidence-informed teaching practices, and rethinking what they had been taught about how children learn math. They changed the way they taught math and the results were…
In this episode, Anna is joined by returning guest Dr. Brian Poncy to discuss math fact fluency and whether improving students’ fluency with basic number operations leads to better overall math achievement. Brian shares new results from the first year of a large implementation of the free Facts on Fire program in a Texas school district. They discuss what the data shows, how the program has evolved based on teacher feedback, and what educators are saying about it. They also revisit five evidence-based reasons why fluency—being able to do math both accurately and effortlessly—matters. With a…
In this episode, Anna is joined by returning guests Dr. Nidhi Sachdeva and Dr. Paul Kirschner, authors of the upcoming book Becoming an Expert Teacher: Deliberate Practice for Effective Teaching.

In this episode, Anna Stokke continues the conversation from the previous episode on what happens when requests for evidence are dismissed with the phrase “research shows.” She is joined by Thomas Briggs and David Shuck from the Center for Educational Progress to explore why ineffective or unsupported practices persist in education. Thomas and David introduce an important distinction between misunderstanding and conviction: sometimes educators genuinely believe they are following best practices, while other times evidence is ignored or dismissed due to ideology. They discuss examples…
In this episode, Anna Stokke explores what to do when a math program or education initiative doesn’t seem to work, but you’re told ”research shows” that it does. Drawing on her personal experience as both a parent and educator navigating “research shows” claims, Anna explains how parents, teachers, and advocates can ask for evidence, evaluate what counts as credible research, and respond when weak claims are presented with confidence. This episode is based on a presentation she gave at researchED Toronto in 2025. Anna unpacks common tactics used to shut these conversations down, including…
In this episode, Anna is joined by Professor Joanna Barbousas, Pro Vice-Chancellor of Education, Impact and Innovation, and Dean of the School of Education at La Trobe University in Australia.
