The Firehose Effect

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 shifting the burden of proof, overwhelming people with endless references, credential deflection, and denying that poor practice exists at all.  She also offers practical advice for parents and educators on how to counter these tactics and spot and stop the spread of bad ideas in education.

This is an essential conversation for anyone trying to push for better practice in schools and navigate resistance along the way.
