Join math professor, Anna Stokke, for conversations with leading educators about the importance of math, effective teaching methods, and debunking common myths about math and teaching. Chalk & Talk is a podcast for anyone interested in education, including educators, parents and students.","last_synced_at":"2026-07-31T20:17:13.151018+00:00","page_url":"https://stenobird.com/podcast/chalk-talk-6066907"},"episode":{"title":"Cognitive load theory and learning math with John Sweller (Ep 67)","slug":"cognitive-load-theory-and-learning-math-with-john-sweller-ep-67","published_at":"2026-03-20T10:00:00+00:00","page_url":"https://stenobird.com/podcast/chalk-talk-6066907/cognitive-load-theory-and-learning-math-with-john-sweller-ep-67","show_page_url":"https://stenobird.com/podcast/chalk-talk-6066907","url":"https://chalkandtalkpodcast.podbean.com/e/cognitive-load-theory-and-learning-math-with-john-sweller-ep-67/","audio_url":"https://mcdn.podbean.com/mf/web/py3z8ezwtm8au2rt/Chalk_and_Talk_Ep_67aoqlk.mp3","summary":"In this episode, Anna is joined by Dr. John Sweller, emeritus professor at the University of New South Wales and the researcher best known for developing Cognitive Load Theory. Together, they explore how cognitive load theory should guide classroom practice, particularly in mathematics. John explains the limits of working memory, how experts and novices approach problem solving differently, and how strategies like worked examples can help manage cognitive load. They also discuss whether productive failure is supported by research and the strong experimental evidence supporting explicit instruction, particularly when students are learning new content. This episode will be extremely valuable for educators, especially math teachers, who want to better understand how students become expert problem solvers and what that means for effective instruction.
