Greg Ashman—author of multiple books including A Little Guide for Teachers: Cognitive Load Theory, deputy principal, and professor—sits down with Susan Lambert on this episode to discuss cognitive load theory and how it applies to how students learn and how to best teach them. Together their conversation covers cognitive load theory, including an exploration of working memory and long-term memory; intrinsic load and extraneous load; biologically primary vs. biologically secondary knowledge; and how to apply these concepts in the classroom. Ashman also provides listeners with helpful advice on ensuring their teaching practices are based on evidence.

Quotes:
“I now know I shouldn't have felt guilty, but I also know that I could have taught that from the outset in a much more structured way where the students would have left understanding the concepts better without wasting time.” —Greg Ashman

“This idea that kids don't need to know anything anymore, they just need to practice skills is really quite a pernicious and damaging idea.” —Greg Ashman

“Think about the teaching methods that you're being presented with. Ask about the evidence and question whether this is really the optimal way of teaching literacy or whatever it is, or whether it's more based on wishful thinking.” —Greg Ashman
