I've come to the conclusion that Sweller's Cognitive Load Theory is the single most important thing for teachers to know – Dylan Wiliam   On this episode Lars speaks with John Sweller, professor emeritus at University of New South Wales in Australia, about the field of cognitive load theory, a research field in educational psychology that John has been developing since the early eighties.  We talk about the cognitive architecture, how working memory and long term memory interact, and how this interaction and its limits make out the foundational insight that is explored in cognitive load theory; how our cognition is shaped by evolution, how David Geary's theory about biologically primary and secondary skills helped John put cognitive load theory into a bigger picture; some of the main effect that have been identified, like element interaction effect, worked examples, redundancy, split attention, and much more.    Recommended books and articles Ashman, G.
