John Sweller On The Foundations And Future Of Cognitive Load Theory

Drew Perkins speaks with John Sweller, Emeritus Professor of Educational Psychology at the University of New South Wales, and Oliver Caviglioli, information designer and former special school principal, about the foundations and future of Cognitive Load Theory (CLT). As one of the most influential frameworks in modern education, CLT provides a scientific roadmap for understanding how human cognitive architecture dictates the way we should—and shouldn't—teach.

The conversation begins with Sweller’s essential distinction between biologically primary knowledge (skills like speech that we evolve to acquire naturally) and biologically secondary knowledge (academic subjects like reading and math that require explicit instruction). Sweller argues that because schools primarily deal with secondary knowledge, the limitations of working memory must be the starting point for any instructional design. A major theme of the episode is the concept of element interactivity. Sweller clarifies a common point of contention: while inquiry-based learning can be acceptable for low-complexity information, it is "catastrophic" for high-element interactivity content where working memory is easily overwhelmed. The guests also explore the "computational advantage" of diagrams, explaining how visual models can offload cognitive strain and make complex syntax more accessible to learners. Finally, the group discusses the "knowledge-rich" foundation required for higher-order thinking. Contrary to the idea that critical thinking is a generic skill to be practiced in a vacuum, Sweller and Caviglioli emphasize that creativity and analysis are only possible when a deep knowledge base is firmly established in long-term memory.
