Twenty years after their earlier review, Sweller, van Merriënboer, and Paas update cognitive load theory’s account of human cognitive architecture and instructional design. Novel information is processed in a limited working memory, whereas organised knowledge in long-term memory can guide activity with little apparent load.
Key ideas
The article revisits intrinsic and extraneous load, argues that “germane load” is better treated as working-memory resources devoted to intrinsic processing rather than a separate additive category, and incorporates evolutionary educational psychology’s distinction between biologically primary and culturally acquired secondary knowledge. It reviews established and newer effects involving worked examples, guidance fading, element interactivity, expertise reversal, transient information, self-management, collaboration, and collective working memory. Instructional effects are conditional: the same guidance may assist novices and hinder experts. The authors defend the theory’s testable, experimentally grounded development while identifying unresolved measurement and boundary questions.
Why it matters
For educators, the central design task remains aligning guidance with prior knowledge, limiting avoidable search and split attention, sequencing complex interacting elements, and progressively shifting responsibility as learners acquire schemas.
