Sweller, van Merriënboer, and Paas connect instructional design to a cognitive architecture with severely limited working memory for novel information and effectively unlimited long-term memory organised in schemas. Learning changes what working memory can handle by constructing and automating schemas.
Key ideas
The authors distinguish intrinsic cognitive load arising from interacting elements inherent to the material, extraneous load imposed by avoidable presentation or activity, and germane load devoted to processes that contribute to learning. They review instructional effects including worked examples, completion problems, goal-free problems, split attention, redundancy, modality, and variability. Designs help when they reduce unnecessary search and integration while directing capacity toward relevant structure. Effects depend on expertise: information essential for novices can become redundant for knowledgeable learners.
Why it matters
For educators, the framework supports integrating mutually dependent sources, removing decorative or repeated explanations that add processing without value, modelling complex procedures, sequencing element interactivity, and fading guidance with growing competence. Cognitive load is not simply content quantity or subjective difficulty; design decisions should be evaluated through both learner effort and durable performance.
