Cognitive load refers to the amount of information presented and how well that amount compares with the size of working memory. Optimal load varies, based on the level of learner expertise. Novice learners with limited prior knowledge are more likely to process simple, sequential structures with limited threats to overloading memory. Expert learners, on the other
hand, are able to accommodate richer, more complex information loads due to their developed schemas or knowledge representations that make integration of new information possible. Optimally, the designer’s task is to structure information that fits within existing
schema (i.e., prior knowledge). Individual differences in both prior knowledge and effective working memory size are particularly troublesome when designing materials to be used by wide ranges of learners.
