The review starts from the point that new information must be processed in a working memory of severe limits, and that learning eases the constraint because schemas held in long-term memory allow information to be processed more efficiently. It reports that instructional techniques which reduce working memory load help learners build and automate schemas, but that they work differently depending on expertise. Methods that help novices can lose their value or even hurt more experienced learners. The authors named this the expertise reversal effect and reviewed the empirical research in which it appeared.
Key ideas
The review qualifies cognitive load theory's design advice by tying it to what the learner already knows. The effect is described on its own page on this site.
