Expertise Reversal Effect

Shrink Definition

The expertise reversal effect is the finding that teaching methods helpful for beginners can become useless or harmful for experts, and vice versa. Detailed guidance that helps novices can bore and burden experts who no longer need it. What supports learning depends on how much the learner already knows. Good instruction adapts as expertise grows.
