Expertise-reversal effect

a. Some methods of instruction that aid more novice students can impede the learning of more advanced students. There are many possible reasons for this effect, which range from a decrease in motivation to a higher cognitive load imposed by mapping a representation to a mental model that is different. It is important to be conscious of varying levels of expertise within the target audience, and to potentially have instruction that adjusts to individual expertise. (Mayer, 2011)
