q2 i? Instructional procedures benefiting novices processing high element interactivity information become counterproductive with increasing expertise as elements become embedded in long-term memory structures. → Sweller 2019

q2 · i? · review · r2

This narrative review attributes the expertise reversal effect to Kalyuga et al. (2003, 2012): pre-1998 CLT effects obtained with novices shrink, vanish, or reverse as expertise rises because element interactivity falls via the environmental organising and linking principle.

"As a consequence, with increasing expertise, the above effects first decrease in size, then disappear, and can eventually reverse (Kalyuga et al. 2003, 2012)."

Discussion¶

Learner Variables¶

• Prior Knowledge — moderator: an instructional effect differs with it

Related Claims¶

• Learners with high prior knowledge benefit more from segmenting in retention performance than learners with no or low prior knowledge — the general claim this finding bears on, with the studies behind it
• Segmentation Benefits Shrink With Expertise — a narrower finding that bears on this claim
• Instructional guidance that helps novices can become redundant or counterproductive as expertise grows. — a narrower finding that bears on this claim
• Cognitive Load Management — related
• Worked-example guidance becomes less effective as learner expertise increases. — a narrower finding that bears on this claim
• Minimal guidance is less effective for novices than explicit instruction — related
• In one meta-regression, the PS-I fidelity benefit tended to shrink for interventions spanning only a few hours, a marginal interaction (p = .055) — related
• The article analyzes the consequences of explaining the various cognitive load effects in terms of element interactivity — related
• The expertise reversal effect relies on changes in relative levels of element interactivity due to changes in relative levels of expertise — a narrower finding that bears on this claim
• Expertise reversal: high-guidance worked examples become ineffective or detrimental once learners have developed cognitive schemata — possibly the same claim (merge candidate)
• The worked example effect is explained by reduced element interactivity relative to problem solving, and reverses with expertise — possibly the same claim (merge candidate)
• The review reports that the isolated-elements mixed instructional method benefits novices but the benefit disappears for experienced learners, and that the imagination effect reverses with expertise — a narrower finding that bears on this claim
• Split-attention and redundancy effects occur for high element interactivity material but disappear for low element interactivity material — related
• The element interactivity effect relies on changes in element interactivity due to changes in the type of material being learned — related
• Element interactivity and expertise reversal effects: cognitive load effects diminish and may reverse as expertise increases because known elements chunk into single elements — possibly the same claim (merge candidate)
• Design guidelines beneficial for novice learners can be ineffective or even detrimental when applied to experts (expertise reversal) — possibly the same claim (merge candidate)
• Expertise reversal effect: instructional aids effective for low-knowledge learners hinder high-knowledge learners across all three layers — possibly the same claim (merge candidate)
• Expertise reversal effect: learners with developed fluency do not benefit from unnecessarily explicit instruction and benefit more from open problem-solving approaches — possibly the same claim (merge candidate)
• On the delayed test, a significant three-way interaction showed a worked example effect for high element interactivity material and a generation effect for low element interactivity material for novices — a narrower finding that bears on this claim
• CLT-based instructional design is applied to very high element interactivity material (per Pollock, Chandler, & Sweller) — related
• The thesis hypothesises that with increasing expertise the worked example effect may be eliminated or reversed while the generation effect remains robust — a narrower finding that bears on this claim
