Subclaims¶

q2 i? Inexperienced learners benefitted most from a diagram combined with auditory explanations, but after further intensive training the advantage of audio text disappeared and then reversed, with a substantial advantage of diagram-only instruction. → Kalyuga 2003

Evidence¶

Kalyuga 2003¶

Kalyuga, S., Ayres, P., Chandler, P., & Sweller, J. (2003). The Expertise Reversal Effect. Educational Psychologist, 38(1), 23-31. https://doi.org/10.1207/S15326985EP3801_4

The review attributes this to Kalyuga et al. (2000), experiments on using industrial manufacturing machinery: the same students were followed across training stages, and "Subjective mental load ratings collected immediately after each stage of the experimental training clearly supported a cognitive load interpretation."

"Specifically, when the same students became even more experienced after further intensive training in the domain, a substantial advantage of a diagram-only condition over a diagram with audio text condi- tion was obtained, reversing the results of the first experi- ment."

Studies bearing on this claim¶

Does narration stop helping, or start to hurt, as learners gain expertise? This table gathers the studies behind this claim and the 1 narrower claims that bear on it: 2 distinct studies (1 review, 1 quant-synthesis), q2–q3, 1 of 2 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.

Related Claims¶

• Instructional guidance that helps novices can become redundant or counterproductive as expertise grows. — the general claim this finding bears on, with the studies behind it
• Presentation pacing moderates the modality effect: large under system-paced conditions and not significant under self-paced conditions, where it may disappear or reverse — related
• The review reports that worked examples benefit inexperienced learners but become redundant with increased experience, when problem solving proves superior — related
• Reviews report that the split-attention benefit for novices reverses into a redundancy effect for more experienced learners: Kalyuga et al. (2003) cite Kalyuga et al. (1998) and Yeung et al. (1998), and Ginns (2006) cites Kalyuga et al. (1998) — related
