Whether the ten learning techniques help students of different prior ability equally.

Subclaims¶

q3 i2 Across all techniques, the mean effect was d = 0.47 for low-ability students (58 effects, 13 studies) and d = -0.11 for high-ability students (28 effects, 6 studies); high-ability students showed negative effects for interleaved practice and summarization. → Donoghue & Hattie 2021

Evidence¶

Donoghue & Hattie 2021¶

Donoghue, G. M., & Hattie, J. A. C. (2021). A Meta-Analysis of Ten Learning Techniques. Frontiers in Education, 6, 581216. doi:10.3389/feduc.2021.581216

q3 · meta-analysis (19 studies reporting ability) · i2 · medium effect for low-ability students, d = 0.47; d = -0.11 for high-ability · n=19 studies · quant-synthesis · r?

Only 6 of the 242 studies examined high-ability students and 13 low-ability students. Across techniques, low-ability students gained d = 0.47 (SE 0.15, 58 effects) and high-ability students d = -0.11 (SE 0.10, 28 effects), with negative effects for interleaved practice and summarization in the high-ability group.

"Across all techniques, the mean effect on High ability students was -0.11 (SE = 0.10, N = 28) for Low ability students was 0.47, SE = 0.15, N = 58."

Studies bearing on this claim¶

Do structured techniques and guidance help lower-ability learners more than higher-ability ones, narrowing the gap? This table gathers the studies behind this claim and the 7 narrower claims that bear on it: 10 distinct studies (4 quant-synthesis, 4 causal, 2 review), q2–q4, 3 of 10 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.

Discussion¶

This rests on 19 studies and is consistent with expertise-reversal accounts, where support that helps novices is redundant or harmful for more knowledgeable learners. It is a reason to adapt technique prompts to prior knowledge rather than a verdict on any one technique.

Learner Variables¶

• General Cognitive Ability — moderator: an instructional effect differs with it
