Subclaims¶

q3 i? Across two experiments, increasing the utility value of distinguishing as a task goal and providing conditional knowledge that distinguishing and detection differences matter fostered learners' use of interleaving. → de Bruin 2025 q3 i? Providing the conditional knowledge that interleaving highlights differences alone did not affect interleaving use, suggesting learners were already aware of this. → de Bruin 2025 (2)

q3 · i? · review · r2

Two experiments by Abel et al. (2024) investigating why learners scarcely apply interleaving with easily confusable categories, as summarized in this editorial. "Combining two factors" — utility value and conditional knowledge — "fostered learners’ use of interleaving." No effect size is printed.

"Together, their two experiments showed that combining two factors—increasing the utility value of distinguishing as a task goal and providing learners with the conditional knowledge that distinguishing and detection differences matter—fostered learners’ use of interleaving."

q3 · i? · causal · r?

Same two-experiment study by Abel et al. (2024), reporting the null effect of the isolated conditional-knowledge factor on interleaving use; the editorial attributes this to learners' existing awareness. No effect size is printed.

"Providing the conditional knowledge that interleaving strategies highlight differences did not affect the use of interleaving, suggesting that learners were already aware of this."

Discussion¶

Related Claims¶

• In Experiment 1, learners interleaved more only when high utility value of distinguishing was combined with instruction that differences matter, with the two factors interacting rather than showing main effects — possibly the same claim (merge candidate)
• Even when motivated to distinguish and informed that differences matter, learners in Experiment 1 blocked 68% of their study sequence choices — related
• In Experiment 1, metacognitive preference for interleaving showed main effects of utility value and differences-matter instruction without an interaction — related
• In Experiment 1, the extent of informative interleaving did not correlate with category assignment performance, which the authors interpret as a utilization deficiency — related
• Labelling mushrooms as poisonous versus edible successfully raised the perceived utility value of distinguishing, interest, and perceived authenticity in Experiment 1 — related
• Effort investment is driven differently in CLT (data-driven, task difficulty) versus SRL theories (goal-driven, motivation) — a broader claim this one bears on
• Interleaving Improves Discrimination — related
• GenAI-supported utility value reflection produced more favorable development of perceived utility value than GenAI-supported cognitive learning strategy prompting in secondary students — related
• Two types of equation in school mathematics are easily confused and the confusion can be avoided by suggested means — related
