Subclaims¶

q3 i2 University students who wrote textbook explanations or verbatim teaching scripts generated more create-level questions than students who wrote study notes. → Sarah Shi Hui Wong 2026 q3 i? Participants generated more create questions for the vanishing songbirds topic than the origins of the moon topic, and the learning method advantage generalized across both topics. → Sarah Shi Hui Wong 2026 (2)

q3 · i2 · causal · r2

Randomized between-subjects experiment (N = 242; notetaking n = 81, explaining n = 80, teaching n = 81); 3 (learning method) × 2 (study topic) ANOVA on create question generation was significant, F(2, 236) = 18.23, p<.001, with "d = 0.57 and 0.91" for explaining and teaching versus notetaking.

"the explaining (M = 1.54, SD = 1.67) and teaching (M = 2.16, SD = 1.93) groups outperformed the notetaking (M = 0.75, SD = 1.06) group, p=.001 and p<.001, d = 0.57 and 0.91, respectively"

q3 · i? · causal · r2

Same experiment's topic main effect on create question generation: more questions for "vanishing songbirds" than "origins of the moon". The learning method × study topic interaction was non-significant, "indicating that the advantages of explaining and teaching generalized across both topics."

"participants generated more create questions for the “vanishing songbirds” (M = 2.06, SD = 1.90) than “origins of the moon” (M = 0.92, SD = 1.22) topic, F(1, 236) = 35.35, p<.001, ŋp2 = 0.13"

Discussion¶

Related Claims¶

• Explaining and teaching both improve basic comprehension relative to notetaking, but do not differ from each other — related
• Teaching (writing a verbatim lecture script) produces better create question generation than explaining (writing a textbook explanation) — a narrower finding that bears on this claim
• Prompting learners to self-explain, one generative strategy, improves learning by a moderate average amount; other generative activities are not tested by the evidence recorded here — a broader claim this one bears on
• Laptop note-takers transcribed more verbatim and did worse on conceptual questions than longhand note-takers in one set of experiments, but a direct replication found no consistent difference in test performance — related
• Learning conditions did not differ in total questions attempted, ruling out differential effort quantity as the source of create-question differences — related
