Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? A Two-Way ANOVA on ranked data found significant main effects of condition (F(2, 262) = 5.037, p = 0.0071) and subject (F(3, 262) = 6.737, p = 0.0002) on learning gains. → Pardos ZA 2024
q3 i? There was no statistically significant interaction between condition and subject (F(6, 262) = 0.901, p = 0.495). → Pardos ZA 2024
Evidence¶
Pardos ZA 2024¶
Pardos ZA, Bhandari S (2024) ChatGPT-generated help produces learning gains equivalent to human tutor-authored help on mathematics skills. PLoS ONE 19(5): e0304013. https://doi.org/10.1371/journal.pone.0304013
q3 · i? · causal · r2
Omnibus Two-Way ANOVA on ranked data from the randomized experiment (N = 274), conducted after Shapiro-Wilk rejected normality. The article also reports "no statistically significant interaction between condition and subject (F(6, 262) = 0.901, p = 0.495)"; no effect sizes are printed.
"we found significant main effects of the condition (F(2, 262) = 5.037, p = 0.0071) and the subject (F(3, 262) = 6.737, p = 0.0002), indicating that the type of hints provided had statistically significant impacts on the learning gains"
Discussion¶
Related Claims¶
- Learning gains from ChatGPT-generated hints were not statistically significantly different from human tutor-authored hints, though ChatGPT gains were numerically higher in all subjects — related
- Learners receiving ChatGPT-generated hints showed statistically significant learning gains compared to a no-hint control in an online mathematics tutoring experiment — a narrower finding that bears on this claim
- Multimedia treatment, prior science level, and unit pre-test level each independently influence electricity achievement, with no significant two-way or three-way interactions — related
