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? Quiz scores improved after the learning session and later declined, with a significant positive linear and significant negative quadratic effect of timepoint in a mixed-effects polynomial regression. → Cetron 2026

Results analysis of two written fact-retrieval quizzes (linear forces and moments) administered at four timepoints to 50 novices, using a mixed-effects polynomial regression with random intercepts by participant ID. The article reports "a significant positive linear effect" and a "significant negative quadratic effect" as printed; no effect size is reported, so no magnitude is asserted.
"On average, there was a significant positive linear effect of experimental timepoint (𝛽 = 0.36, SE = 0.13, p = 0.006), coupled with a significant negative quadratic effect (𝛽 = -0.82, SE = 0.12, p = 1.08x10-10)."
Discussion¶
Related Claims¶
- Lab-based versus textbook-based instruction produced no significant difference in novices' quiz learning over the experiment's timecourse — related
- Quiz accuracy declines from immediate to 1-week delayed testing regardless of text medium — related
- The self-study-before-discussion advantage persisted at one-week delayed tests, with lecture-condition scores declining over time while self-study-condition scores remained stable — related
- Student activity declines consistently from the first to the last learning unit across all three outcome groups — related
- Both experimental and control classes scored significantly higher on the second conditional quiz than the first — related
