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? Students' overall biology knowledge increased slightly from pre-test to post-test but the change was not statistically significant. → Shenghua Zha 2025

Shenghua Zha, Marcy Maulucci Bragdon, Na Gong, Jinhui Wang, Silas Leavesley, Rachel Eaton, Erin Bosarge. (2025). A Case Study of Integrating AI Literacy Education in a Biology Class. International Journal of Artificial Intelligence in Education. https://doi.org/10.1007/s40593-025-00476-8
q3 · i? · design · r2
Paired sample t-test with N = 29: biology pre-test mean 1.52 (SD 1.00), post-test mean 1.90 (SD 1.33), t = -1.28, p = 0.21. The article notes the means indicated "a slight increase" that was not significant; equivalence was not tested.
"However, their overall biology knowledge did not show a significant improvement, though their means indicated a slight increase at the end of the lessons."
