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.
q2 i? A paired-sample t-test on true-or-false content-comprehension scores found no significant difference between conditions (t = −0.535, p = .597); equivalence was not tested. → Liang 2025

Liang, C., Toyokawa, Y., & Ogata, H. (2025). Optimizing group formation with a mixed genetic algorithm: an empirical study in active reading using marker data. Intern. J. Comput.-Support. Collab. Learn. https://doi.org/10.1007/s11412-025-09452-9
q2 · i? · causal · r1
Six true-or-false instructor-created comprehension questions were administered to 29 students completing both conditions. The t-test was non-significant, with descriptive means of 4.102 (control) and 4.241 (experimental).
"the results of the paired-sample t-test revealed no significant difference between the control and experimental conditions ( t =− 0.535, p = .597 >. 05), despite the mean correction percentage for the control condition (4.102) being slightly lower than that of the experimental condition (4.241)."
Discussion¶
Related Claims¶
- Most students reported using the Wordcloud for group discussion, and Wordcloud use showed a marginally non-significant advantage on content comprehension but no difference on vocabulary gain
- Group summary scores did not differ significantly between algorithm-formed and randomly formed groups on content, vocabulary, or grammar rubrics — related
