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? The high-dose group improved significantly in ICT subject knowledge [t(25)=3.537, p=0.002]; the low-dose group's gain was not statistically significant [t(26)=0.844, p=0.406]; pre-test scores did not differ between groups [t(51)=0.642, p=0.524]. → Pengjin Wang · Fan Chen · Deliang Wang · Gaowei Chen 2025

q3 · i? · causal · r1
Paired-samples t-test of pre–post ICT subject knowledge in a 3-month case study with 53 second-grade students; high-dose means rose "from the pre-test (M = 4.77, SD = 1.18) to the post-test (M = 5.65, SD = 0.56)" [t(25) = 3.537, p = 0.002], statistically significant. Low-dose gain was not significant [t(26) = 0.844, p = 0.406]; equivalence was not tested.
"for the high-dose group, there was a statistically significant enhancement in ICT subject knowledge, with scores rising from the pre-test (M = 4.77, SD = 1.18) to the post-test (M = 5.65, SD = 0.56) [t(25) = 3.537, p = 0.002]."
