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 i3 Students using BEETLE II showed substantially larger pre- to post-test learning gains than no-training control participants, with the article reporting an effect size of 1.72. → Dzikovska 2014

q3 · i3 · causal · r2
System evaluation comparing BEETLE II training against a no-training control that completed pre- and post-tests separated by distractor tasks. The article reports "effect sizes of 1 .72" for pre- to post-test learning gains, describing the curriculum as highly effective.
"Our curriculum is highly e ffective, achieving effect sizes of 1 .72 when comparing pre- to post-test learning gains from our system to those of a no-training control group."
