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? Task distribution across learning goals was more even in the experimental group, with a statistically significant difference between groups (U = 25.5, p = 0.007). → Tsompanoudi et al. 2015

q2 · i? · causal · r2
Task-distribution analysis in the 24-pair evaluation counted tasks per student per learning goal and calculated the difference from an even distribution. The article concludes "the balanced distribution of tasks among pairs achieved symmetry in knowledge acquisition".
"For all learning goals (summative for all projects) there was a greater difference in the control group compared to the experimental group. A Mann-Whitney test revealed that the average difference between the two groups was also statistically significant (U = 25.5, p = 0.007), meaning that system's interventions during DPP had a positive effect on task distribution."
