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? The average difference in contribution rates within pairs was 0.243 for the control group and 0.165 for the experimental group, but the difference between conditions was not statistically significant (p > 0.05). → Tsompanoudi et al. 2015

q2 · i? · causal · r1
Contribution-rate analysis of logged code submissions across five projects in the 24-pair evaluation, calculating each student's contribution as the ratio of typed code to total code. The article states the Mann-Whitney test "indicated that the difference between control and experimental condition was not significant (p > 0.05)".
"It was found that the control group had an average difference of 0.243, while the experimental group had an average difference of 0.165. Values within the range 0 and 0.2, namely a participation rate between 40% and 60%, are sufficient to indicate symmetry in contribution."

Learner Variables¶
- Collaboration — outcome: instruction changes it
