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? Students' online collaboration and evaluation activities explained about 12.8% of project performance variance, and peer feedback activities added a significant 14.2% variance change beyond controls and grading. → Jingyan Lu 2012

q2 · i? · associational · r2
Hierarchical multiple regression (N = 181) with prior Humanities and Computer Literacy scores as controls (ΔR² = 0.037, p< 0.05). The article reports online activities "accounted for about 12.8% of project performance variance" and feedback added adjusted DR2 = .142, p\ .01.
"The multiple squared correlation coefficient was .128 indicating that students’ online collaboration and evaluation activities accounted for about 12.8% of project performance variance."
Discussion¶
Related Claims¶
- Peer grading behaviors do not significantly predict project performance for assessors or assessees — reports the opposite
- The quality of feedback students give peers predicts gains in their own work, but no recorded study isolates a causal benefit of the assessor role — related
