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 number of grades given to or received from peers did not significantly predict final project scores. → Jingyan Lu 2012
Evidence¶
Jingyan Lu 2012¶
Jingyan Lu, Nancy Law. (2012). Online peer assessment: effects of cognitive and affective feedback. Instructional Science 40:257–275. https://doi.org/10.1007/s11251-011-9177-2
q2 · i? · associational · r2
In the hierarchical multiple regression (N = 181), entering peer grading measures in step 2 added no significant variance, whereas peer feedback activities added significant variance ("adjusted DR2 = .142, p\ .01").
"the number of peer grading received or given to the model produced no significant change in variance, while adding peer feedback activities did (adjusted DR2 = .142, p\ .01)."
Discussion¶
Related Claims¶
- Receiving positive affective feedback from peers is a significant predictor of assessees' project performance — related
- Giving feedback that identifies problems in peers' work is a significant predictor of assessors' own project performance — related
- Online peer assessment activities account for about 12.8% of variance in project performance, with feedback activities adding 14.2% variance change — reports the opposite
- Cognitive feedback benefits assessors rather than assessees, and weak students do not benefit from receiving more feedback — related
- 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
- Giving suggestions to peers is a significant predictor of assessors' own project performance — related
