Implementation of PeerWise
Which activity is most strongly associated with exam performance?
DV: Exam score
IV: Number of answers or comments made
Example: Physics 1A 2012-13
Is writing quality comments associated with higher exam performance when controlling for other factors?
Dependent Variable:Exam score
Independent Variables: No. comments coded > 4
Pre-test mark (FCI)
Building the model
The model predicts that each new high quality comment, is associated with a 0.35% increase in exam score.
The minimum 6 comments associated with a 2% increase .
The mean of 14 comments associated with a 5% increase.
Total engagement with PeerWise far exceeded minimum requirements
Across all disciplines, writing meaningful comments has a significant, positive association with exam performance when controlling for other known influential factors
Especially interesting given that PeerWise requires minimal instructor intervention; that PeerWise is only worth ~4% of the total course mark; and that providing feedback is only one aspect of the PeerWise assessment
