Enhancing Student Performance: The Impact of Quality Feedback in PeerWise System

This study examines the role of student feedback in the PeerWise system and its correlation with exam performance. Analyzing data from courses like Physics 1A (2012-13), we assess how the number and quality of comments influence exam scores. Findings indicate that each high-quality comment is linked to a 0.35% increase in exam scores, with a minimum of six comments correlating to a 2% increase. Overall, meaningful engagement in PeerWise showed a significant positive association with academic success, despite minimal instructor intervention.

  1. The benefits of giving feedback: investigating patterns of student exchanges over the PeerWisesystemAlisonKay and Judy Hardy

  2. Implementation of PeerWise

  3. Comment coding

  4. Comments examples

  5. Which activity is most strongly associated with exam performance? DV: Exam score IV: Number of answers or comments made

  6. 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) Scottish Major Gender

  7. 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.

  8. Conclusions 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
