Peer assessment at hull

Peer assessment at Hull

Always interested in promoting group work and peer assessment

Started with paper based PA forms for c.60 students

Increasing student numbers made admin difficult

Use technology to solve problems

Worked with Loughborough to develop WebPA (open source version)


Peer assessment model

Peer assessment model

  • Model produced by Goldfinch and Raeside 1990

  • Latest version based on Li 2001

  • Similar model for WebPA developed by Peter Willmott at Loughborough

  • Students produce group product

  • Students assess each other’s contribution to project

  • Marks moderated based on level of marks awarded


Peer assessment scheme

Peer assessment scheme

  • IWF = personal score / average

  • Final mark = IWF*group mark

  • Balances for uneven scoring:

    • Bias factor: scoring of others/average rating

    • Normalisation factor: 1/bias factor

  • Joe scores 47 and average score is 48 (project is 70%)

  • 47/48*70= 68.5%
