Over the past 18 months Adelaide University has been developing a tool for students to assess the contributions of individual members of their team, as well as themselves. The development of this tool was based on work done at the University of Queensland with Group Peer Assessment and has been developed as a LTI for Canvas.
The Self and Peer Learning Assessment Tool or SPLAT provides an external assignment tool that allows teachers to define a set of criteria that can be used determine a individual weighting factor, more commonly known as a Peer Assessment Factor or PAF score, for each student. This PAF score can be used to underpin a mentoring session with the team, or, if applied to team marks, can be used to generate an individual mark commensurate with contribution. The tool also provides a mechanism for self assessment by comparing score that the student has given themselves over the average of the scores that all the other students have given them. This calculation the SAPA score (Self-Assessment over Peer Assessment) can be used to help the student evaluate their own contributions to team work.
A demonstration of SPLAT was delivered to the APAC group on the 13th April 2018, a recording of this session is available.
SPLAT has been developed using Ruby 2.4.2 and MySQL / MariaDB and is available in Canvas as an LTI. We have made it available as GNU General Public License v3.0 open source software via Github.
User documentation is also available from the Universities Canvas help site.
We would be happy to share our experiences and collaborate with others to continue development of this tool.
