Peer assessment of assignment

We have appraised the effectiveness of peer assessment of assignments in aiding student learning at the University of Southern Queensland. Each student was randomly allocated two peers' assignments for double-blind assessment. A marking rubric was provided. More than 95% of the class participated in the process. Students' peer-assessment work was evaluated by the instructor. Over 80% of the students assessed their peers satisfactorily. Students' learning experiences, attitudes and behavior towards the peer assessment system was surveyed. More than 60% of the students considered peer assessment a useful learning tool. However 25% remained unconvinced. Most of these students either fully or partially subscribed to William Perry's position of 'dualism'. About 55% found the feedback from their peer's useful. Surprisingly, >69% of the students believed that the peer assessment had nothing to contribute towards a students' community of practice.
