Peer Assessment Experience as Summative Evaluation

Co-evaluation is a didactic technique that develops students’ deep learning and promotes formative evaluation with immediate feedback. In addition, it reduces the teacher's workload, especially in large groups. However, the use of peer assessment results as a measure of summative assessment is still under discussion. This paper describes a peer assessment experience with monitoring of the students' opinion regarding the grade received. Teachers intervened to review the submitted works that aroused the greatest evaluators‧ discrepancy. The results show that about 40% of the ratings issued by peers are not sufficiently reliable as measures of summative evaluation. The calculation of an internal meta-evaluation variable would allow teachers to estimate the quality of each peer assessment and to improve the reliability of the summative assessment.
