The validity and students' experiences of peer assessment in a large introductory class of gene technology

Although studies have examined the validity of peer assessment, research including students' own experiences of peer assessment is scarce. The present study aims to improve assessment practices in a context with a highly traditional assessment culture. The aim is first to examine the validity of peer assessment by analysing the compatibility of student and teacher evaluation and explore the differences between minor and major students' evaluations. Second, the study examines students' experiences of peer assessment. Peer assessment was implemented in a large bioscience course with 79 student participants. After the peer assessment, the students provided feedback. The results indicate that student subject understanding can be supported through a proper assessment practice. Peer assessment was successful in an introductory class with minor and major students, and most students experienced it as supportive of their learning.
