The quality of peer assessment in a wiki-based online context: a qualitative study

Abstract

Peer assessment (PA) provides opportunities for authentic assessment, autonomy and collaboration. Several authors advocate that students can benefit from PA and put forward the effects of PA on the students’ learning outcomes. Questions concerning the validity and reliability of PA and PA competences are also addressed by different researchers. This qualitative study is part of a wider project that seeks to develop and test evaluation and assessment strategies in online contexts. In a doctoral module, PA was used for summative and formative purposes. Formative PA aimed to give feedback about the ongoing group work, but also to increase online interaction between the different groups of students. The main module task was to write a literature review, about a selected topic, using a wiki. Criteria and indicators to assess the literature review were negotiated with the students. Different criteria were used to assess the quality of PA, such as, the use of the negotiated criteria, the adequacy of the chosen vocabulary or the provision of constructive feedback. The results show that overall the quality of PA can be improved. Groups did not provide sufficient criticism, questions and suggestions for improvement.
