Digital Peer Grading in Group Learning: Empirical Insights and Best Practices

The impact of digital peer grading on group learning dynamics in project-based courses in higher education is studied using the web-based tool Peer Grading Tool (PGT). Following an action research approach, this study, which was conducted over two years across 20 courses, examines the use of PGT for both grade influencing and reflective peer assessment. Empirical data collection from students and lecturers led to interesting findings. The results reveal nuanced insights into the contextual suitability of PGT, highlighting factors, such as group size, familiarity among members, heterogeneity, voluntariness, and robust feedback culture. The research also highlights potential challenges and emphasizes the importance of a pre-existing feedback culture to mitigate negative impacts. The findings contribute to the derivation of actionable recommendations and best practices for the implementation of peer grading campaigns in higher education.
