The design of open learner model to improve interaction of peer assessment in online learning

Abstract

Peer assessment has been reported as an effective collaborative learning approach. However, it is very difficult to encourage students to engage in reviewing activities. This study puts forward an open learner model approach that helps students' peer interaction in the context of online peer assessment. A framework is proposed which structures and represents the information of peer interaction including Issue, Position, Argument and Feedback. These characteristics aim to support students to recognize and target problem areas. Once targeted, on the one hand, the system can suggest strategies to help students collaborate more effectively with their peers, maximizing students' learning performance. On the other hand, students can access peers' learner models and look for feedback on their work in a group. The result will provide strategies and suggestions to encourage peer interaction in the context of online peer assessment effectively.
