Secondly, as the assessor, the more assessment students provided to their peers, the more the originality of their reflective writing improved; as the assessee, the more critical assessment students received from their peers, the more the elaboration of their reflective writing improved. Lastly, students in large size subgroups are at the core of the network, and they benefit more from online peer assessment.
