Peer learning is a strategy designed to enable learners to become active learners. Previous research reveals that college students need support to learn the tasks of their roles in enhancing peer learning. The model of peer learning presented in this paper incorporates scaffolding strategies to design structured peer learning activities in a higher education setting. This model was developed based on the sociocultural theory of zone of proximal development, foundational concepts of scaffolding, as well as three dimensions for operationalizing scaffolding. It includes four steps: (a) knowing each other, (b) learning together, (c) checking what you learned, and (d) finalizing the peer learning. This model can assist peers in choosing the appropriate scaffolding tactics for peer learning. Moreover, guidelines in the model are beneficial for instructors who wish to enhance their skills in designing peer learning activities and training peers.
