Using Peer Tutoring to Optimise Knowledge Sharing in Learning Networks: A Cognitive Load Perspective

Self-directed lifelong learners often intentionally look for non-formal learning opportunities. Learning Networks (LNs) provide them with an online social network to share knowledge with others. Lacking a formal social structure, the educational environment of non-formal LNs is different from formal learning settings. Thus, knowledge sharing becomes difficult because the learning environment of LNs could induce cognitive load, especially when learners deal with complex learning actions. A possible solution is to provide a structure to support interaction and thus reduce cognitive load. We propose peer tutoring as a support structure to assist learners to share knowledge.
