Cognitive load and knowledge sharing in Learning Networks.
Learning Networks (LNs) are online social networks designed to support\nnonformal learning; they are therefore particularly suitable for self-directed\nlearners. In LNs, learners need to construct knowledge through knowledge\nsharing with other participants. However, without support, learners have to\norganize knowledge sharing themselves and this could induce extraneous\ncognitive load. When working on complex learning tasks, this organizing process\ncould have a detrimental eﬀect on knowledge construction. To optimize cognitive\nload, we propose using a peer support system that applies the mechanisms of peer\ntutoring to support knowledge sharing. Its mechanisms reduce, we argue, the\nextraneous load imposed by having to organize knowledge sharing as well as\ninduce germane load by directing the freed-up cognitive capacity to processes that\ncontribute to knowledge construction.
