摘要：Knowledge sharing occurs betw een humans, rather than being a human-computer process. Knowledgetransformation is an outcome of individuals' knowledge-sharing experiences. Social interac tion is central to both knowledge transformation and to learning. When learners intermingle, there may be a shift in knowledge due to the social interaction. Consequently, knowledge transformation is a social process that occurs when there is an interaction among learners. In a contact university, learners perform task s in three locations: formal contexts, semi-formal contexts and informal contexts . Learning tasks arepresumed to be constant but a mobile learner carries the tasks across different environments. However, as learners move across different contexts , they do not have access to the same social networks for sharing knowledge and learning experiences. The paper conceptualises a mobile learning environment that provides social presence awareness as a learner traverses different learning contexts. It highlights how through synchronous mobile instant messaging, social presence provides learners with continuous awareness of available social support, thus facilitating the on-demand and opportunistic sharing of knowledge
