This paper addresses questions of contextual learning experience sharing among users in personal learning environments. As learning environments has become personal and user oriented, a user can acquire knowledge and learning experiences anywhere and anytime by reading public or personal online learning resources aggregated by a set of provided tools. In this paper, we propose a system allowing a user to share his contextual learning experiences with his/her friends by sharing his contextual learning histories. This experience is propagated to others by using a trusted social network. Our system not only helps users to spread their learning experiences but also ensures user privacy (individual knowledge and preferences). It can be applied to enhance lifelong learning
