Live annotation and content discovery in personal learning environments

Personal Learning Environments (PLEs) are gradually gaining ground over traditional Learning Management Systems (LMS) by facilitating the lone or collaborative study of user-chosen blends of content and courses from heterogeneous sources, including Open Educational Resources (OER). Our work is focused on the social aspect of PLEs, and particularly on live interactions between learners, real-time annotation of OER and content discovery. This paper describes Gravpad, a service for sharing live annotations, and showcases how it can contribute to social learning within a PLE.
