ABSTRACT
In the 21st century learning increasingly happens on the social web. Learning has evolved into an interactive social process producing large amounts of data across a multitude of inhomogeneous systems. To identify the role of individual actors and groups of actors the whole global learning network needs to be analyzed. The work presented in this paper ingests learning data into a cloud hosted distributed temporal graph model with a supporting distributed processing framework to calculate global graph metrics. The presented simple architectural approach builds upon the xAPI specification to ensure compatibility and flexibility. Based on the global graph metrics we can detect communities and identify information brokers. This information enhances the understanding of the learner's personal learning network and its development over time. It contributes to ongoing efforts to guide learners' through the tangled undergrowth of the global social learning network towards individuals and communities relevant to their interests, skills and aptitudes.

Social learning analytics: five approaches
LAK '12: Proceedings of the 2nd International Conference on Learning Analytics and KnowledgeThis paper proposes that Social Learning Analytics (SLA) can be usefully thought of as a subset of learning analytics approaches. SLA focuses on how learners build knowledge together in their cultural and social settings. In the context of online social ...
Learning Analytics as a Metacognitive Tool
CSEDU 2014: Proceedings of the 6th International Conference on Computer Supported Education - Volume 1The use of learning analytics is entering in the field of research in education as a promising way to support learning. However, in many cases data are not transparent for the learner. In this regard, Educational institutions shouldnâ t escape the need ...
