Lehrstuhl Informatik 5 (Information Systems) Prof. Dr. M. Jarke 2 Learning Layers Abstract Learning Analytics has become a major research area recently. In particular learning institutions seek ways to collect, manage, analyze and exploit data from learners and instructors for the facilitation of formal learning processes. However, in the world of informal learning at the workplace, knowledge gained from formal learning analytics is only applicable on a commodity level. Since professional communities need learning support beyond this level, we need a deep understanding of interactions between learners and other entities in community- regulated learning processes - a conceptual extension of self- regulated learning processes. In this presentation, we discuss scaling challenges for community learning analytics and give both conceptual and technical solutions. We report experiences from ongoing research in this area, in particular from the two EU integrating project ROLE (Responsive Open Learning Environments) and Learning Layers (Scaling up Technologies for Informal Learning in SME Clusters).

Jarke 19 Learning Layers Communities of Practice Communities of practice (CoP) are groups of people who share a concern or a passion for something they do and who interact regularly to learn how to do it better (Wenger, 1998) Characterization of experts in CoP – Shared competence in the domain – Shared practice over time by interactions – Expertise based on gaining and having reputation within the CoP – Being an expert vs. being a layman, a newcomer, an amateur etc. – Informal leadership – Identity as an expert depends on the lifecycle of the communities Expertise in highly dynamic, locally distributed multi-disciplinary and heterogeneous communities?
