Visualizing the Structure of Learning

Learning analytics means gathering a broad range of data, bringing the various sources together, and analyzing them. However, to draw educational insights from the results of the analyses, these results must be visualized and presented to the educators and learners. This task is often accomplished by using dashboards equipped with conventional and often simple visualizations such as bar charts or traffic lights. In this paper we want to introduce a method for utilizing the strengths of directed graphs, namely Hasse diagrams, and a competence-oriented approach of structuring knowledge and learning domains. After a brief theoretical introduction, this paper highlights and discusses potential advantages and gives an outlook to recent challenges for research.
