RT Conference Proceedings T1 Key Action Extraction for Learning Analytics A1 Scheffel, Maren A1 Niemann, Katja A1 Leony Arreaga, Derick Antonio A1 Pardo Sánchez, Abelardo A1 Schmitz, Hans-Christian A1 Wolpers, Martin A1 Delgado Kloos, Carlos AB Analogous to keywords describing the important and relevant content of a document we extract key actions from learners' usage data assuming that they represent important and relevant parts of their learning behaviour. These key actions enable the teachers to better understand the dynamics in their classes and the problems that occur while learning. Based on these insights, teachers can intervene directly as well as improve the quality of their learning material and learning design. We test our approach on usage data collected in a large introductory C programming course at a university and discuss the results based on the feedback of the teachers.
