Open Education in Higher Education is addressed by a wide variety of actors, e.g. librarians, teaching and learning consultant, decision makers, scholars, students. Furthermore, Open Education, through the deeper transformations it brings with it concerns the wider society. Nevertheless, scholars of education sciences engaged on the topic are very few. The aim of this workshop is to discuss the design of a research project to advance our understanding of Open Education from the multidisciplinary perspective of education sciences. To gain insights, the idea is to start with SoTL approaches to then transition towards epistemic levels. At the same time, the idea is to provide some literature review on key concepts and their variety of understandings, e.g. Openness, Freedom, Right, Diversity of knowledge systems, to equip scholars and students and enable them to understand OE in its width and depth.
