The seminar defines as Open Science practices and processes in all scientific disciplines that foster participation and collaboration, accessibility and reuse, transparency and verifiability in science. This is linked to the use and promotion of an open web and the provision of infrastructures for scholarly research, teaching and learning. Open Science also promotes sustainable impact, both transdisciplinary in the science system as well as in politics, business, culture, and public life. Open Science is rooted in the tradition of established principles of good scientific practice. The goal is to critically reflect traditional scientific culture and to transfer it into the present era of linked-up research. Based upon experiences made in the EduArc project, the talk will place the emphasis on open educational resources and challenges to fully integrate them into teaching practices at universities.
