Data literacy is considered a key competence for responsible, mature citizens of the 21st century. In this poster the interrelatedness of information literacy and data literacy is addressed. It then elaborates on how universities can make their students fit in dealing with data and information using the example of a new research project about the development of open educational resources to promote data literacy at Swiss universities. Thirteen universities work together in a unique cooperation to promote the key competence data literacy among university teachers and students. The project aims to ensure responsible, critical, ethical and sustainable handling of data during university education and builds upon existing initiatives to promote data literacy (e. g., by the Stifterverband in Germany).
