Prof. Dr. Walther Zimmerli is a DSI Fellow since the Spring Semester 2020. He works on a philosophical-theoretical project RD2VH within the framework of DSI. The project is directed towards differentiating issues of digitalization historically and epistemologically from a critically reconstructed concept of digitalization into its dimensions in cognitive science, education and institutional theory. The aim is to develop a theoretical model of virtual universities of the second order. The focus is more precisely on the area of continuing education.
