the goal of this master thesis is to get answers from national and international researchers and practitioners in digital teachning & learning (online learning, blended learning, etc.) about their experiences from the turbo-digitalization we all experienced during the last months. the thesis should collect a »state of the art« overview over a to-be-defined area of learning technology & didactics from before the pandemic (easy, since most publications are from that time) and then contrast it with recent statements from key researchers and practitioners that already reflect their experiences and research from the last couple of month. no programming required.
