- The study is based on research on the rapid transition to online teaching during the COVID-19 pandemic (Emergency-Remote-Teaching, ERT, Hodges et al., 2020), the concept of Scholarship of Teaching and Learning (SoTL, Boyer, 1990; Huber, 2014), and its own predecessor study from 2020. The qualitative and comparative longitudinal analysis revealed a number of categories, including a fundamentally positive assessment of their own ERT experiences, but at the same time a differentiated picture of both their own teaching and involvement in SoTL. Furthermore, the interview analysis suggests that the teachers have gained important competencies for the situation of ERT through their SoTL projects, which could also prove useful outside of ERT.
