“…Based on criteria for high-quality MOOCs (Egloffstein, Koegler, & Ifenthaler, 2019;Margaryan, Bianco, & Littlejohn, 2015), we developed, evaluated, and refined the initial version. For a detailed description of the design research process of developing and improving the i-MOOC, see Seufert, Guggemos, Moser, & Sonderegger (2019) and Moser, Guggemos, & Seufert (2021). Supplementary material S2 outlines how the design criteria for high-quality MOOCs are considered in the i-MOOC.…”
