All over the world, education is undergoing substantial changes in the wake of rapid technological developments. As our world is becoming ever more digitized, the educational sector is increasingly infused with digital games, apps, websites, social media, and learning environments. The Covid-19 pandemic, and associated measures of social distancing and school closures all over the world, have accelerated this digitization, triggering an urgent need for critical, up-close scrutiny of how this digitization is reshaping the worlds of education. The focus of this Special Issue is especially on digital education platforms. Over the last years, such platforms have become progressively prevalent, and both global and local technology companies have become omnipresent providers of such platforms, in private as well as in in public education (Van Dijck et al., 2018). From platforms tailored to primary and secondary schools to platforms specifically constructed for the field of higher education; from digital environments designed to manage pupils' learning to environments focused on the monitoring of their behavior; and from digital spaces bundling a variety of functionalities to interfaces with a more singular function: no matter the focus, there seems to exist a corresponding digital platform used within (and often especially made for) the educational field (Hillman et al., 2020; Robertson, 2019; Williamson, 2019). Furthermore, the worldwide growth and ubiquity of digital education platforms has greatly accelerated since the outbreak of the Covid-19 pandemic and the associated newly emerging 'emergency pedagogies' that needed to be devised, often with help of both existing and newly developed digital education platforms (Williamson et al., 2020). In that sense, and in line with related scholarship on how education is taking-and changing-dedicated shapes, we advance the general thesis here that, under the influence of digital platforms, educational practices are gradually changing form (e.g., Decuypere & Vanden Broeck, 2020; Lewis, 2020b). Despite the steady rise and ubiquity of digital education platforms, however, educational research that adopts a critical gaze vis-à-vis such platforms is still surprisingly limited (
