Our research has contributed to measures and mechanisms of social processes in digital learning environments, using digital learner traces, in MOOCs. We contributed interaction-based indicators of whether MOOC learners are forming a community based on relationships. Through this work we put forward a multi-level conceptualization of MOOC participation, which enables to measure learner relationships arising from interactions. We have also provided evidence that MOOCs are identity-based communities, not bond-based communities. This is a valuable contribution since most digital learning pedagogy, as well as instruments to measure processes in digital learning settings, are designed for bond-based communities common in university courses. Indicators of MOOC as identity-based communities have been replicated on another dataset. These have been published in The International Review of Research of Open and Distance Learning (2018; IF 0.7), Computers and Education (2020; IF 5.3), Learning Analytics and Knowledge Conference (2016), among others. Various empirical and review studies on the subject are listed below.
