Self-regulated learning has seen a large increase in research interest due to its importance for online learning of higher education students. Several ways to measure self-regulated learning have been suggested. However, most measurements are either obtrusive, necessitating time and effort from students and potentially influencing the learning process, or only partially portable across courses. In the current study, we develop clickstream-based scales of four self-regulated learning phases that we show are portable across courses. The final scales are based on the COPES model and include two strong and reliable dimensions, enactment and adaptation, one dimension that performs reasonably, task definition, and a weaker one, goal-setting. By considering portability as the main criterion in the scale construction process, we ensured reliable transfer to both similar and dissimilar courses. When considering convergent validity, the created scale has higher bivariate and partial correlations with final student grades than the often-used self-reported MSLQ-SRL scale. We discuss limitations and future research to improve the scale further and facilitate adoption.
