Productively engaging in SRL is challenging for learners since it involves coordinating multiple motivational, affective, cognitive, and metacognitive processes. Researchers have investigated methods to adaptively scaffold learners' productive engagement using SRL processes automatically captured by SRL detectors. However, most previous studies relied solely on the frequency of SRL processes to drive adaptive scaffolds (e.g., feedback, hints), possibly missing the sequential characteristics inherent to self-regulation, a crucial dimension of productive SRL. To address this gap, this study analysed the impact of sequential transitions between multiple SRL processes on learners' performance on a reading-writing task with a hypermedia environment called Flora. A sample of 66 secondary-school learners completed the task and trace data were collected. Grounded in the COPES model of SRL, a rule-based SRL detector was employed to capture SRL processes from collected trace data. We employed a method combining logistic regression with ordered network analysis (ONA) to analyse the transitions between the detected SRL processes. This exploratory study revealed several influential transitions to learners' performance in different temporal learning blocks of self-regulation. The implications suggest the potential of using COPES SRL process transitions to drive adaptive scaffolds to facilitate engagement in productive SRL, benefiting performance outcomes in hypermedia environments.
