Learning technologies offer opportunities for users to enhance and to personalize self-regulated learning activities. In this paper, we present the results of a laboratory study that covers the user evaluation of the AFEL Didactalia app, which analyzes everyday learning activities of
learners, extracts learning scopes and trajectories, and provides personalized recommendations of learning resources as well as an interactive visualization of learning activities. Participants of the study (N=76) engaged with the tool after first completing an assigned learning task related to geography or history using learning materials from the Didactalia platform for approximately 30
minutes and afterwards freely exploring the platform for 30-45 minutes. The related behavior
data was tracked and analyzed by the AFEL learning tool. After completing the two tasks, participants received an introduction to the tool and explored them as well. The results suggest a satisfactory experience with the tool and provide insights on the potential benefits, as well as
aspects to be improved for further development. We discuss our findings and the next steps of the investigation in detail
