“…However, due to the anonymization of the data, we could not investigate the role of individual di erences with respect to learner characteristics, as no participant-specific information was available. Therefore, future research may expand on our study by considering individual learner characteristics such as motivation, personality, cognitive abilities, prior academic achievement, socioeconomic status, or math anxiety (e.g., Bardach et al, 2023;Meyer et al, 2023) and their e ects on learning trajectories within ITSs (Hilz, Guill, Rolo , Aldrup, & Köller, 2023;Hilz, Guill, Rolo , Sommerho , & Aldrup, 2023). In addition, it would be illuminating to combine the process learning data used in our study with students' self-reported learning behavior and emotional dynamics during learning, as well as other behavioral assessments (e.g., emotion recognition systems, eye-tracking, heart rate variability, EEG data) to dig even deeper into the details of mathematics learning with ITSs.…”
