This dataset was collected as part of a design-based research (DBR) study investigating the development of students’ time management competencies through iterative experiential learning interventions. The data span three implementation cycles and include daily behavioral records, classroom observation notes, and student self-reports. Core variables include the number of valid recording days, total planned and completed tasks, task category diversity, planned completion rate (based on a 5-point scale), average daily time allocation (academic and non-academic), and daily self-assessment scores. Data were collected through structured templates (iteration 1), Sojump online forms (iteration 2), and a WeChat mini program (iteration 3). Identifying information has been removed to ensure participant anonymity.Due to privacy considerations and data volume, only partial, thematically relevant interview and course record data are disclosed here.
