Subclaims¶

q3 i3 WTS course time-on-task correlates with perceived course difficulty at r=0.86, and variability measures such as WTS Time-on-Task Range (r=0.81) and LMS Time-on-Task SD (r=0.75) are key indicators of perceived difficulty. → Paul V. Sargent 2026 q3 i3 Positive weekly slopes correlate with perceived difficulty (r=0.45), with negative slopes showing milder correlations (r=0.23). → Paul V. Sargent 2026 (2)

q3 · i3 · associational · r1

Course-level Spearman correlation analysis of workload features against perceived difficulty across 14 engineering courses. WTS course time-on-task correlated at "r=0.86" and LMS Course Average Sessions at r=0.82 with perceived difficulty.

"Notably, measures of variability showed strong correlations with Perceived Difficulty, primarily regarding WTS Time-on-Task Range (r=0.81 ), LMS Time-on-Task SD (r=0.75 ), and WTS Time-on-Task SD (r=0.73 ). These relationships indicate that variability measures—from both LMS and WTS data—are key indicators of perceived course difficulty."

q3 · i3 · associational · r1

Week-level correlation analysis of weekly workload slopes against perceived difficulty. Positive slopes correlated at "r=0.45"; negative slopes correlated more mildly at r=0.23 (WTS) and r=0.17 (LMS).

"Slope measures were also related to higher levels of perceived difficulty, most notably in the case of the WTS Time-on-Task positive slope ( r=0.45 ). Interestingly, negative slopes were also related to higher perceived difficulty, albeit with milder correlation coefficients (WTS:r=0.23 , p<0.001 ; LMS: r=0.17 , p<0.01 )."

Related Claims¶

• Courses with higher average time-on-task exhibit greater variability in their weekly workload evolution — related
• Quizzes are the only LMS activity type negatively correlated with reported time-on-task and perceived difficulty — related
• Self-reported weekly time-on-task is positively correlated with LMS-based time-on-task and activity measures in engineering courses — related
• Workload peaks and slope variability correlate with perceived learning attainment, with LMS dynamics showing no significant correlations — related
• Invested mental effort and perceived task difficulty are strongly correlated yet relate differently to relative task difficulty, indicating the two ratings measure different aspects of overall cognitive load — related
