q2 i? The Crammers cluster shows the lowest mean task completion (66%) and a higher mean massed session length than other clusters, with completion rising through Low Engagers (80%), On time (86%) and Early Birds (90%). → Peach 2019

Time-series metrics computed per learner and mapped onto the similarity graph (Fig. 4): mean massed session length via isotonic regression and percentage of tasks completed. "the 'Crammers' cluster shows the lowest mean task completion (66%)" with the ordered completion ratios above.

"the 'Crammers' cluster shows the lowest mean task completion (66%), followed by a completion ratio of 80% in the 'Low Engagers' group, and a higher mean task completion rates in the 'On time' (86%) and 'Early Birds' (90%) clusters."

• Low-performing learners concentrate in the massed-learning ('Crammers') cluster, with 6 of 7 low performers in that cluster in the main cohort — related
• The methodology replicates on a second cohort of 46 learners, with only 1 of 8 low performers in the distributed-learning cluster — related
