q2 i? For 100 Open University learners with day-grained page-click time-series, a robust 3-way partition separates massed from distributed learners, with 6/7 low performers in the massed cluster and a significantly lower grade (paired t-test at 5%) than the distributed cluster. → Peach 2019

q2 · i? · associational · r1

Test of the pipeline on the OULAD dataset (100 learners, day-coarse-grained page clicks rather than task completion). "6/7 of the low-performance learners (<60%) were located in the cluster associated with massed learning"; the partition was robust across sparsification levels.

"We found that 6/7 of the low-performance learners (<60%) were located in the cluster associated with massed learning, while one low-performance learner was located in the minor outlier cluster and none were in the distributed learning group."
