What happened
The Learning Scientists published a post by Carolina Kuepper-Tetzel preparing for a new course and revisiting a 2020 piece on spaced practice. The repost summarizes Carvalho, Sana, and Yan’s NPJ Science of Learning study, which analyzed platform data from 639 students in a 12-unit online course with readings, videos, activities, weekly quizzes, and a final exam. The study used the number of sessions needed to complete a unit as its spacing indicator.
Why it matters
According to the repost, more spacing was associated with higher quiz performance independent of total time on a unit and pretest performance. It also reports that more able students tended to space more, while spacing was more strongly associated with quiz performance for lower-ability students and for students completing fewer activities. For course teams, that points to pacing design as a practical support, especially in online learning where self-regulation is required.
What to do next
Audit courses for whether learners can distribute work across multiple sessions rather than finish units in one sitting. Add low-stakes reminders, checkpoints, or activity sequences that make spaced engagement visible. Treat the evidence as correlational platform analytics, not proof that any single schedule will improve outcomes, and monitor quiz, completion, and engagement data before scaling changes.
