Retrieval Practice Sprint

Retrieval practice, also called the testing effect, is one of the most-replicated findings in cognitive psychology. Roediger & Karpicke (2006) showed that students who were tested on material consistently outperformed students who simply re-read it, even on delayed tests. Active retrieval strengthens memory far more than passive review.

Agarwal & Bain (Powerful Teaching, 2019) translated this research into classroom-ready practice: brief, low-stakes retrieval — “quick-fire recall at the start or end of class” — consistently improves long-term retention and transfer. It also builds metacognition: kids learn to tell the difference between “I feel like I know this” and “I actually know this.”

The self-rating (Knew it / Sort of / Didn’t know) is deliberate: Karpicke & Roediger (2008) found that student confidence is a poor predictor of actual retention, but the act of rating forces a reality check that improves judgments of learning. Spaced retrieval over days or weeks outperforms massed practice — so for best results, sprint the same deck tomorrow, next week, and a month from now.
