Test-Enhanced Learning: Taking Memory Tests Improves Long-Term Retention

Henry L. Roediger III, Jeffrey D. Karpicke · 2006 · Psychological Science 17(3), 249–255

Being tested on material beats re-reading it — dramatically — once you look a week out instead of five minutes.

The short version
  • Students who read a passage once and were then tested on it remembered more a week later than students who read it twice.
  • The re-readers felt more confident and did better after five minutes; the advantage flipped by two days and widened by a week.
  • The test worked even without feedback — the act of retrieving is itself a learning event, not just a measurement.
  • Saasworld's mid-lesson gates and the daily drill exist because of this line of work.
