Space learning over time with review and quizzing.

A key aspect of effective teaching and learning is helping students retain information over the course of the school year and beyond. Research has shown that exposing students to key concepts and facts on at least two occasions, separated by several weeks to several months, greatly reduces the rate at which information is forgotten. This is accomplished by re-exposing students to course material after its introduction and by reviewing material with short quizzes, review games, targeted homework assignments, and exams.
