The testing effect—a phenomenon which suggests that testing enhances later retention—was investigated through a study called “Test-Enhanced Learning: Taking Memory Tests Improves Long-Term Retention”. Previous studies analyzing the testing effect fail to do so in an educational context. Roediger and Karpicke set out to discover this gap in the literature and prove whether or not testing promotes the learning process beyond restudying. To analyze their hypothesis, the researchers conducted two separate experiments. Their findings proved that, within educational contexts, testing is a crucial element on both the learning and long-term retention of educational materials than simply the re-studying of these materials.
