Studying a list of words, then retrieving them. And, doing that over and over causes the information to be stored in long-term memory, to be retrieved when they need it. The American Psychological Association cites that recent research has established that repeated retrieval enhances learning with a wide range of materials, in a variety of settings and contexts, and with learners ranging from preschool ages into later adulthood. 

Students practiced retrieval practice with a science passage where they read the passage and wrote down everything they remembered. They then repeated this practice again. The second set of students read the passage and made concept maps of the information. When tested, the retrieval practice was almost twice as likely to provide meaningful learning. Retrieval practice can work for any subject which requires reading.
