âRetrieval practiceâ is a learning strategy where we focus on getting information out. Through the act of retrieval, or calling information to mind, our memory for that information is strengthened and forgetting is less likely to occur. Retrieval practice is a powerful tool for improving learning without more technology, money, or class time. On this website (and in our free Retrieval Practice Guide), we discuss how to use retrieval practice to improve learning.
