Recent studies have shown that retrieval (a process of accessing certain information in your brain) is critical for robust, durable, long-term learning. Every time a memory is retrieved, that memory becomes better available for access in the future. Not surprisingly, practicing memory retrieval produces more knowledge retention than other effective techniques. From these findings, we understand that the retrieval process has a central role in learning. What’s interesting is that the benefits of repeated retrieval are not isolated to a particular type of learning, and instead appear with a variety of mediums, learning settings and situations including eLearning, online simulations and blended learning programs. Here’s another great fact: retrieval improves learning for a variety of learners ranging from preschoolers to senior citizen.
