What is retrieval practice and how can I use it in the classroom?

Memory is strengthened by retrieval practice. What does it mean? According to psychologists such as Robert and Elizabeth Bjork and Yana Weinstein (one of the Learning Scientists), our capacity to remember things in the long-term is strengthened by practising the process of retrieving information from our long-term memory into our working memory. The more we practise remembering, the easier it is to do and the longer we can recall the information for. The less we do it, the more we forget. The effect of retrieval practice is stronger than re-reading or being told the same information repeatedly. (You can read more about cognitive load and working memory here.) There are many forms of retrieval practice, depending on the material in hand. It can simply be mental rehearsal of factual knowledge, mental elaboration (where you explore connections between ideas) or practical drills and rehearsals that make the retrieval process more automatic.
