Extensive research has taken place on how the brain learns new information. It is widely believed that we acquire knowledge into our working memory from the environment. However, whilst the environment is an unlimited source of information, the capacity of our working memory is more limited; only allowing us to juggle so much in our minds at any one time. Linking this new information to prior knowledge helps us move it into our long-term memory, which as far as researchers are aware has no limit. Once it is there, we need to regularly recall this information so that we don’t lose our ability to retrieve it when needed. Whilst research into this field is ongoing, this fundamental idea is allowing us to continue to develop strategies to help our students with a deeper understanding of topics and the ability to recall this information when required.
