How often should information be reviewed to avoid forgetting?

Regular and frequent review of information is essential for effective learning and memory retention. This approach leverages the spacing effect, a cognitive phenomenon where information is more easily recalled if it is studied in intervals rather than crammed in a single session. By reviewing material regularly, students reinforce their understanding and create stronger neural connections, making it easier to access that information later.

The idea is that as time passes, without review, the likelihood of forgetting increases. By engaging with the material consistently, learners can better commit information to long-term memory, thus reducing the chances of forgetting crucial concepts. This practice also helps recognize gaps in knowledge that can be addressed before assessments or practical applications. Therefore, regular and frequent review is the most effective strategy to ensure information is retained over the long term.
