Translations:Techniques that maximise learning/23/en
There are a number of theories concerning forgetting. Most important for our purpose as instructors is that over 60% of factual information will be lost within 48 hours if there is no subsequent rehearsal or review of what was learned. Skills and understanding are much more resistant to forgetting. For example, once you learn to swim, it is unlikely that you will ever forget how to swim, even if you do not swim for many years.
