Ebbinghaus's experiment revealed the secret of human memory. The more you remember, the faster you may forget without adequate review. In fact, Ebbinghaus's forgetting curve theory mainly says that after one hour, on average, only 44.2% of what has just been stored in the brain will not be forgotten, and when the time passes two days, the proportion will drop from 44.2% to 27.8%. After many days, people at that time may not remember much. This theory mainly expounds the importance of review, and holds that each of us will have the same feeling in life, that is, what we review often can be remembered more firmly.
From the chart, Ebbinghaus forgetting curve can be divided into two stages. The first stage is its rapid decline stage; The second stage is its gradual progress. The first stage tells us that in the initial time, if we don't review what we have learned, our memory will be greatly damaged. The second stage tells us that after each review and consolidation, the speed of forgetting will be much lower than the last one until a long-term memory is formed.
Therefore, Ebbinghaus's forgetting curve advocates counteracting "forgetting" through review. As long as you repeat it more times, you will remember it better. This is why every middle school classroom will post an Ebbinghaus forgetting curve, which is to warn students to digest, consolidate and remember what they have learned through repeated learning, so that they can easily recall accurate knowledge in the examination room.
