Studying the laws of memorization, the German experimental psychologist German Ebbinghaus statistically proved that if a person does not repeat the material studied, then the storage of material in memory decreases almost exponentially with respect to time. He called these arcs the “Curve of Forgetting”. In this case, the information is forgotten at first very quickly, and then slower.

More than two centuries, research has been conducted on the functional abilities of the human brain. Nowadays, natural and artificial intelligence are being compared by researchers.

Our method on the “Ebbinghaus Forgetting Curve” is based on using Control Charts with exponentially weighted moving average memory (EWMA chart for the mean values).

The control value of this chart has a normal distribution. Using this, we find the upper and lower control lines of this chart. The central line (target value) we determine at the request of the educational process.

If we find the hypothesis to battle the forgetting curve, we conduct experiments to test the hypothesis. Using the samples obtained from the experiment, we calculate the values of the control values. Laying these values between the control lines relative to the target value means to battle the forgetting curve. We showed that how the EWMA card of average values works to solve the task in specific situations of the educational process.
