How to improve your memory with active recall

According to Supermemo.com, active recall means that your brain must generate the answer. You cannot just passively process information. It is not enough to read that "George Washington was the first US president." You need a question! For example: "Who was the first US president?"

In active recall, you would have to retrieve this information from your memory: "In which year of marriage are couples most likely to divorce?" If you answer correctly, "4th year," then your memory stability will increase and so will the probability of recall in the future. In passive review, this increase is dramatically less pronounced.
