Spaced Repetition is a memorization technique where you use active recall at specific intervals to learn new concepts.
A German researcher, Hermann Ebbinghaus, discovered that in 30 days from learning a new concept, 90% of the information is lost. Retrieving that information at different periods of intervals (e.g., one day, three days, seven days) is reducing this percentage to less than 20%.
Spaced Repetition is superior to the classical approach for learning, also known as cramming or massed learning, because it fosters the re-consolidation of memory, strengthening the connections to previous knowledge.
What is the right repetition interval? The interval between session depends on the type of material that is being learned. For example, names and faces, need repeating in a matter of minutes, others, like facts or classic subjects, require a matter of hours.
Independent of the type of the material, or the feeling of mastering the subject, the interval should not be bigger than one month.
How to use it? The most simple way to implement this method is through flashcards. However, there are also digital solutions like Anki, that allows you to work with digital flash cards that are always available to you.
My favorite schedule is a 30-min session in the morning and another one in the evening, repeated at least 3 times per week. (You can increase to 7 times per week, depending on the volume of new information or the time you have available)
