Spaced Repetition

Ever wonder what the most efficient way to learn something is?
This fascinating piece argues that the best approach for long term memory retention and learning is spaced active repetition.
The idea is to actively (i.e. asking a question) recall information at ever increasing intervals, using software to help timing.
As the chart below shows – cramming (massed repetition) works well in the short run but for the long run spaced repetition wins.
