Hermann Ebbinghaus
• made up lists of nonsense syllables and measured how long it took to forget and then relearn them.
• (Example of the type of list he used: besdek fel gup huf jeik mek meun pon dausdor gim ke4k be4p bCn hes.)
• Forgetting curve
• The Spacing Effect

The Forgetting Curve

The Spacing Effect
“Ebbinghaus showed that it's possible to dramatically improve learning by correctly spacing practice sessions. On one level, this finding is trivial; all students have been warned not to cram. But the efficiencies created by precise spacing are so large, and the improvement in performance so predictable, that from nearly the moment Ebbinghausdescribed the spacing effect, psychologists have been urging educators to use it to accelerate human progress. After all, there is a tremendous amount of material we might want to know. Time is short.”

Piotr Wozniak - The Algorithmic Man

When to practice?
“SuperMemo is based on the insight that there is an ideal moment to practice what you've learned. Practice too soon and you waste your time. Practice too late and you've forgotten the material and have to relearn it. The right time to practice is just at the moment you're about to forget.
Unfortunately, this moment is different for every person and each bit of information. Imagine a pile of thousands of flash cards. Somewhere in this pile are the ones you should be practicing right now. Which are they?”
