What are flashcards?
A flashcard is a small paper card that holds a word on one side, its meaning on the other. You glance at the front, try to recall the back, then check yourself by flipping it around. Nothing could be simpler, yet few tools rival flashcards for cementing vocabulary. Digital flashcards are much more convenient store and let you review anywhere, anytime.
What is the Spaced Repetition Method?
Spaced repetition is a technique for learning flashcards that schedules your next card reviews by the card’s difficulty. This way you don’t review all of your cards every day, but just the ones that you don’t yet know well. Unfamiliar or shaky words will resurface more frequently in time, while known words fade into ever-longer intervals. It’s among the most efficient memory techniques known. This Wikipedia article outlines the psychology behind it.
