How Spaced Repetition Can Make You Learn 5x Faster (or more) Than Those Who Don’t Apply Spaced Repetition
Learning as a compounding investment
I have always been aware that spaced repetition is very effective, but I always wondered “To what extent”?
Today, however, I made the random / associative connection between learning speed and Ebbinghaus’ forgetting curve (seen in the picture).
As far as I am aware, the linkage is as follows:
“The further in time, the faster your learning speed is in comparison to those who don’t apply spaced repetition.”
If, for example, a month has passed, those who don’t apply spaced repetition have retained only 21% while those who have applied spaced repetition have retained approximately 95%.
This means that, after a month has passed, spaced repetition can make you learn 5x faster than those who don’t!
(I’m not a mathematician or logician, so correct me if I am wrong).
So, every hour where you do effectively apply spaced repetition, that requires 5 hours for those who don’t! (After a month has passed)
What do you think about this?
