Does Duolingo Work?
- charlesism 8y agoDuolingo’s design largely relies upon a system called “spaced repetition,” a technique in which learned information is repeated at regular (usually short) intervals Aside from the author's other criticisms, she just takes it on faith that Duolingo actually implements a proper SRS. I'm not sure they do. The other apps and webapps I have used seems seem to have much better Spaced Repetition algorithms.
