In SRS design, Anki and Quantum Country ask you to think of the answer; Duolingo and Execute Program ask you to input an answer.
I’d thought: latter’s likely more effective, but annoying & slow. Surprised to see these studies found little diff in recall: andymatuschak.org/files/papers/L

(See chapter 6, which describes the three experiments. Some limitations: targets were Swahili–English word associations; performed on smallish sample of undergrads; maximum retrieval interval of a week. This thesis is intensely interesting throughout!)

One fun oddball: at least as of Dec ’17, Quizlet presents a multiple-choice input the first time, then transitions to text input / self-graded afterwards. The theory is that recognition is easier than recall, so maybe makes sense to “bootstrap” that way.

I wonder how this turned out! The cogsci as I understand it could go either way:
+: performance on initial trial strongly affects subsequent forgetting
–: "desirable difficulty”; recall promotes slower forgetting than recognition

Have you heard of Brainscape? It's like Quizlet, but it's all self-graded instead of machine-graded.
(For math teachers, it's way better because you can put images on both sides of the flashcard, e.g., an image of a formatted equation on one side and a graph on the other).

Yep! Do you use it in your classes? If so, I’d be curious to hear about how you integrate it into your lesson plans.

I wanted to use it, but unfortunately their privacy settings make it impossible for a K12 setting (people can search for users and read their bio's).
Flashcard systems like this are a really simple differentiated activity...kids add cards to the deck depending on mastery.

They're ideal for picking up odds and ends of time. 6 min is plenty to work through a few cards. I find published curricula struggle to keep the big threads of a course in view at all times. Published practice Q's ask kids to solve a whole question at once & give the answer.
