Thanks - I still haven't used it for mathematics, but this is good to know. I do have a few proofs of theorems in statistics in my flashcards, but the whole point of the cards is to spend only a few minutes a day on them - and doing a few proofs requires a paper, pen, and time. So I keep those in a separate deck and do them only when I know I have time.
My concern with mere cloze deletion is that I'll likely get the illusion of understanding without real testing (being able to rederive something is a real test). I'll likely go for a hybrid approach - full proofs in a separate deck and either proof sketches or cloze deletion in the regular deck.
> One of the most important things I remember mentioned in that class was that memorization and understanding are actually quite tightly linked.
This stood out to me when I took the course, although my memory of it is different. I don't think she said memorization, but "covering it and reproducing it in your own words" - the latter requiring understanding. But yes, she claimed that the research showed this outperforms things like mind maps, and that nothing has so far been shown to outperform this.
