Space Based Repetition

Hi everyone - strange request, but has anyone implemented a “space based repetition” algorithm in Pharo/Smalltalk? Before going and implementing it for a little flashcard program for my daughter, I thought it might be worth checking as while it will be fun to implement I fear I may end up getting distracted on the wrong thing…

Actually - realised that Github search is better than I realised and found: https://github.com/olekscode/Flashcards

This has been on my TODO for ages and I'd be happy to collaborate. I am
especially interested in SM-2. I'll check out the repo you mentioned. I had
also started something basic, but IIRC didn't get far into the algorithm
yet...

Hi Sean - this implementation is Leitner, which would be ok for my needs, although I don’t quite know how you choose or specify the probabilities that are needed for this particularly implementation (and Leitner descriptions don’t mention this, but I can see the intent is to give you a random flashcard favouring new or unlearned cards and occasionally giving a learned card - but I’m not quite sure how you decide what to specify for that… I’m enquiring.

SM-2 always intrigued me… and would be cool to plug that in and compare - but was trying to avoid the inevitable rabbit hole and not get the actual task done (Which it sounds like you thought too…)

Please report back on your findings!

Yes, same. Although I'm sure I will eventually get pulled in lol. The
beautiful thing about flashcards in a dynamic system like Smalltalk is that
one could define an API so that *any* domain object could be turned into a
flashcard, like the birthdays of your contacts (silly example but you get
the idea). I did extensive reading on the SM-2 creator's website and played
with Anki a bit. It's been on my endless TODOs to do something simple like
Anki in Pharo...
