[ARCHIVED] Adaptive quizzes?

[siouxgeonz]

    On www.mathisfun.com there's a set of pages for "training" including this one for addition: Math Trainer - Addition   .   It's programmed so that if a person misses a fact, then it displays the right answer, and the timer (if it was being used) stops until the right answer is entered... then another question and then the 'missed one' appears again. 

    I don't know how sophisticated the "get more practice on the ones you missed" programming is, but before I mess around with it I was wondering if anybody knew of an example of that out there already.   (I was going to try to do it in Java since that's what I'm most familiar with... then try to translate that into JavaScript so that it could -- I think? -- get included in a quiz on Canvas?)

I'm not sure how technical the "get more practise on the ones you missed" programming is, but before I fiddle with it, I was wondering if anyone knew of a working example of it. ( Because to my familiarity with Java, I was going to attempt to implement it.
