A colleague of mine has been working for some time on an adaptive learning system for mathematics. It does work, but we are not sure it will ever reache production quality, so I wonder if somebody has already done something similar in Moodle.
I did see the adaptive quiz plugin, but that focuses on assessment, and appears to assume that the student's skill level is constant during the quiz. Other search results also seem to focus on assessment.
For us, the adaptive questions make a learning activity only. The idea is to drill the student by flooding him with questions at the right level of difficulty. My colleagues system is gamified by issuing starts (up to five), depending on the ratio of correct answers over a certain number of questions, but anything which gives the student a clue of his performance is good.
I guess the key property we are after is an infinite sequence of questions in the quiz. Questions are parameterised by random numbers. I think Moodle has an appropriate question type, so the question is really to get a quiz of an infinite number of questions ...
Has anyone seen anything similar?
