Kot is a basic toolkit for getting started with computerised adaptive testing (CAT) in Ruby.
It includes:
- a module to calculate item response theory (IRT) statistics for dichotomous items with 1-4PL characteristic curves (ICCs),
- a Hill Climbing ability (theta) estimator,
- a Randomesque selector and
- a Test class to make tying all this together easier.
douglasrizzo'scatsim and its excellent documentation,without which I wouldn't have been able to cobble this together.
