| Previously,
we showed that we can predict the success/failure status for the
final examination to each student at early stages in courses using
the current trends of estimated abilities in terms of item response
theory for online testing. However, we used the same testing results
in prediction and in construction of the mathematical model, which
may cause overfitting effect. In this paper, we have shown that
we can still predict the current success/failure status for the
final examination using the past trends of estimated abilities
of the online testing and the past final examination results. |
