We
showed previously 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 to the learning
check testing in terms of the item response theory, where we used
the same testing results in prediction and in construction of the
mathematical model. However, such a treatment may cause the 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 to the learning check testing
and the past final examination results.
In prediction, we applied the nearest neighbor method for determining the similarity
in the trends of estimated abilities to the learning check testing. |
