Limits to accuracy: how well can we do at student modeling?

  title={Limits to accuracy: how well can we do at student modeling?},
  author={Joseph E. Beck and Xiaolu Xiong},
There has been a large body of work in the field of EDM involving predicting whether the student’s next attempt will be correct. Many promising ideas have resulted in negligible gains in accuracy, with differences in the thousandths place on RMSE or R. This paper explores how well we can expect student modeling approaches to perform at this task. We attempt to place an upper limit on model accuracy by performing a series of cheating experiments. We investigate how well a student model can… CONTINUE READING
