Query: A New Item Response Theory Model for Open-Ended Online Homework with
  Multiple Allowed Attempts   Item Response Theory (IRT) was originally developed in traditional exam
settings, and it has been shown that the model does not readily transfer to
formative assessment in the form of online homework. We investigate if this is
mostly due to learner traits that do not become apparent in exam settings,
namely random guessing due to lack of diligence or dedication, and copying work
from other students or resources. Both of these traits mask the true ability of
the learner, which is the only trait considered in most mainstream
unidimensional IRT models. We find that indeed the introduction of these traits
allows to better assess the true ability of the learners, as well as to better
gauge the quality of assessment items. Correspondence of the model traits to
self-reported behavior is investigated and confirmed. We find that of these two
traits, copying answers has a larger influence on initial homework attempts
than random guessing.
