Abstract—We present an approach and a system to let tutors
monitor several important aspects related to on line tests, such
as learner behavior and test quality. The approach includes the
logging of important data related to learner interaction with the
system during the execution of on line tests, and exploits data
visualization to highlight information useful to let tutors review
and improve the whole assessment process. We have focused on
the discovery of behavioral patterns of learners, and conceptual
relationships among test items. Furtermore, we have led several
experiments in our faculty in order to assess the whole approach.
In particular, by analyzing the data visualization charts we have
detected several previously unknown test strategies used by the
learners. Lastly, we have detected several correlations among
questions, which gave us useful feedbacks on the test quality.
