Data from a Web-based Homework Tutor can predict Student’s Final Exam Score
نویسنده
چکیده
We discuss new measures in assessing the skill level of students based on their interactions with the Socratic homework tutor, MasteringPhysics. We show that the measurement of the difficulty of problems for a given student as determined by the time to first correct response, the number of incorrect responses without advice, and hints have high reliability (96%). As an immediate application, we demonstrate how item difficulty can be used to construct an item discrimination measure that would result in predicting the final exam score with a correlation of 0.634.
