Discrimination in measures of knowledge monitoring accuracy

Knowledge monitoring predicts academic outcomes in many contexts. However,measures of knowledge monitoring accuracy are often incomplete. In the currentstudy, a measure of students’ ability to discriminate known from unknowninformation as a component of knowledge monitoring was considered. Undergraduatestudents’ knowledge monitoring accuracy was assessed and used to predict finalexam scores in a specific course. It was found that gamma, a measure commonlyused as the measure of knowledge monitoring accuracy, accounted for a small, butsignificant amount of variance in academic performance whereas thediscrimination and bias indexes combined to account for a greater amount ofvariance in academic performance.
