Abstract Title: How accurately can students’ estimate their performance on an exam and how does this relate to their actual performance on the exam?
Abstract: Research has shown that students' beliefs regarding their own abilities in math and science can influence their performance in these disciplines.  I investigated the relationship between students' estimated performance and actual performance on five exams in a second semester calculus-based physics class.  Students in a second-semester calculus-based physics class were given about 72 hours, after the completion of each of five exams, to estimate their individual and class mean score on each exam.  Students were given extra credit worth 1% of the exam points for each estimating their score correct within 1% of the actual score and another 1% for estimating the class mean score within 1% of the correct value.  I compared students' individual and mean score estimations with the actual scores to investigate the relationship between estimation accuracies and exam performance of the students as well as trends over the semester.
