Abstract Title: Variation Of Pretest Results From Dozens Of Classes And Thousands Of Students
Abstract: As part of the tutorial component of introductory calculus-based physics at the University of Washington, students take weekly "pretests." Pretests are so named because they precede each tutorial, but they are frequently administered after lecture instruction. For some pretest question we have accumulated thousands of responses, from dozens of course sections representing different conditions with respect to class composition, prior instruction, etc. In this paper three questions serve as representative examples. For each question, we examine the variation in student performance (defined as the proportion of students who answered correctly) across all sections for which data are available, and for subsets of the data categorized according to the amount of relevant prior instruction each class had received.
