The purpose of this study is to develop and validate the instrument, Students’ Perceptions on Learning Calculus. The SPLC contains three scales and 31 items. The three scales include Usefulness of Calculus, Professor Efficacy, and Work Ethic. The surveys were given to the students who registered for Calculus I, Calculus II, and Business Calculus at Uconn in spring, 2009. 340 students completed the survey. An exploratory analysis was applied to validate the instrument. Using principal axis factoring with oblique rotation, the analysis suggests that 7 items should be dropped and that the remaining 24 items are best represented by the three factors.
