Determining the factors that influence success in physical chemistry can inform efforts to improve teaching methods and increase student understanding. While many studies have examined factors that influence performance in general chemistry courses, very few studies have investigated physical chemistry performance. This current study re-examines correlations to mathematics ability and previous course performance, and also investigates the correlation to homework performance, which has not yet been considered. Correlation coefficients and stepwise regression equations are calculated for the factors influencing performance and the measures of success. This study shows that mathematics ability, as described by an average mathematics grade and number of mathematics courses, is an important predictor for success in the course. In addition, homework and general chemistry performance are shown to positively influence performance in physical chemistry courses. Specific recommendations are given to incorporate these factors into the course structure and thereby improve student learning.
