Gender Differences in Student Performance in First Semester General Chemistry in Fifteen Week and Five Week Semester Formats

摘要

In this study we investigated both the overall student performance and the DFW rates (the number of students receiving a grade of “D”, “F”, or withdrawing from a class) for both males and females in first semester general chemistry courses over a period of five years. Data was collected from a large southwestern university in the for all of the first semester general chemistry courses offered during this period. The data included 12 fall semester sections, 16 spring semester sections and five summer semester sections with a total sample of 5384 students. The results showed that in the traditional fifteen week semesters the female students significantly outperformed the male students in both overall class averages (ANOVA p0.001), and DFW rates (ANOVA p0.001). However during the summer sessions a startling reversal occurred and the male students significantly outperformed the female students in both overall class averages (ANOVA p0.05) and DFW rate (ANOVA p0.001).
