Editor's Notes
- FCI is a well-established conceptual test developed by Hestenes and Halloun at University of Arizona as tool to measure students’ understanding of Newtonian mechanics. Students are compelled to choose between Newtonian concepts of force an common misconceptions they might have. Routinely administered as Pre-test /Post-test to be used as measure of how course has affected student understanding. Original FCI has 29 questions - using revised and extended version with 33 questions
- Combined 5 years worth of data subsequently split by males and females to compare scores both when they enter the university - week 1, and after 1 semester of teaching. Graph - mean percentage scores on FCI on y-axis, and Pre-test / Post-test results on x-axis. Values above each bar represent the absolute scores out of 33 for each gender. What I have defined here is the Gender Gap, which we have defined as the mean avg score for M - mean avg score F Pre-test: statistically sig gender gap, Males 12% higher than incoming females Post-test: gender gap remains sig, Males 4% higher than females, Females have higher normalised gain than males after one semester of teaching
- If we look at each question of the FCI individually we see that males, in green, outperform females, in blue on every question, with some questions showing greater differences than others. In the pre-test it was found that all but 8 questions had a statistically significant difference between males and females
- Taking a quick look at the post-test results we see that both genders have improved overall in each question and there is a large decrease in the gender gap between males and females BUT males are still outperforming females in almost every question, but fewer questions show a significant difference (22/33 not significant)
- FCI has been similarly used at many institutions in NA. Compare these results to research carried out by Mazur group at Harvard Also saw a decrease in the gender gap after one semester but concluded that for fully interactive teaching classes there was a complete elimination of gender gap after one semester. Marked differences in composition of introductory physics course cohorts between NA and UK
- F 68.18% M 60.41%
- F 52.06% M 50.98%
