Unfortunately, due to scheduling constraints, the MPEX
Ref. 14 and the FCI Ref. 15 were not administered as
pretest. Instead, those tests were administered after the third
test in the seventh week of the semester, following instruction on force, momentum, and energy. The students received
recitation attendance credit for participation. Male and female students both had an average MPEX “score” of 166
out of 34. The average FCI scores differed, though not
statistically significant: male students had an average score
of 18.86 out of 30, while female students had 14.85.
Figure 2 shows the FCI score distributions: there is a wide
spread of scores, but the highest scores are almost exclusively achieved by male students, while the lowest scores are
mostly from female students
