  We extend on previous research on the Force Concept Inventory (FCI) given to
first year classical mechanics students (N=66 students, over four years) pre
and post score, for students on an international (global) course at Osaka
University. In particular, we revisit the notion of "polarisation" in
connection with the six polarisation-inducing questions in the FCI and examine
its gender aspect. Our data suggest that this phenomenon is not unique to one
gender. Furthermore, the extent by which it is exhibited by males may differ
from that of females at the beginning (pretest) but the gap closes upon
learning more about forces (posttest). These findings are for the most part,
complemented by our result for the FCI as a whole. Although the differences in
means for males and females suggest a gender gap, statistical analysis shows
that there is no gender difference at the 95% confidence level.
