We administered an anonymous survey that asked students to report on several aspects of their use of the online
homework. The students received recitation attendance credit
for participation. The survey had 238 respondents, however,
not all participants responded to all items. 138 participants
identified themselves as female and 97 as male; 3 participants chose not to identify their gender if everybody else
reported their gender correctly, these would have had to be
women, but no assumptions were made. 75% of the male
and 74% of the female students stated that they had physics
in high school, so there was basically no difference in high
school physics preparation high school preparation was
found to be a predictor of the size of the gender gap in Ref
