In what countries do girls do more math?

In what countries do girls do more math?  In recent research featured by the National Science Foundation, Maria Charles, the director of the Broom Center’s Sex and Gender theme, finds that the gender gap in attitudes toward mathematics and mathematically-related jobs is significantly larger in advanced industrial societies.  According to Charles, this surprising gap may result, in part, from different cultural beliefs about gender and about the nature and purpose of educational and occupational pursuits.
