Recently there has been renewed debate on the controversial issue of gender differences in math aptitude and achievement. Although women have made great strides in the law, medicine, biological sciences, and social science professions, they have made less progress in graduate programs and professions linked to computer science, physics, engineering, and information technology jobs (Eccles, 2001). Aptitude for math has long been considered a defining difference between men and women, with men having higher standardized achievement scores on SAT and GRE math exams (Halpern, 2004). Yet the most comprehensive reviews have shown very few differences in math aptitude between males and females (Halpern, 2000(Halpern, , 2004. Indeed, research has demonstrated only one gender-consistent difference between men and women in math aptitude and that involves threedimensional mental rotation (favoring men). Similarly, other research has demonstrated a decline in gender differences in math performance on standardized tests, suggesting that the more math and science women are exposed to in school, the better their scores are (Hyde and McKinley, 1997).
