When I was an undergraduate student in Computer Engineering major in Sharif University of Technology, in Iran, I was always wondering that among the department of Computer Engineering's student, why the proportion of female students willing to have TA or RA positions is less than male students, Although the numbers of female and male students enrolled in program was almost the same. When I looked at the faculty level, I saw that among 30 faculty members there was just one woman. If you look further in the society, this problem exists as well.
