According to the Computing Research Association, the percentage of women earning degrees in computer science peaked in 1984 at just over 37 percent, and has recently fallen to less than 12 percent. The Courant Institute of Mathematical Sciences at NYU wants to show what can be done about it. Courant has specifically designed a new program for this purpose called the G-STEM (Girl's Science, Technology, Engineering, and Mathematics) Summer Camp. Targeting high-aptitude girls in New York City area high schools, it features intensive classes, practical internships, one-on-one adult mentoring, positive peer support, and lots of follow-up activities. The goal is to strengthen the perseverance of young women interested in STEM careers as they transition from high school to college. Funds from this grant provide support for the G-STEM program for three years.
