For six semesters, Wayne State University\'s GO-GIRL (Gaining Options-Girls Investigate Real Life) program has been boosting mathematics skills and generating confidence in seventh-grade girls. Now, a National Science Foundation grant awarded to Roosevelt University in Chicago will help implement \"sistership\" programs around the nation. GO-GIRL, offered by the Wayne \'s College of Education , helps middle school girls develop mathematical confidence and skills by integrating mathematics and social science research into a single-gender environment. More than 200 seventh-grade girls in the Detroit metropolitan area have participated since 2002. Sister programs will be started at Howard University, Washington D.C.; University of Pennsylvania , Philadelphia ; Roosevelt University ; and Illinois Wesleyan University , Bloomington , Ill.
