he book is based on interviews with more than 100 computer science students of both sexes from Carnegie Mellon University over a period of four years, as well as classroom observations and conversations with hundreds of college and high school faculty. The interviews capture the dynamic details of the female computing experience, from the family computer kept in a brother's bedroom to women's feelings of alienation in college computing classes. The authors investigate the familial, educational, and institutional origins of the computing gender gap. They also describe educational reforms that have made a dramatic difference at Carnegie Mellon--where the percentage of women entering the School of Computer Science rose from 7% in 1995 to 42% in 2000--and at high schools around the country.
