You're right but the article is pretty interesting nonetheless. With her colleague, Beverly J. Baartmans, she developed a spatial visualization course to help her students develop their spatial cognition skills. The 15-hour program—which uses blocks, sketching, software, and workbooks full of practice exercises—brought the women who took it even with the baseline for men on basic spatial cognition tests and helped boost retention rates for female engineering students by 20 to 30 percent. “If you start with 100 women, you’d expect 50 to graduate as engineers,” Sorby says. “If we give them this intervention, 80 will graduate from engineering.”
