Examines recent data on sex-related differences in science and mathematics achievement, discussing meta-analyses findings on attitudes, career choice, life/physical science preferences, and motivation. Indicates that spatial visualization appears to be very important and that girls more often attribute success to luck rather than skill. (DH)

This study examined the level of realism inherent in videotape and computer graphics display systems by comparing the ability of third graders, middle schoolers, and university students to estimate end states of visual transformations of spatial tasks. Their preferences for working with videotaped or computer-generated materials are also…

Reported are two separate but related longitudinal studies of two variables strongly associated with sex-related differences in mathematics achievement and enrollment, namely spatial visualization and confidence in learning mathematics. First, boys (N=33) and girls (N=36) in grades 6-8 who were discrepant in their spatial and verbal skills were…
