A pilot program was developed to study the use of computer software to enhance spatial skills presumed to be related to success in calculus. In particular, it addressed the effects of such a program on female and minority students. The objectives were to (a) explore the effect of the use of the computer on enhancing spatial skills, (b) relate spatial ability to success in calculus, (c) consider gender and ethnic differences, and (d) explore other factors which might influence spatial skill development. Results indicated that the combined effect of the computer, drawing/drafting, and gender variables produced a significance level under .01 and were able to explain 31% of the variance in test scores. Both gender and the drawing/drafting variable reached significance on the mean calculus test scores.
