Gifted/talented high school students completed the Mathematical Self-E
fficacy Scale, an instrument developed by Betz and Hackett (1983). Ite
ms in the scale asked the students to indicate their degree of confide
nce regarding successful completion of everyday mathematics tasks, num
ber sequences, mathematics-based college courses, and mathematics prob
lems. The mean self-efficacy ratings given on the items were analyzed
for significant gender differences. Results indicated that males had s
tronger self-efficacy expectations than females on more than one fourt
h of the items, whereas females reported stronger self-efficacy expect
ations on only a few items that involved stereotypical female activiti
es. Implications of the findings for the process of educational decisi
on making are discussed.
