This project seeks to understand and address gender-based differences in STEM education.
Stereotype threat and feelings of not belonging are suggested as important contributors
of the under-achievement and underrepresentation of women in STEM. Numerous past laboratory
experiments have shown that math-talented female peer role models alleviate the negative
effect of stereotype threat, which should then foster feelings of belongingness in
STEM. The key mechanism underlying the beneficial effect of peer role models seems
to be gender similarity. Accordingly we will engage in an in-depth exploration of
similarity in order to build understanding of the peer role model effect and identify
ways to make peer role models optimally effective.
This project will provide a rich amount of lab-based and prospective, real-world data
that will advance theory and knowledge on ways peer role models can inspire women
to thrive and persist in STEM. Experiments will investigate the impact of increasing
similarity between women and peer role models, examine whether substituting one source
of similarity with another can turn male peers into role models, and attempt to identify
the source or combination of sources of similarity that optimize the peer role model
effect. The research will be conducted at San Diego State University (SDSU) and the
knowledge gained from this research will then be used to inform a prospective field
study conducted in San Diego high school math classrooms. High school is a time when
mathematics-related gender differences begin to emerge and these gender differences
seem to be strong predictors of women's choice to pursue and persist in STEM. This
is also a time when peer influence is particularly strong. Hence, introducing peer
role models into high school math classrooms would be a particularly beneficial method
for reducing the gender gap in STEM.
