Students (grades 9-11) are randomly assigned to 2 groups: a control group, and a treatment group, with different degrees of saturation at the classroom level: 20%, 50%, and 80%.
The treatment group is exposed to the combination of two treatments:
1. Students receive feedback on a previously carried out Implicit Association Test (IAT), which reveals information on their degree of gender bias (high, medium, low, or no degree of bias) in choosing career paths.
2. Students watch videos about successful women in STEM careers.
