Abstract
There is evidence that the gender of high-order school participants (teachers, principals, etc) impacts students. It remains an open question whether same-group peers can act as role models for their classmates. We develop a survey experiment in which individuals are exposed to randomized images of students of different gender excelling in different subjects. Participants are asked whether they think that the image of the student they see could provide good examples for other students in terms of performance, behavior, study and career choices.

Experimental Details

Interventions

Intervention(s)
We designed a survey-based randomized experiment in which students were randomly exposed to profiles of fictitious top-performing students. There were two profile types: a female top performer and a male top performer. Each profile included a picture accompanied by a statement: “A top-performing [male or female] student in your classroom would be an example for you with respect to STEM study.”

Primary Outcomes

Primary Outcomes (end points)
Respondent’s perception/expectation of role model influence on STEM study using a 0-100 scale (with 0 reflecting no influence and 100 strong influence) from a top-performer profile that matches the respondent's gender.
Primary Outcomes (explanation)
Participants were asked to rate, on a 0-100 scale (with 0 indicating no influence and 100 indicating the highest influence), the perceived or expected impact of these top-performing students. To investigate the underlying mechanisms, we then asked participants: “Why do you believe exposure to a [male or female] who excels in your classroom would
affect you?” Respondents were provided with the following answer options: increase in self-confidence, increase in the sense that success is feasible, obtaining information from them, studying together, or other. Respondents were allowed to choose multiple answers.
