Abstract
This randomized controlled trial (RCT) randomizes middle school students to watch one of the video-recorded interviews with two role models. A growing body of literature has focused on the impact of role models and their underlying mechanisms. The aim of this RCT is to study the marginal effects of different content shared by the role models or the marginal effects of disclosing information about the role models on their role aspirants.

Besides student test scores, this study collects student beliefs about gender and ability, aspirations, behaviors (efforts spent on study, school absence, confidence in achieving goals), and subjective well-being. This study also invites students' parents and head teachers to participate in a baseline survey. Therefore, this study aims to explore the changes in mechanisms due to different content shared by role models, or different information revealed about role models.

Experimental Details

Interventions

Intervention(s)
The classes of the first group (Group1) of recruited schools are randomized to either one of the three treatment arms or one control arm:
- Very successful+background similarities role models,
- Very successful role models,
- Moderately successful+background similarities role models,
- Control: a non-academic class meeting.

The classes of the second group (Group2) of recruited schools are randomized to either one of the three treatment arms or one control arm:
- Complete (Attitude+Behavior) role models,
- Attitude role models,
- Behavior role models,
- Control: a non-academic class meeting.

Primary Outcomes

Primary Outcomes (end points)
Midterm test scores, final exam test scores.
Primary Outcomes (explanation)
Midterm exams took place within one month after the interventions, while the final exams happened more than two months after the interventions.

Secondary Outcomes

Secondary Outcomes (end points)
Student aspirations, beliefs about gender and ability, study efforts, confidence level of achieving goals, school absent days, subjective well-being
Secondary Outcomes (explanation)
