The purpose of this project is to develop analytic strategies that incorporate instrumental variables for identifying and estimating the average treatment effect (ATE), the moderated ATE, the mediated ATE, and the moderated mediation effects in a single-site randomized trial where the moderator of theoretical interest is individual predisposition for compliance. The research team will also develop approaches to causal moderation and mediation in cluster randomized trials to take into account...

The aims of this project are to examine the role of pressure as a factor underlying persistent achievement gaps in mathematical reasoning skills and to test a malleable factor for reducing those gaps: making worked examples visible while engaging students in mathematical reasoning. Most of the research exploring the effects of anxiety and pressure on academic performance focuses on testing situations. Through this project, the research team will extend this work by looking at whether anxiety...
