In a common approach for scaling up effective educational practice, schools adopt evidence-based programs to be implemented with fidelity. An alternative approach assumes that programs should be adapted to local contexts. In this randomized trial of a reading intervention, we study a scaffolded sequence of implementation in which schools first…

Theory and empirical work suggest that teachers' social capital influences school improvement efforts. Social ties are prerequisite for social capital, yet little causal evidence exists on how malleable factors, such as instructional management approaches, affect teachers' ties. In this cluster-randomized trial, we apply a decision-making…

To improve the reading comprehension outcomes of children in high-poverty schools, policymakers need to identify reading interventions that show promise of effectiveness at scale. This study evaluated the effectiveness of a low-cost and large-scale summer reading intervention that provided comprehension lessons at the end of the school year and…

This study examines the effects of four types of reading comprehension questions--immediate, non-immediate, summary, and unanswerable questions--that linguistically diverse and predominantly low-income parents asked their fourth graders on children's text retellings. One-hundred-twenty (N = 120) parent and child dyads participated in a home visit…

Despite widespread use of the program with upper elementary through high school students, there is limited empirical evidence to support its effectiveness. In this randomized controlled trial involving 312 students enrolled in an…
