The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

We present main effects of treatment and moderating effects of student background on science and engineering outcomes for grades 3-5 children participating in an engineering intervention. Data is from a large-scale randomized-controlled trial of two matched pairs (intervention and comparison) of engineering units. The intervention curriculum…

Many students lose knowledge and skills over the long summer break, and research suggests that low-income students fall further behind over the summer than their higher-income peers. Voluntary summer learning programs may provide an opportunity to stem summer learning loss and give struggling students additional learning opportunities. The Wallace…

Prior research has determined that low-income students lose more ground over the summer than their higher-income peers. Prior research has also shown that some summer learning programs can stem this loss, but we do not know whether large, district-run, voluntary programs can improve students' outcomes. To fill this gap, The Wallace Foundation…

Many parents, educators, and policy makers see great potential for leveraging tools like laptop computers, tablets, and smartphones in the classrooms of the world. Although increasing students' technology access may be associated with increased student achievement, there is little research directly investigating objective measures of student…
