Researchers often presume that it is better to use administrative data from grades 4 and 5 than data from grades 6 through 8 for conducting research on teacher effectiveness that uses value-added models because (1) elementary school teachers teach all subjects to their students in self-contained classrooms and (2) classrooms are more homogenous at…

This article investigates the use of teacher value-added estimates to assess the distribution of effective teaching across students of varying socioeconomic disadvantage in the presence of classroom composition effects. We examine, via simulations, how accurately commonly used teacher value-added estimators recover the rank correlation between…

One of the modifications of the Elementary and Secondary Education Act (known as the No Child Left Behind Act) gave parents of low-income students in low-performing schools a choice of Supplemental Educational Services (SEdS). SEdS include tutoring or other academic support services offered outside the regular school day, at no charge to students…

Fifty-two low performing schools were randomly assigned to receive Spatial-Temporal (ST) Math, a supplemental mathematics software and instructional program, in second/third or fourth/fifth grades or to a business-as-usual control. Analyses reveal a negligible effect of ST Math on mathematics scores, which did not differ significantly across…

This article examines the extent to which impacts of a conditional cash transfer (CCT) program on children's academic outcomes vary by key characteristics associated with families' propensity to earn the rewards offered by the program. We utilize an experimental study of Opportunity NYC-Family Rewards, a comprehensive CCT program in New…

The alignment among standards, assessments, and teachers' instruction is an essential element of standards-based educational reforms. The Surveys of Enacted Curriculum (SEC) is the only common tool that can be used to measure the alignment among all three of these sources (Martone & Sireci, 2009). Prior SEC alignment work has been limited…

Educators and policymakers are paying increased attention to the academic outcomes of students in the middle grades (i.e., Grades 6-8). One reform proposed to improve outcomes for these students is to replace middle schools (with Grade 6-8, 7-8, or 7-9 configurations) with K-8 schools. This longitudinal study evaluated the effects of continuously…

In this study, we compared the effects of two experimental multiple-strategy approaches (content-area comprehension and vocabulary) to typical fourth-grade social studies instructional practices. An 18-week, cluster-randomized study was conducted to estimate effects measured by normative-referenced reading comprehension and vocabulary measures and…

Prior research estimating the effect of Catholic schooling has focused on high school, where evidence suggests a positive effect of Catholic versus public schooling. In this article, we estimate the effect of attending a Catholic elementary school rather than a public school on the math and reading skills of children in kindergarten through fifth…

This article describes 1st-year experimental effects of a large-scale reform providing professional development to elementary school teachers to implement an extended, inquiry-oriented science curriculum. Known as "immersion teaching" because it "immerses" teachers and students in the full cycle of scientific inquiry, this approach developed…
