Early mathematics knowledge is a strong predictor of later academic achievement, but children from low-income families enter school with weak mathematics knowledge. An Early Math Trajectories model is proposed and evaluated within a longitudinal study of 517 low-income American children from age 4 to 11. This model includes a broad range of math…

Public charter schools increasingly are part of both the national conversation about education policy and the local urban scene in America. Previous studies of public charter schools have examined their achievement effects focused on both the state and metropolitan levels, and funding disparities focused on the state levels. This is the first…

As part of its effective teaching initiative, the Bill & Melinda Gates Foundation partnered with three urban school districts across the U.S. and a group of four charter management organizations to undertake a strategic set of human capital reforms. A key objective of the "Intensive Partnerships for Effective Teaching" program was to…

Studies show that the mathematics test-score gap is evident at every level of schooling and can be linked to students' earlier performance. For example, a mathematics performance gap was found in children as young as three years of age (Case & Griffin, 1990; Jordan, Huttenlocher, & Levine, 1992). Addressing the mathematics performance gap…

Comparing a small, rural school with sometimes less than 100 students to a massive inner-city school with greater than 2,500 students is crude and untenable. There are simply too many variables. Nonetheless, the No Child Left Behind Act treats these two very different schools the same. When urban and rural schools cannot meet AYP or highly…

The study reported in this article investigated the differential effects of teachers on female, minority, and low-socioeconomic-status (SES) students' achievement. I used data from a 4-year, large-scale, randomized experiment (Project STAR) that was conducted between 1985 and 1989 in Tennessee, in which students and teachers were randomly assigned…
