Academic achievement in the nation's lowest performing schools is troubling. Despite improvements in students' overall academic achievement over the past few decades, proficiency gaps in reading and mathematics remain across income, racial, and ethnic groups. One promising strategy for reducing achievement gaps is to expand the school day, often…

Background: Students who do not acquire social and emotional skills are at risk for a range of negative outcomes that include emotional and behavioral disabilities, lower school achievement and school failure, peer rejection, substance abuse, and school dropout (Downer & Pianta, 2006; Riggs et al., 2006 Quinn & Poirier, 2004). Tools for…

High school graduation rates remain unacceptably low in the U.S., especially among disadvantaged youth (Chapman, Laird, Ifill, & KelalRamani, 2011; Stillwell, 2010), with troubling implications for future earnings and employment status (Bureau of Labor Statistics, 2012). Check & Connect (C&C) is an individualized program that pairs…

This paper examines the "ecological validity" of a randomized controlled trial (RCT) conducted in 42 high schools to measure the impact of a content literacy program. This study of comparable schools implementing the same program in different contexts highlights characteristics that are often not attended to in rigorous effectiveness…

Reading skills are the key building blocks of a child's formal education. Yet, the national statistics on literacy attainment are profoundly distressing: two out of three American fourth graders are reading below grade level and almost one third of children nationwide lack even basic reading skills. This study reports on an evaluation of the…

Nationally, two-thirds of high school students are unable to read and comprehend complex academic materials, think critically about texts, and synthesize information from multiple sources, or communicate what they have learned. Without a substantial change in their academic literacy, U.S. high school students face continued academic problems in…

The ESEA Blueprint for Reform states that teachers need "effective, ongoing, job-embedded, professional development that is targeted to student and school needs… [and] aligned with evidence of improvements in student learning." Unfortunately, the professional development approaches advocated, though sensible and compelling in theory,…

The National Center for Research on Early Childhood Education's (NCRECE) program of research is a series of experimental studies of specific approaches to training early childhood (EC) educators to be effective in implementation of curriculum and instructional interactions focused on promoting language and literacy skills, two domains that operate…

The BioBridge Professional Development model was created to bring current and relevant science into the high school classroom. The purpose of this intervention was to connect teachers with relevant science and to create innovative, hands-on activities that engage students, with the goal of increasing student interest in STEM careers. To this end,…

The Scale-Up Pre-K Mathematics project, was conducted at a customary program-wide level of scale in Head Start and state-funded preschool programs in California and Kentucky/Indiana. The objectives of this randomized field trial were twofold: (1) to determine whether the intervention, the Pre-K Mathematics curriculum, continues to be effective…

This study focuses on how the treatment effects of a teacher professional development initiative in science differed by school capacity. In other words, the authors are primarily concerned with treatment effect heterogeneity. As such, this paper complements ongoing evaluation of the average treatment effects of the initiative over time. The…
