A randomized experiment that measures the impact of a social policy in a sample of the population reveals whether the policy will work on average with universal application. An experiment that includes only the subset of the population that volunteers for the intervention generates narrower "proof-of-concept" evidence of whether the…

Research questions regarding how, for whom, and where a treatment achieves its effect on an outcome have become increasingly valued in substantive research. Such questions can be answered by causal moderated mediation analysis, which assesses the heterogeneity of the mediation mechanism underlying the treatment effect across individual and…

The Upward Bound Math and Science (UBMS) program at Temple University (TU) seeks to guide first-generation, low-income high school students from Philadelphia in their quest to obtain postsecondary STEM degrees that lead to related careers. This study aims to evaluate the efficacy of the program by analyzing its students' performance in light of…

Head Start is a national program that helps young children from families with low incomes get ready to succeed in school. It does this by working to promote their early learning and health and their families' well-being. The Head Start Family and Child Experiences Survey (FACES) provides national information about Head Start programs and…

Panel or grouped data are often used to allow for unobserved individual heterogeneity in econometric models via fixed effects. In this paper, we discuss identification of a panel data model in which the unobserved heterogeneity both enters additively and interacts with treatment variables. We present identification and estimation methods for…

This technical supplement to the Supplemental Nutrition Assistance Program (SNAP) Employment and Training (E&T) evaluation final reports presents details of the technical approach used for creating analysis variables and estimating impacts of treatment group services on outcomes, including employment, earnings, and SNAP participation. It also…

When No Child Left Behind (NCLB) became law in 2002, it was viewed as an effort to create uniform standards for students and schools across the country. More than a decade later, we know surprisingly little about how states actually implemented NCLB and the extent to which state implementation decisions managed to undo the centralizing objectives…

This research critically analyzes the introduction of the Express Entry system in Canada, requiring foreign nationals to submit an Expression of Interest (EOI) and wait for an invitation before being allowed to apply for permanent residence. Drawing on available empirical data, I argue that this reform jeopardized international students' chance to…

Prevent-Teach-Reinforce for Young Children (PTR-YC) is a standardized model of positive behavior support designed to deliver individualized interventions for preschool-aged children with severe and persistent challenging behaviors. A randomized controlled trial was conducted to compare effects of PTR-YC with those of a "business as…

A growing body of research has been documenting the pivotal role that philanthropic funding plays in advancing state and local charter school reform. However, there is little understanding of the geographic flow of these funding patterns and the market, policy, and organizational conditions that have concentrated funding in some clusters of states…

Purpose/Objectives: This study assessed current practices and attitudes of school nutrition program (SNP) management staff regarding free and reduced-price (F-RP) meal application and verification in SNPs. Methods: Stratified, randomly selected 1,500 SNP management staff in 14 states received a link to an online questionnaire and/or a printed…

The present study examined representational and non-representational activities in which children in a Head Start classroom participated. This was an investigation from the perspective of cultural-historical activity theory of how components (e.g. artifacts and division of labour) of classroom activities vary across and within types of activities.…

Kindergarten has become increasingly academically oriented, and U.S. kindergarten teachers are increasingly called upon to implement policies that require assessment and promote accountability. However, little recent research has focused on kindergarten teachers' beliefs about kindergarten readiness. The authors examined teachers' beliefs related…

Research Findings: The current study examined the impact of daily classroom computer use on the cognitive development of preschool children in 14 urban Head Start classrooms. The sample consisted of 208 predominantly African American low-income children with a mean age of 48.8 months. A quasi-experimental design was used in which 7 classrooms had…

Using nationally representative data from the Family and Child Experiences Survey 2009 cohort (n = 2,842), this study examined the implications of 3- and 4-year-old's absences from Head Start for their early academic learning. The findings from this study revealed that children who missed more days of school, and especially those who were…
