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…

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…

Background: We tested the effectiveness of the Go Wild With Fruits and Veggies! (GWWFV) Extension curriculum on increasing fruit and vegetable (FV) intake of third graders. Methods: An intervention study was used testing self-reported FV intake pre/post GWWFV. Recruited schools were randomized to control (12 schools, N = 369, third grade children)…

Classroom quality is critical for young children's learning, yet evidence suggests that the quality of early care and education (ECE) classrooms varies widely, even within federally administered Head Start. This study uses data from the nationally representative Head Start Impact Study to examine variation in children's access to formal and…

Guided by the social cognitive theory, this randomized controlled trial tested the "Make a Move," a provider-led intervention for Head Start parents aimed to produce changes in the outcomes of knowledge, attitude, and behavior of physical activity and healthy eating. Participants were parents of children ages 3-5 years enrolled in a Head…

Attending high-quality early childhood care and education (ECCE) is associated with higher cognitive and social-emotional skills, especially for children growing up in poverty, but access to high-quality ECCE is limited. This study capitalizes on the random assignment design of the Head Start Impact Study to better understand whether the…

Hoping to spur dramatic school turnaround, the federal government channeled resources to the country's lowest-performing schools through School Improvement Grants (SIG). However, prior research on SIG effectiveness is limited and focuses primarily on student achievement. This study uses a difference-in-differences strategy to estimate program…

The National Security Education Program, established under the National Security Education Act of 1991, has had a post-funding service requirement in the Federal Government for undergraduate scholarship and graduate fellowship recipients since its inception. The service requirement, along with the concern that the National Security Education…

This study is a secondary data analysis of data collected on preschool and kindergarten-aged children in Tulsa, Oklahoma in the fall of 2006 to study the effects of school and community-based public early learning programs on children's cognitive and social-emotional outcomes. Children in the study participated in the state-funded pre-k program,…

Researchers have become increasingly interested in programs' main and interaction effects of two variables (A and B, e.g., two treatment variables or one treatment variable and one moderator) on outcomes. A challenge for estimating main and interaction effects is to eliminate selection bias across A-by-B groups. I introduce Rubin's causal model to…

Against the background of a European-wide strategy of governance aimed at improving support for parents and families, the following report details the conceptualization and evaluation of a federal state program in Baden-Württemberg (Germany) which was launched in 2008 to encourage family and parent education. Two program components, a voucher…

Studies of small-scale "model" early-childhood programs show that high-quality preschool can have transformative effects on human capital and economic outcomes. Evidence on the Head Start program is more mixed. Inputs and practices vary widely across Head Start centers, however, and little is known about variation in effectiveness within…

This paper exploits a source of variation in the eligibility for federal nutrition programs to identify the program effects on food insecurity. Children are eligible for the WIC [Women, Infants and Children] program until the day before they turn 61 months old. The result is an age discontinuity in program participation at the 61-month cutoff.…

This dissertation investigates the prevailing No Child Left Behind (NCLB) mandate as an effective platform to improve schools. The data compiled for use in this study represented 426 high schools in Pennsylvania and were retrieved from publicly accessible, state-sponsored sources. The statistical methodologies from the Pennsylvania Value-Added…
