The purpose of this quantitative ex post facto study was to determine if, and to what extent, differences existed in pre-and-post math scores following the VMath intervention for Title I 6th, 7th, and 8th graders in the Southwestern United States. Three research questions guided this study: (1) is there a statistically significant difference in…

A sample of 496 early childhood teachers was assigned randomly in two phases to a series of professional development (PD) interventions. Phase I intervention was a 14-week course on effective teacher-child interactions. Participants were then re-randomized into Phase II intervention, which consisted of individual, interactions-focused coaching.…

Objective: To determine the impact of a new food scholarship program on nutrient intake and dietary quality. Participants: College students (n = 49), female (78%), single (76%), average age 28 years, and white (49%). Methods: Fruits, vegetables, dairy, meat products and nonperishable foods were distributed twice a month. A one-group pretest…

This study examines the influence of a parent workshop intervention on vocabulary acquisition of at-risk preschool children during parent-child shared storybook reading. Sixty-nine parents were randomly assigned to either treatment or control group. In the treatment condition, parents were taught to implement elaborated vocabulary instruction…

Coaching is becoming widely recognized as a tool to help early childhood educators enhance teaching and build professional skills. Although effective, the use of an external coach can be cost and time prohibitive. This study examined the effectiveness of internal peer coaches as compared to external coaches in implementation fidelity of an…

The purpose of this study was to conduct a pilot randomized controlled trial to evaluate the efficacy of an intervention for enhancing the language development of young children enrolled in home visiting programs. The participants were 59 children (18-30 months old) enrolled in one of three types of home visiting programs. Children's language…

In experimental evaluations of health and social programs, the role of dosage is rarely explored because researchers cannot usually randomize individuals to experience varying dosage levels. Instead, such evaluations reveal the average effects of exposure to an intervention, although program exposure may vary widely. This article compares three…

Background/Context: There is a convergence of evidence that the quality of children's early care and education (ECE) experiences is critical for promoting children's development (Gormley, Phillips, & Gayer, 2008). Curriculum combined with professional development is thought to be the "strongest hope" for promoting quality (Weiland…

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)…

In response to the recession that began in 2007, the U.S. Congress passed, and President Barack Obama signed into law, the American Recovery and Reinvestment Act of 2009 (Pub. Law 111-5). At an estimated cost of $831 billion, this economic stimulus package sought to save and create jobs, provide temporary relief to those adversely affected by the…

Use of multivariate analysis (e.g., multivariate analysis of variance) is common when normally distributed outcomes are collected in intervention research. However, when mixed responses--a set of normal and binary outcomes--are collected, standard multivariate analyses are no longer suitable. While mixed responses are often obtained in…

Preschool parent interventions may produce downstream benefits if initial intervention gains are sustained and improve later socialization experiences. This study explored associations between initial effects of the REDI (Research-based Developmentally Informed) Parent program and later benefits. A randomized trial involving 200 Head Start…

There is a national need for effective interventions to improve school readiness and subsequent achievement in mathematics for students from low-income families. The purpose of this study was to implement and evaluate a 2-year preschool math intervention that began at preschool entry when children were 3 years of age and continued through the end…

Over the course of several years of research, the authors have employed psychophysics, electrophysiological (ERP) and magnetic resonance imaging (MRI) techniques to study the development and neuroplasticity of the human brain. During this time, they observed that different brain systems and related functions display markedly different degrees or…
