Pre-kindergarten (Pre-K) improves the school readiness of all children, but less is known about whether associations between enrollment in Pre-K and different indicators of social-emotional and executive functioning (EF) skills are sustained as children move into and across elementary school. The current study examines associations between…

Parents play an important role in creating home language environments that promote language development. A nonequivalent group design was used to evaluate the effectiveness of a community-based implementation of LENA Start™, a parent-training program aimed at increasing the quantity of adult words (AWC) and conversational turns (CT). Parent-child…

Early education is replete with debates about "academic" versus "play" approaches. We evaluated 2 interventions, the "Building Blocks" (BB) mathematics curriculum and the BB synthesized with scaffolding of play to promote executive function (BBSEF), compared to a business-as-usual (BAU) control using a 3-armed cluster…

Studies have shown that math skills in early childhood are uniquely and strongly predictive of later outcomes across a range of domains and well into adulthood, including the likelihood of graduating from high school and college completion. The Making Pre-K Count and High 5s studies were designed to rigorously test the short- and long-term effects…

This study's goal was to understand the extent to which providing access to media resources focused on critical science and engineering concepts can help children living in low-income households learn. The resources examined were from the PBS KIDS multi-platform property "The Cat in the Hat Knows a Lot About That!" Researchers found that…

Preschool is an important educational setting for child development, and problem behavior is a prevalent barrier within this setting. Preschool teachers have expressed the need for evidence-based classroom management interventions to address problem behavior. Class-Wide Function-Related Intervention Teams (CW-FIT) is an intervention that…

Self-regulation and academic skills in kindergarten are strong predictors of later achievement. However, many children enter kindergarten without adequate levels of these skills, often because of limited participation in early childhood education. The current study examined a kindergarten readiness summer program (Bridge to Kindergarten; B2K) that…

In research on language development by bilingual children, the early language environment is commonly characterized in terms of the relative amount of exposure a child gets to each language based on parent report. Little is known about how absolute measures of child-directed speech in two languages relate to language growth. In this study of…

This cluster randomized trial evaluated the impact of the Promoting Alternative Thinking Strategies (PATHS) curriculum on children's psychological wellbeing, peer social support, and school connectedness. Forty-five schools in England were randomly assigned to implement PATHS or continue their usual provision for 2 years. The trial sample was…

This project tested the effects of adding instruction of trios of children in patterning, mathematics, early literacy, or social studies to ongoing instruction in kindergartens. Children were randomly assigned to trios which were randomly assigned to one of four kinds of instruction. A quarter of the trios received patterning instruction with a…

Children from low-income families are at greater risk for poor social-emotional development and physical health and may be in need of intervention. This study examined the extent to which the "Positive Action" ("PA") preschool lessons improved low-income children's social-emotional competence and health behaviors. Mixed…

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…

Interactive book reading (IBR) has proven effective for increasing children's lexicons with most of the results based on students' learning of nouns. Little is known about the application of IBR to instructional verbs (i.e., words used during the instruction of academic content). To address this gap, 122 prekindergarten children were recruited…

Recent findings have suggested that adults' and children's approximate number system (ANS) acuity may be malleable through training, but research on ANS acuity has largely been conducted with adults and children who are from middle- to high-income homes. We conducted 2 experiments to test the malleability of ANS acuity in preschool-aged children…

A randomized controlled trial was used to examine the impact of an attachment-based, teacher-child, dyadic intervention (Banking Time) to improve children's externalizing behavior. Participants included 183 teachers and 470 preschool children (3-4 years of age). Classrooms were randomly assigned to Banking Time, child time, or business as usual…
