Many preschool language-focused interventions attempt to boost language and literacy skills in young children at risk in these areas of development, though the long-term effects of such interventions are not well-established. This study investigated kindergarten language and reading skills, specifically the subcomponents of vocabulary, decoding,…

We investigate the classwide efficacy of INSIGHTS, a universal social-emotional learning intervention for early elementary grades, on observed teacher practices and student behaviors. Twenty-two elementary schools (87% free/reduced lunch) were randomly assigned to INSIGHTS or an attention-control condition. Kindergarten and first-grade classrooms…

The nested data structure inherent in education (i.e. students nested in schools nested in districts) makes intact school matching an appealing approach in observational studies of educational interventions and policies for both theoretical and practical purposes. This paper provides guidance to applied education researchers who are employing…

Results from a cluster randomized trial of the impact of the Tools of the Mind pre-kindergarten curriculum on preschoolers' achievement, self-regulation, and social behavior are reported. Sixty classrooms with four-year-old children (N=877) were assigned to implement either the Tools curriculum (N=32 classrooms; 498 children) or the usual pre-k…

Given that many schools have limited resources and a high proportion of students who present with deficits in early literacy skills, supports aimed at preventing reading failure must be simple and efficient and generate meaningful changes in student learning. We used a randomized group design with a wait-list control to extend the work of Volpe,…

Novel word learning is reported to be problematic for children with severe language impairments (SLI). In this study, we tested electronic storybooks as a tool to support vocabulary acquisition in SLI children. In Experiment 1, 29 kindergarten SLI children heard four e-books each four times: (a) two stories were presented as video books with…

In recent years, governments across the world have increased their investments in early childhood education programs (Britto, Yoshikawa, & Boller, 2011; Engle et al., 2011; Myers, 2006; UNESCO, 2006). This investment in preprimary education reflects the proven value of providing early learning opportunities in promoting later educational…

There is a virtual consensus regarding the types of language processes, interactions, and material supports that are central for young children to become proficient readers and writers (Shanahan et al., 2008). In this study, we examine these supports in both home and school contexts during children's critical transitional kindergarten year.…

Many parents, educators, and policy makers see great potential for leveraging tools like laptop computers, tablets, and smartphones in the classrooms of the world. Although increasing students' technology access may be associated with increased student achievement, there is little research directly investigating objective measures of student…

The transition to school may be particularly difficult for children with developmental disabilities and behavioral difficulties. Such children are likely to experience problems with self-regulation skills, which are critical to school adjustment. Additionally, inconsistent discipline practices and low parental involvement in children's schooling…

In experimental studies, researchers are often interested in secondary research questions that explore important aspects of main findings, such as whether or not program effects vary according to the level of fidelity in which the program has been implemented; or according to the dosage received by individuals participated in the program. In this…

This article reports on a 4-year follow-up study from the Learning Experiences and Alternative Program for Preschoolers and Their Parents (LEAP) randomized trial of early intervention for young children with autism. Overall, participants from LEAP classes were marginally superior to comparison class children on elementary school outcomes specific…

"Un Buen Comienzo" [A Good Start] was a professional development program implemented with prekindergarten and kindergarten teachers in Chilean public schools serving low-income families. In a randomized trial, the program showed moderate to large impacts on classroom quality but no impacts on targeted child outcomes. To unpack these…

This meta-analysis summarizes research on the effects of a comprehensive, interactive web-based software (AXXX) on the development of reading competencies among kindergarteners and elementary students. Findings from seven randomized control trials and quasi-experimental studies undertaken in a variety of contexts across Canada, Australia and Kenya…

In 2009, Vanderbilt University's Peabody Research Institute, with the assistance of the Tennessee Department of Education's Division of Curriculum and Instruction, initiated a rigorous, independent evaluation of the state's Voluntary Prekindergarten program (TN- VPK). TN-VPK is a full-day prekindergarten program for four-year-old children expected…
