Research indicates that vocabulary development--linked to conceptual growth and comprehension--predicts student academic achievement throughout the elementary, middle, and high school grades. Intelligence increases as vocabulary continues to develop. The iSpy program provides high-quality, content-rich classroom books, learning manipulatives, and…

Interventions for promoting physical activity designed specifically for preschoolers with autism spectrum disorders (ASD) are lacking, which is problematic given the low rates of physical activity among this population. This study used a stakeholder-engaged approach to adapt the Wellness Enhancing Physical Activity for Young Children (WE PLAY)…

In addition to its influences across economic, geopolitical, and social spheres, globalization has given rise to the notion of a 'global citizen' who is able to understand a shifting and more internationalized world while moving fluidly through it. Education has been trumpeted as the means to achieve this globally-aware citizenry, leading to an…

Social-emotional learning (SEL) programs are frequently evaluated using randomized controlled trial (RCT) methodology as a means to assess program impacts. What is often missing in RCT studies is a robust parallel investigation of the multi-level implementation of the program. The field of implementation science bridges the gap between the RCT…

Understanding digital supports for early learning is paramount for school readiness and later mathematics learning. We present results from a randomized control trial evaluating a digital app (Measure Up!) and a parent companion app (Super Vision) designed to teach children measurement concepts, a skill that many teachers do not feel comfortable…

This study describes the implementation and findings from a consultation process designed to enhance the professional development (PD) offered to teachers working in Virginia's state-funded preschool program. A PD Rubric was developed to translate research on effective PD (i.e., PD practices linked to positive changes in teacher practice and/or…

Achieving high-quality preschool at scale is challenging; to do so likely entails a combination of program standards, teacher qualifications and compensation, on-site quality monitoring, and professional development (PD). This study aims to examine the impact of investments in PD within the context of an expansion of universal preschool in one of…

RFA's three-year mixed methods evaluation of Children's Literacy Initiative's language and literacy supports found positive impacts despite higher-than-typical teacher turnover. In pre-K centers receiving CLI supports, teachers were more able to implement effective instructional practices and created richer classroom literacy environments, and…

Given the dearth of research on early numeracy interventions in low- and middle-income countries, this paper presents the instructional methodology and impact results of the Tayari program. Tayari is a preprimary intervention in Kenya (2014-2019) that prepares children aged four and five for entry into primary school by providing materials for…

Young children are gaining access to and enrolling in preschool programs across the country in increasing numbers. Unfortunately, the quality of these programs varies tremendously. The highest quality programs disproportionately serve children from the most advantaged homes. By contrast, lower quality and less effective programs disproportionately…

This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language…

This article draws on qualitative evidence from an evaluation of the "Greater Tomorrow" Crèche and Ballyhaunis Community Preschool in Ballyhaunis, Co Mayo, Ireland in 2016. The article focuses on the approach to practice and the underlying ethos of these two services, reflecting a clearly articulated respect for diversity and the…

Georgia has been at the forefront of the pre-kindergarten movement since implementing its pre-k program in 1992 and creating the nation's first state-funded universal pre-k program in 1995. Georgia's Pre-K, administered by "Bright from the Start: Georgia Department of Early Care and Learning" (DECAL), aims to provide high-quality…

The primary purpose of the accompanying final study was to evaluate the impact of two professional development models on teacher-child interactions in Georgia's Pre-K classrooms. Teachers were randomly selected to participate and were randomly assigned to one of the professional development conditions or to a control group. Because of this…

This paper describes a self-study research project that focused on our experiences when planning, teaching, and evaluating a course in initial teacher education. The theoretical framework of technological pedagogical content knowledge (TPACK) was used as a conceptual structure for the self-study. Our understanding of the framework in relation to…
