The early years are times of wonder for children. Curious about everything, they seek to explore and understand their world. During these early years, they attempt to interpret their world and make meaning through pretend play, drawing, and conversations with those closest to them. Although these first steps toward literacy may not look much like…

This study examines the potential of educational media to provide preschool-aged dual language learners (DLLs) with vocabulary in a new language. Drawing from dual-coding theory, the current study investigated how three distinct instructional contexts with varying degrees of incidental-intentional vocabulary exposure on screen might facilitate…

Background/Context: Educational policy is informed by multiple stakeholders and actors. Research has focused on understanding how policy decisions are informed and made, as well as how teachers and school leaders take up these policies in their practice. However, few researchers have examined how educational policy is framed for the larger public…

Universal preschool has the potential to close the knowledge gap--but only if we consider how to best teach preschoolers. Unbridled enthusiasm for universal preschool must be balanced with thoughtful consideration of what goes on in these classrooms, and what activities will most support children's learning. Content-centered classrooms help…

Children from diverse backgrounds are able to learn new words from educational media. However, learning is often partial and fragile, leaving much room for uncovering strategies that can increase the efficacy of educational media in supporting children's vocabulary knowledge. The present study investigated one such strategy--repeated viewing of…

The purpose of this study was to investigate the influence of digital and non-digital storybooks on low-income preschoolers' oral language comprehension. Employing a within-subject design on 38 four-year-olds from a Head Start program, we compared the effect of medium on preschoolers' target words and comprehension of stories. Four digital…

Educational screen media is increasingly salient in the lives of young children. Research affirms preschool-aged children can learn content from media when they attend to it, however less is known about how specific screen-based pedagogical supports (SBPS) might draw children's attention. Using eye-tracking methodology, the current study examines…

This study examined the efficacy of a shared book-reading approach to integrating literacy and science instruction. The purpose was to determine whether teaching science vocabulary using information text could improve low-income preschoolers' word knowledge, conceptual development, and content knowledge in the life sciences. Teachers in 17…

The purpose of this study was to support teachers' child-directed language and student outcomes by enhancing the educative features of an intervention targeted to vocabulary, conceptual development and comprehension. Using a set of design heuristics (Davis & Krajcik, 2005), our goal was to support teachers' professional development within the…

The purpose of this design experiment was to research, test, and iteratively derive principles of word learning and word organization that could help to theoretically advance our understanding of vocabulary development for low-income preschoolers. Six Head Start teachers in morning and afternoon programs and their children (N = 89) were selected…

This meta-analysis examines the effects of vocabulary interventions on pre-K and kindergarten children's oral language development. The authors quantitatively reviewed 67 studies and 216 effect sizes to better understand the impact of training on word learning. Results indicated an overall effect size of 0.88, demonstrating, on average, a gain of…

The purpose of this study was to examine the hypothesis that helping preschoolers learn words through categorization may enhance their ability to retain words and their conceptual properties, acting as a bootstrap for self-learning. We examined this hypothesis by investigating the effects of the World of Words instructional program, a supplemental…

Recognizing the importance of starting early, the purpose of our article is to examine if and how vocabulary is taught in commercially prepared early literacy curriculum for pre-K. Ten curriculum programs are reviewed to determine the prevalence of vocabulary instruction and the pedagogical practices used to support the learning of words and their…

Examines the impact of an intervention targeting economically disadvantaged children that flooded over 330 child-care centers with high-quality children's books and provided 10 hours of training to child-care staff. Examines the project's impact and gives support for the physical proximity of books and the psychological support to child-care staff…
