To provide a landscape of mathematics activities children experience in U.S. preschool and kindergarten classrooms, we observed time children spent in mathematics activities (and -- as a contrast -- literacy) in 101 geographically diverse early childhood classrooms in seven U.S. states. We also observed what mathematics content, grouping…

The overall aim of the current investigation was to develop and validate the initial version of the Minnesota Inference Assessment (MIA). MIA is a web-based measure of inference processes in K-2. MIA leverages the affordances of different media to evaluate inference processes in a nonreading context, using age-appropriate fiction and nonfiction…

Educators have embraced the promotion of social emotional development, student well-being, and mental health as essential educational objectives to promote academic readiness and growth. To address known research-to-practice gaps and limited availability of evidence-based, universal high school programs, we took a community-based participatory…

The construct of reading comprehension has changed significantly in the 21st century, however, some test designs have not evolved sufficiently to capture these changes. Specifically, the nature of literacy sources and skills required has changed (wrought primarily by widespread use of digital technologies). Modern theories of comprehension and…

Although basing instruction on learning trajectories (LTs) is often recommended, there is little direct evidence regarding the premise of an LT approach--that instruction should be presented (only) one LT level beyond a child's present level. We evaluated this hypothesis in the domain of early shape composition. One group of preschoolers, who were…

Despite the prevalence of educational apps for children, there is little evidence of their effectiveness for learning. Here, children were asked to learn ten new words in a narrative mobile game that requires children use knowledge of word meanings to advance the game. Study 1 used a lab-based between-subjects design with middle-SES 4-year-olds…

The framework and tools used for classroom assessment can have significant impacts on teacher practices and student achievement. Getting assessment right is an important component in creating positive learning experiences and academic success. Recent government reports (e.g., United States, Australia) call for the development of systems that use…

With a qualitative approach drawing from four focus groups, this study explored what aspects of preschool are valued most by 30 low-income Latino/a immigrant parents with children enrolled in a state-funded preschool program in Texas. Beyond the push and pull factors of necessity, convenience, and supply, parents reported valuing the…

Selective sustained attention (SSA) is crucial for higher order cognition. Factors promoting SSA are described as exogenous or endogenous. However, there is little research specifying how these factors interact during development, due largely to the paucity of developmentally appropriate paradigms. We report findings from a novel paradigm designed…

We investigated direct and indirect effects of component skills on writing (DIEW) using data from 193 children in Grade 1. In this model, working memory was hypothesized to be a foundational cognitive ability for language and cognitive skills as well as transcription skills, which, in turn, contribute to writing. Foundational oral language skills…
