Emerging research suggests English and Spanish proficiencies of young Latine dual language learners (DLLs) are heterogeneous, including subgroups characterized by varying levels of English and Spanish dominance and proficiencies. However, there is limited understanding of contextual factors associated with the formation of DLL profiles. This study…

Center-based early care and education (ECE) is important for promoting positive early development and supporting families by providing child care so parents can work. However, the center-based supply varies substantially in terms of funding sources, indicators of quality, and services offered; and many families experience a lack of equitable…

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 current paper reports long-term impacts of the Chicago School Readiness Project (CSRP) on measures of achievement, cognitive functioning, and behavioral regulation taken toward the end of students' high school careers. The CSRP was a self-regulation-focused early childhood intervention implemented in Head Start centers serving high-poverty…

Differences in children's mathematics knowledge are evident at kindergarten entry, favoring children who have greater access to economic resources. Fostering preschoolers' mathematics learning at home and in classroom settings, through games and other developmentally appropriate activities, is of great interest to educators, early childhood…

In the present study, we investigated the relative impact of age- versus schooling-related growth in school readiness skills using four modeling approaches that leverage natural variation in longitudinal data collected within the preschool year. Our goal was to demonstrate the applicability of different analytic techniques that do not rely on…

Despite strong evidence self-regulation skills are critical for school readiness, there remains a dearth of longitudinal studies that describe developmental trajectories of self-regulation, particularly among low-resource and underrepresented populations such as Spanish-English dual-language learners. The present study examined individual…

Research Findings: Children's oral language skills lay the foundation for later literacy and can be fostered through responsive conversations with teachers. However, such conversations are rare in preschool, particularly between teachers and dual language learners (DLLs), or students who speak a minoritized language at home. DLLs benefit when…

Children's relationships with their teachers are critical for classroom-based learning, but children growing up in poverty may be at risk for lower-quality relationships with teachers. Little is known about how changing schools, one poverty-related risk, affects teacher-child relationships. Using growth curve models that control for a host of…

A socioeconomic status (SES) gap in mathematical knowledge emerges early and widens prior to school entry. To address this gap, a curricular intervention, "Pre-K Mathematics," was developed and found to be effective in prior efficacy research. In the present project, the next step was taken in evaluating this intervention. Specifically,…
