Teachers' social and emotional learning (SEL) beliefs can impact SEL implementation efforts and consistency in primary and secondary schools. The diffusion of innovations theory is a suitable framework for understanding problems with SEL implementation and diffusion within educational organizations and among teachers over time. The purpose of this…

Issues of social injustice are pervasive in school systems around the world (Welton et al., 2019) with ingrained institutional barriers that hinder students from reaching future successes. As a result, the purpose of this study was to understand the focuses, mindsets, and actions of leaders for social justice working to redress issues of inequity…

Purpose: Having a clear understanding of the types and amounts of classroom literacy learning opportunities is important for contextualizing children's early literacy performance. In this study, we examine the content, context, and management of literacy learning opportunities in a large, geographically diverse sample in the United States. We also…

To improve access to high-quality early childhood education, California has made historic investments in Universal Prekindergarten (UPK), including the California State Preschool Program (CSPP). The state's UPK initiative elevates the importance of multilingualism and the early identification of disabilities in children. This report offers…

California's investment in Universal Transitional Kindergarten (UTK) reflects a commitment to providing access to UTK for all 4-year-olds in public schools by the 2025-2026 academic year. However, the implementation of transitional kindergarten (TK) presents challenges for districts in aligning this new grade coherently with existing grade levels…

Given the recent attention on early childhood mathematics education, it is important to understand how early childhood educators conceptualize the work of mathematics teaching and learning. This article describes a study of preschool educators' conceptions of mathematics teaching and learning in the context of a multi-year professional development…

In 2021, California committed to making transitional kindergarten (TK)--a school-based preschool program initially designed for older 4-year-olds--available for all 4-year-olds by 2025-26. As TK becomes universal, California will need to greatly expand the early learning workforce. This brief provides estimates of how many TK teachers California…

Purpose: The purpose of this project was (1) to collaborate with public preschool programs to adapt, test, and revise the implementation model of an innovative early mathematics intervention, "Pre-K Mathematics" and (2) to determine whether this model makes it possible for local programs to sustain their implementation without reducing…

This study examined the impact of an in-school dance curriculum on the social-emotional development of at-risk preschoolers in a southern California public preschool program. The preschoolers (N = 69) participated in dance for thirty minutes, once a week, over an entire academic year. We compared the Desired Results Developmental Profile (DRDP)…

Objective: To gain insight into the extent of body mass index (BMI) change during an academic year for children with overweight or obesity at entry to an early learning programme with nutrition and physical activity components ("Head Start"). We explored whether meeting with families to discuss weight and nutrition and age of entry in…

Early childhood researchers from across the U.S. came together to form the Early Learning Network (ELN) in 2016 with the mission to identify policies and practices that narrow opportunity gaps and help children maintain early learning success. Early Learning Network teams are excited to share what they have learned--and what it means for early…

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…

With mounting calls for the justice system to declare literacy a civil right, and with a growing emphasis on accelerating reading achievement at the federal, state, and local levels, educational leaders are under increased pressure to implement practices that will not only increase reading achievement but will prove sustainable for years to come.…

The Language Interaction Snapshot (LISn; Sprachman et al., 2009) was used to measure the quantity and quality of language interactions in English and Spanish in 143 preschool classrooms serving Spanish-speaking dual language learners. Both teachers (n = 112) and assistant teachers (n = 92) were included in analyses with a total of 461…

Non-compliance is a challenge for practitioners serving children with and without disabilities. Many interventions have been developed to increase compliance. High-probability request sequences (HPRS), an antecedent-based intervention that is based on behavioral momentum theory, is one way to increase compliant behavior. HPRS includes the…
