The response to the COVID-19 pandemic impacted educational systems throughout the world. School closures, virtual schooling, and strict safety protocols for in-person learning changed instructional approaches to teaching. These changes were particularly disruptive in early childhood education which relies on play-based learning to support…

The problem that inspired this study is that Turkish students' mathematics rankings on global exams such as The Program for the International Students Assessment (PISA) and Trends in International Mathematics and Science Study (TIMMS) had been below the average for many years, a problem that may have rooted in children's early experiences with…

We report on a scaled-up mathematics intervention in preschool classes (children age six) in Sweden. In the intervention, teachers at seven schools in four municipalities implemented the Thinking, Reasoning and Counting in Preschool Class (TRC) teacher guide in their teaching of 254 students. Results are compared to a previous randomized…

The study of the process of becoming a student is currently a key issue in educational science and psychology research. However, there is no consensus on its definition. Based on a redefinition of the concept from a psychodevelopmental and contextual perspective (Bronfenbrenner, 2005; Malrieu, 1973), the aim of this study is to document the inter-…

Background: Pre-k convergence refers to the tendency for the positive effects of pre-k on children's academic skills to diminish over time, observed across decades of observational and experimental studies (Ansari et al., 2020). Researchers have tested multiple mechanisms to explain convergence, with mixed results; none of the proposed mechanisms…

Background: Publicly funded four-year-old preschool (or 4K) programs have expanded over the past several decades (Friedman-Krauss et al. 2021). Many high-quality preschool programs lead to gains in academic and social skills for students (Cascio and Schanzenbach 2013; Gormley and Gayer 2005; Weiland and Yoshikawa 2013; Wong et al. 2008),…

Michigan's Great Start Readiness Program (GSRP) is a state-funded pre-K program that serves at risk four-year-old children across the state. Utilizing longitudinal data from 1,394 children in a mid-sized urban school district, we conducted regression analyses and piecewise linear growth models to examine the growth trajectory of GSRP children and…

The purpose of this study was to examine the efficacy of Imagine Learning's MyPath program on student mathematics and reading achievement growth. This study examined achievement growth trajectories of kindergarten students in one suburban Midwestern district in the 2022-23 school year. NWEA MAP mathematics and reading scores served as the main…

Given the well-documented relation between executive functioning (EF) and math skills in preschool, there is a surprising lack of evidence on early intervention approaches that have successfully, and consistently, impacted both EF and math skills. To confront this gap in the literature, Study 1 explored why an established EF intervention impacted…

The purpose of this study was to gain greater understanding of leadership practices in schools for D/HH students. This study specifically looked at the Four Paths Model of Leadership and sought to explore the variables within the Rational Path Model and school leadership influence on student learning through academic culture, a general term used…

The COVID-19 context has created the most severe disruption to education systems in recent history. Its impact on child development was estimated comparing two cohorts of 4- to 6-year-old Uruguayan children: control (n = 34,355, 48.87% girls) and COVID cohort (n = 30,158, 48.95% girls) assessed between 2018 and 2020 in three waves, by a routinely…

Currently available measures of PreK classroom quality inconsistently predict gains in children's outcomes. Extant measures may not capture the full range of instructional practices--including the degree to which children are exposed to rich content and cognitively demanding instruction--that are important for supporting the development of early…

Pre-kindergarten (pre-k) is thought to have both direct and indirect effects on children's outcomes in early elementary school. Direct pre-k effects consistently include moderate to large gains in academic skills and sometimes include increases in problem behaviors that affect acquisition of skills in school. Indirect pre-k effects assume that…

Nearly all states with public prekindergarten programs use mixed-delivery systems, with classrooms in both public schools and community-based settings. However, experts have long raised concerns about systematic inequities by setting within these public systems. We used data from five large-scale such systems that have taken steps to improve…

This study investigates the relationships between preschool quality and children's learning and development from fall to spring of 1 school year through the analysis of child- and program-level data from approximately 70,000 children, ranging in age from 4.5 to 5.5 years old, in 1,700 Quality Counts California (QCC) rated preschool programs, the…
