The Classroom Learning Activities Checklist (CLAC) is a brief classroom observation measure that assesses task-oriented and self-regulated learning in early childhood environments. We assessed the tool's dimensionality and validity in predicting prekindergarten (PreK) learning gains. The study sample is from the Midwest Child-Parent Center (MCPC)…

Sound assessment tools are needed to evaluate effects of mathematics interventions that familiarize children with early mathematics concepts before they enter the formal school system. We developed a short version of an existing early mathematics tool based on analyses of data collected in a nationally representative Danish sample. Research…

The article presents a new adaptation programme entitled 'With a smile to school' for pupils of the first year at primary schools. The adaptation programme comprises several methods and measures which are focused on the regulation of pupils' adaptation process. The efficiency and effectiveness of the adaptation programme were verified through an…

This paper studies the impact of PROBEMS, a scholarship program in Mexico aimed at improving graduation rates and test scores among upper secondary school students from poor backgrounds. The identification strategy is the random allocation into the program, which took place in 2009. The strategy allows measurement of the effects of PROBEMS on test…

Professional development (PD) is a potentially important mechanism for enhancing classroom practices and children's learning. In this large-scale randomized controlled trial, we examined the effectiveness of language and literacy PD, with and without coaching, offered at scale to early childhood educators (n = 546) across one state. Relative to…

Children's school readiness as they enter kindergarten is an important predictor of their academic success and ultimately their long-term health and economic outcomes. Research shows that participation in high-quality early childhood education helps preschoolers gain the foundational language and literacy skills as well as the social-emotional…

This study is a randomized control trial of full- versus half-day pre-kindergarten in a school district near Denver, Colorado. Four-year-old children were randomly assigned an offer of half-day (four days/week) or full-day (five days/week) pre-k that increased class time by over 600 hours. The offer of full-day pre-k produced substantial, positive…

Children's lexical processing speed at 18 to 25 months of age has been linked to concurrent and later language abilities. In the current study, we extend this finding to children aged 36 months. Children (N = 126) participated in a lexical processing task in which they viewed two static images on noun trials (e.g., an ear of corn and a hat), or…

Professional development (PD) is a potentially important mechanism for enhancing classroom practices and children's learning. In this large-scale randomized controlled trial, we examined the effectiveness of language and literacy PD, with and without coaching, offered at scale to early childhood educators (n = 546) across 1 state. Relative to the…

The transition to kindergarten is foundational for children's future school performance and families' relationships with the educational system. Despite its well-documented benefits, few studies have explored family engagement across the pre-Kindergarten (pre-K) to kindergarten transition nor considered the role of geographic context during this…

Most accountability policies monitor Head Start quality at the center level by selecting a subset of classrooms within a center to represent quality. This study explores variation in classroom quality in Head Start and implications for accountability systems and children's well-being. We find that one third to one half of the variation in quality…

The present study aimed to identify commonalities and points of divergence in the ways that parents, teachers, and administrators characterize children's transition from public pre-K into kindergarten within a large, diverse school district. A wide range of transition practices were in use across the district, including practices designed to…

Students' level of academic skills at school entry are a strong predictor of later academic success, and focusing on improving these skills during the preschool years has been a priority during the past 10 years. Evidence from two prior nationally representative studies indicated that incoming kindergarteners' math and literacy skills were higher…

A child's transition from pre-K to kindergarten is an important time. It builds the foundation for academic, behavioral and social-emotional skills, as well as positive family-school connections, for years to come. Starting kindergarten is also a big shift for many children, one that requires them to adjust rapidly to new routines and…

One of early childhood teachers' first questions of parents with regard to school readiness is whether the child knows the ABCs (Hyson & Tomlinson, 2014). Crucial pre-reading and writing skills, such as oral language, phonological awareness, print awareness, and alphabet letter recognition, are important to children's cognitive development…
