We evaluate impacts heterogeneity of an Early Childhood Intervention, with respect to the Educational Attainment Polygenic Score (EA4 PGS) constructed from DNA data based on GWAS weights from a European population. We find that the EA4 PGS is predictive of several measures of child development, mother's IQ and, to some extent, educational…

This dissertation investigated whether specific music training components of pitch and rhythm had a differential effect on early literacy skills of phonological awareness, alphabet knowledge, and concept of word awareness. In addition, this study examined associations between musical aptitude and early literacy skills. The central element of this…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of initial variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

"Research Findings:" The influence of early childhood teachers' professional development on fundamental movement skills remains unknown in the literature. The purpose of the present study was to examine how early childhood teachers' professional development in physical education (PE) contributes to predicting children's fundamental…

One year after the COVID-19 quarantine, we conducted an eight-week pilot study with third graders (n = 246), who took a repeating knowledge, attitude, and behavior pretest and a reading comprehension posttest from the eBook for Oral Health Literacy© curriculum. Our research questions were: 1) Will the knowledge, attitude, and behaviors of third…

Supporting socio-economically disadvantaged students to improve their academic resilience is vital in promoting social mobility and halting intergenerational transmission of poverty. Based on the baseline data 2013-2014 from the China Education Panel Survey (CEPS) database, this paper examined the impact of preschool education experience on…

Public preschool boosts academic skills in kindergarten, but little is known about whether that boost lasts to third grade because many studies stop directly assessing children after kindergarten. The current study tests for sustained associations between preschool attendance and an array of repeatedly measured, directly assessed language and math…

To address the needs of a diverse group of students with reading difficulties, a majority of researchers over the last decade have designed and implemented multicomponent reading interventions (MCRIs) that provide instruction in multiple areas of reading yielding mixed results. The current study evaluates whether students' baseline word reading…

We present results from a meta-analysis of 37 experimental and quasi-experimental studies of summer programs in mathematics for children in Grades pre-K-12, examining what resources and characteristics predict stronger student achievement. Children who participated in summer programs that included mathematics activities experienced significantly…

Recess provides an opportunity to promote physical activity among schoolchildren. There is limited research on the effects of specific recess interventions, such as moveable equipment, physical structures, or painting playground, on motivational and affective-emotional variables. The study investigated the impact of a recess intervention based on…

The present study aimed to determine the effect of belief about the consistency of teacher education program in the formation of teacher identity of pre-service primary school teachers. In the study, a correlational survey method was benefitted. The participants of the research study consisted of 203 senior pre-service primary school teachers of…

Introduction: The aim of the study was to describe the teachers' views on the professional development activities, the frequency of the teachers' participation to such activities and effectiveness of these professional development (PD) activities. What's more, it was aimed to analyse the relationship between PD activities that the teachers…

Background/Context: Early childhood education research has consistently found evidence of immediate, positive effects on developmental outcomes. Despite these strong initial benefits, follow-up analyses often reveal that these effects fadeout in the years following participation (e.g., Bailey et al., 2017, Clements et al., 2013; Lipsey et al.…

Research Finding: The present study estimates the long-term effects of Chile's national public Early Childhood Care and Education program (ECCE) on children academic achievement, grade retention and school dropouts, to better understand if ECCE is helping reduce the socioeconomic achievement gap. The present study uses a quasi-experimental design…
