This study was designed to experimentally examine how supplemental vocabulary instruction provided in either whole-group or small-group settings influences low-income preschoolers' word knowledge and conceptualdevelopment. Using a within-subject design, 108 preschool children from 12 Head Start classrooms participated in an 8-week intervention,…

The Arnold Arboretum is a public "tree museum" that sits on more than 300 acres of parkland in Boston. Like many public parks, the arboretum uses a percentage of its funding to provide nature education for adults and schoolchildren, facilitated by trained volunteer docents. One such effort is the Head Start-Arboretum project, which…

This paper estimates future adult earnings effects associated with a universal pre-K program in Tulsa, Oklahoma. These informed projections help to compensate for the lack of long-term data on universal pre-K programs, while using metrics that relate test scores to valued social benefits. Combining test-score data from the fall of 2006 and recent…

Superhero play has long been thought of as violent, aggressive, and disruptive. Some argue that aggressive play should not be allowed because it exposes children to inappropriate concepts and attitudes and sends the message that the use of aggression can achieve a desired goal. However, educators know that pretend play is an avenue for healthy…

Research Findings: The purpose of this study was to examine whether approaches to learning significantly mediated relations between cognitive flexibility (a component of executive functions) and school readiness in Head Start preschoolers. A total of 191 children from 22 Head Start classrooms were directly assessed on cognitive flexibility and…

Recently, research has begun to identify cognitive and social-emotional predictors of early academic success. Yet few studies have examined the mechanisms by which children's social-emotional skills are associated with later academic success. The present study examines the associations between preschool emotion knowledge, kindergarten attention…

The school-readiness gap for Latino dual language learners in the United States has been well documented, despite a strong research base highlighting effective strategies and practices for supporting their academic success. However, current educational practices reflect the hegemonic discourse that, because the United States is an English-speaking…

The objective of this study was to evaluate two early intervention packages to promote successful transitions to kindergarten for preschoolers with behavior problems recruited from Head Start preschools. Fifty children (M[subscript age] = 61 months; 76% male; 98% minority) referred by teachers due to early externalizing behavior problems were…

There is growing evidence among researchers and international organisations that quality of Early Childhood Education and Care (ECEC), and ultimately the outcomes for children and families--especially disadvantaged ones--is dependent on well-educated and competent staff, and that a lack of higher pre-service training can be partly compensated by…

Research Findings: This study compared the effects of content-based shared book-reading instruction versus an explicit vocabulary-only condition on the vocabulary development of preschool dual language learners (DLLs). Using shared book reading as the mode of instruction, we randomly assigned 48 bilingual preschool teachers and 281…

The Obama Administration's most recent regulation on designation renewal of Early/Head Start grantees opens opportunities for early childhood programs in some communities to compete with existing grantees for the federal funding. Understanding some of the behind-the-scenes work that goes into Head Start may be helpful to centers deciding whether…

The last several decades have seen growing global interest in the potential for public investments in early childhood care and education (ECCE) to improve the development of young children, especially those from socially disadvantaged groups. This interest is based on evidence of the importance of environmental influences on early cognitive and…

The purpose of this study was to describe the physical activity levels of urban inner city preschoolers while attending Head Start, the federally funded preschool program for children from low-income families. Participants were 158 African American children. Their physical activity during Head Start days was measured using programmed RT-3…

Preschool is a crucial time for obesity prevention, as children are developing eating and physical activity habits. A lack of physical activity at preschool may contribute more to overweight children than parental influences such as modeling and supporting physical activity or providing fitness equipment in the home. Let Me Play is a comprehensive…

Research Findings: The purpose of this paper is to explore the association between maternal reading beliefs and children's emergent literacy outcomes in light of maternal education. Furthermore, I consider whether maternal reading beliefs may mediate the association between maternal education level and children's print knowledge and phonological…
