This study is a randomized control trial of full- versus half-day prekindergarten (pre-K) in a school district near Denver, Colorado. Four-year-old children were randomly assigned an offer of half-day (4 days/week) or full-day (5 days/week) pre-K that increased class time by 600 hours. The full-day pre-K offer produced substantial, positive…

The purpose of this study was (a) to describe the performance of preschool children from families with college-educated mothers on two norm-referenced measures, the Preschool Language Scale-4 (PLS-4) and Peabody Picture Vocabulary Tests-III (PPVT-III), and (b) to compare the findings with Qi and colleagues who reported PLS and PPVT scores for…

Research Findings: Home language and literacy inputs have been consistently linked with enhanced language and literacy skills among children. Most studies have focused on maternal inputs among monolingual populations. Though the proportion of American children growing up in primarily non-English-speaking homes is growing and the role of fathers in…

Using a large, longitudinal data set that represents 701 state-funded pre-k classrooms and over 2,900 children enrolled in 11 states, the current study examined two hypotheses: (1) children would be perceived to be better adjusted at the beginning of pre-k when rated by a same-race teacher than by a different-race teacher, and (2) children would…

Research Findings: Grounded in the investment model and informed by the integrative theory of the study of minority children, this study used the Early Childhood Longitudinal Study-Birth Cohort data set, a nationally representative sample of young children, to investigate whether the association between socioeconomic status (family income and…

The purpose of this study was to support teachers' child-directed language and student outcomes by enhancing the educative features of an intervention targeted to vocabulary, conceptual development and comprehension. Using a set of design heuristics (Davis & Krajcik, 2005), our goal was to support teachers' professional development within the…

This study examined relations among children's individual experiences, global classroom quality, and school readiness. Preschool children from low-income backgrounds (N = 138; M = 62.16 months; SD = 3.93; range = 55-70) were observed in their early care and education settings, and their language and cognitive skills were assessed. Research…

Why does the United States lag behind so many other countries on international education assessments? The traditional view targets school-based explanations--U.S. schools attract poorer teachers and lack the proper incentives. But the U.S. educational system may also serve children with comparatively greater academic challenges as a result of…

This paper reports on a longitudinal study of significant influences on the cognitive readiness of a group of children, aged 60 to 66 months. All measures were obtained by prospective study, which began with Apgar scores calculated in the delivery room. Subsequent measures were gathered by individual case studies in homes, with children and…

Head Start is a federally funded preschool program for poor children designed to help close the gap between those children and their more advantaged peers before they begin public schooling. Given that Head Start appears to have positive long-run impacts on its recipients, a natural and important next question to ask is: What are the channels…

This study examined associations between quality of social and physical environments in preschools and children's development of academic, language, and literacy skills, and the extent to which preschool quality moderated the associations between child risk and development. Participants were a diverse sample of 540 four-year-old children in…

The culture loaded Peabody Picture Vocabulary Test (PPVT) and the culture reduced Raven's Progressive Matrices (Colored and Standard forms) were examined and compared for large samples of white, black, and Chicano school children, K-8, in three California school districts. On both the PPVT and the Raven's the three ethnic groups show large mean…

This study extends previous research on the social psychological implications of pubertal timing to education by applying a life course framework to data from the National Longitudinal Study of Adolescent Health and from the Adolescent Health and Academic Achievement Study. Early pubertal timing, which has previously been associated with major…

Using data from the same source as that employed in Herrnstein and Murray's book, "The Bell Curve," this study reexamined links between the test scores of mothers and children, paying close attention to what the scores measure and whether these measurements mean the same things for blacks and whites. The study replicated Herrnstein and…

The Head Start Family and Child Experiences Survey (FACES), sponsored by the U.S. Department of Health and Human Services, Administration for Children and Families (ACF), was first launched in 1997 as a periodic longitudinal study of program performance. This report is the fourth in a series that uses data from the FACES 2006 cohort to describe…
