This study explores the extent to which differences in research design explain variation in Head Start program impacts. We employ meta-analytic techniques to predict effect sizes for cognitive and achievement outcomes as a function of the type and rigor of research design, quality and type of outcome measure, activity level of control group, and…

The issues that prompt this study are based on current research indicating the positive effects of inquiry learning on the cognitive development of children. The purpose of this case study was to understand the effects of inquiry learning on the academic achievement and bilingual verbal ability of 5th grade bilingual students in a French/English…

The current study evaluated the initial efficacy of three intervention programs aimed at improving school readiness in preschool children with externalizing behavior problems (EBP). Participants for this study included 45 preschool children (76% boys; M[subscript age] = 5.16 years; 84% Hispanic/Latino background) with at-risk or clinically…

Background: Our previous investigation showed that infants with cleft lip who had undergone late (three-month) surgical repair (but not those with early, neonatal, repair) had significantly poorer cognitive development at 18 months than a group of unaffected control children. These differences were mediated by the quality of early mother-infant…

The purpose of this study was to determine if the Gearing Up for Kindergarten program created a significant impact on parent understanding of children's development and aspects of school readiness. Parent perceptions of their child's readiness to make the transition to school were also assessed. The study also measured the Gearing Up for…

The federal Early Head Start (EHS) program began in 1995, and a randomized trial was conducted to evaluate the efficacy of 17 EHS programs. In all, 3,001 low-income families (35% African American, 24% Hispanic, and 37% White) with a pregnant women or an infant under the age of 12 months were randomly assigned to a treatment or control group (with…

Preschool attendance is considered an important factor for predicting later success in literacy achievement. This quantitative ex-post facto study examined whether attendance of public prekindergarten is related to improved reading achievement in 2nd grade students in a rural, southeastern school district. The learning theories of Piaget, Bandura,…

Research indicates students who engage in music exhibit improved cognitive development. The quantitative study was conducted in a large suburban school district in Southeast Georgia. This study investigated the impact of music on student achievement when music is incorporated with the core academic subject of mathematics at the elementary level.…

Teaching and learning approaches in ecology very often follow linear conceptions of ecosystems. Empirical studies with an ecological focus consistent with existing syllabi and focusing on cognitive achievement are scarce. Consequently, we concentrated on a classroom unit that offers learning materials and highlights the existing complexity rather…

The focus of this paper centers around timing associated with early childhood education programs and interventions using meta-analytic methods. At any given assessment age, a child's current age equals starting age, plus duration of program, plus years since program ended. Variability in assessment ages across the studies should enable everyone to…

Background: Children ordinarily begin their formal education at the age when the great majority of them are capable of understanding the role of addition and subtraction in changing number. In determining critical differences they can apply the oddity principle--the first "pure" abstraction that children ever develop--understanding that…

Abnormalities in cognition, academic performance and brain volumetrics have been reported in children with chronic epilepsy. The nature and degree to which these problems may be present at epilepsy onset or may instead become more evident over time remains to be determined. This study characterizes neuropsychological status, brain structure and…

This report systematically reviews research on the outcomes of programs that teach young children in a group setting before they begin kindergarten. Study inclusion criteria included the use of randomized or matched control groups, evidence of initial equality, and study duration of at least 12 weeks. Studies included valid measures of language,…

First grade children from two Head Start (HS) groups and one non-Head Start (NHS) group were administered a battery of tests for the purposes of (1) comparing the developmental status of HS and NHS subjects, (2) examing patterns of specific learning disabilities among HS and NHS children, (3) determining the stability coefficients of selected…

This study explored the effects of a full-day preschool program on 4-year-old children. The study compared the development of a group of children (N = 403) who attended the preschool program on a half-day basis during the 1999-2000 school year (the last year the half-day program was in place) with the development of a group of children (N = 418)…
