Recent findings that earlier fraction knowledge predicts later mathematics achievement raise the question of what predicts later fraction knowledge. Analyses of longitudinal data indicated that whole number magnitude knowledge in first grade predicted knowledge of fraction magnitudes in middle school, controlling for whole number arithmetic…

Educators and policymakers are paying increased attention to the academic outcomes of students in the middle grades (i.e., Grades 6-8). One reform proposed to improve outcomes for these students is to replace middle schools (with Grade 6-8, 7-8, or 7-9 configurations) with K-8 schools. This longitudinal study evaluated the effects of continuously…

This study makes two contributions to the literature. First, it bridges the sociological discussion of social class habitus with psychological notions of adolescents' educational expectations, locus of control, and self-concepts. Second, it empirically examines the relationships between early employed parental practices and expectations and…

Recent studies have used increasingly complex methodologies to estimate the effect of peer characteristics--race, poverty, and ability--on student achievement. A paper by Hanushek, Kain, and Rivkin using Texas state testing data has received particularly wide attention because it found a large negative effect of school percent black on black math…

The current study examines the social and behavioral development of school-age children with different histories of overweight onset. Eight thousand children from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K) participated. Three groups of children were identified for analysis: (1) those who were persistently overweight from…

Multinomial stepwise logistic regression analyses were used to establish the most robust set of risk factors that would best predict low basic reading skills (i.e., a standard score less than 85 on the Woodcock Reading Mastery Test-Revised Basic Reading Skills cluster) of kindergarten and first-grade children at risk for emotional and behavioral…

Facing mounting evidence that California has fallen behind on many key indicators of educational performance, policymakers and the public share considerable interest in exploring whether California should expand public funding for preschool education. This expanded funding will be most effective if resources can be directed to their most efficient…
