Text reading fluency refers to the ability to read connected texts with accuracy, speed, and expression (prosody), and has garnered substantial attention as an important skill for reading comprehension. However, two fundamental questions remain--the dimensionality of text reading fluency including text reading efficiency (accuracy and speed) and…

Children's work habits at school include being a hard worker, turning in work on time, following classroom rules, and putting forward one's best effort. Models on youth character, noncognitive skills, and social-emotional learning suggest that self-management skills like work habits are critical for individuals' subsequent academic success. Using…

This study examines associations between stimulating-responsive social interactions with mothers and nonparental childcare providers during the first 3 years of life and children's vocabulary and mathematics skills through age 15 (N = 1,364). Additive relations were found in which more stimulating-responsive interactions with mothers and with…

Extant literature has established a consistent association between aspects of reading motivation, such as enjoyment and self-perceived ability, and reading achievement, in that more motivated readers are generally more skilled readers. However, the developmental etiology of this relation is yet to be investigated. The present study explores the…

Our newly proposed integrated academic self-concept model integrates 3 major theories of academic self-concept formation and developmental perspectives into a unified conceptual and methodological framework. Relations among math self-concept (MSC), school grades, test scores, and school-level contextual effects over 6 years, from the end of…

Research has documented various family and individual risk factors associated with severe conduct problems, but little is known about the developmental origins of children who engage in both aggressive and prosocial interactions with others. The present study utilized growth-mixture modeling to identify distinct trajectories of physical aggression…

Theory and empirical work suggest inclusion preschool improves the school readiness of young children with special needs, but only 2 studies of the model have used rigorous designs that could identify causality. The present study examined the impacts of the Boston Public prekindergarten program-which combined proven language, literacy, and…

Family processes and parenting practices help explain developmental differences between children in low- versus higher-income households. There are, however, few studies addressing the question of: what are the key family processes and parenting practices for promoting low-income children's growth? We address this question in the present study,…

Using data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (N = 1,364), the present study supports an agentic perspective; it demonstrates that mothers' depressive symptoms in infancy predict children's poor first-grade cognitive functioning because depressive symptoms…

We examined developmental and individual differences in 6th and 8th graders' fraction arithmetic and overall mathematics achievement and related them to differences in understanding of fraction magnitudes, whole number division, executive functioning, and metacognitive judgments within a cross-sectional design. Results indicated that the…
