The present study examined the relations between two aspects of peer experiences in preschool classrooms and children's math and literacy development during kindergarten transition. Based on the theoretical framework of classroom ecology model, peer experiences were represented by classroom social network and teachers' grouping preferences. The…

In 2 experiments, I studied the effects of the establishment of Incidental Bidirectional Naming (Inc. BiN) for unfamiliar stimuli on reading comprehension for first-grade students. In Experiment 1, I measured the associations, differences, and predictive value between multiple measures of reading comprehension and Inc. BiN stimulus control in 22…

Measuring and identifying risk for reading difficulties at the kindergarten level is necessary for providing intervention as early as possible. The purpose of this study was to examine concurrent validity evidence of two kindergarten reading screeners, Acadience Reading and Texas Primary Reading Inventory (TPRI), as well as diagnostic accuracy at…

Core reading instruction and interventions have differential effects based on student characteristics such as cognitive ability and pre-intervention skill level. Evidence for differential effect based on affective characteristics is scant and ambiguous; however, students with problem behavior are more often non-responsive to core reading…

Although several studies have shown that planning, attention, simultaneous, and successive (PASS) cognitive processes--operationalized with the cognitive assessment system (CAS; Naglieri & Das, 1997)--are significant predictors of academic performance in the general population, little is known about their role among children with superior…

This research tested a mediation model, examining whether individual differences in mothers' school readiness beliefs influenced home literacy practices and children's later academic achievement among African American (n = 114) and primarily Mexican origin Latina mothers (n = 164) and their children. Mothers of children ages 3-4 years reported…

This study investigated developmental trajectories of reading and math using latent-growth-curve analyses across multiple academic skills, measures, and multiple time periods within a single sample. Reading-related growth was marked by significant individual differences during the early elementary-school period and nonsignificant individual…

Despite the promising future of employment opportunities in occupations related to Science, Technology, Engineering, and Mathematics (STEM), women remain underrepresented in some STEM occupational fields. We use data from the Panel Study of Income Dynamics to study the role of gender differences in achievement and self-perceived ability in math…

Recently, there has been increasing evidence showing that males estimate whole numbers more accurately than females on the number line. However, relatively little is known about what factors contribute to this gender gap. The current study explored potential mediators of the gender difference in number line estimation, including spatial skills and…

The goal of the study was to examine whether target children's temperamental negative emotional expressivity (NEE) and effortful control in the fall of kindergarten predicted academic adjustment in the spring and whether a classmate's NEE and effortful control moderated these relations. Target children's NEE and effortful control were measured in…

The predictive utility of cognitive abilities on reading, writing, and mathematics achievement domains helps inform high-stakes decision making, such as learning disabilities. An examination of differences in specific groups may increase understanding of obtained scores on cognitive ability and academic achievement standardized tests. One…

Reading and math attainment develop during elementary grades. Questions remain, though, about the co-developmental nature of the relation between reading and math. This study examined dynamic, longitudinal pathways between reading and math in first through fourth grades. Participants of the study were 554 academically at-risk children…

This study drew data from a randomized trial of a statewide prekindergarten program in Tennessee and presents new evidence on the impacts of preK on third-grade achievement using administrative data on children's neighborhood environments. Results indicate that preK had no measurable impact on children's third-grade math achievement regardless of…

The purpose of this study was to examine whether components of the Planning, Attention, Simultaneous, and Successive (PASS) processing theory of intelligence predict reading and mathematics proficiency in a group of intellectually gifted children. One hundred forty-two intellectually gifted children (70 females, 72 males; M[subscript…

The present study examined whether global ability influences on reading, writing, and math achievement are generalizable across gender in children and adolescents in Grades 1 to 4 (n = 1,276), 5 to 8 (n = 1,265), and 9 to 12 (n = 1,042) using multiple group structural equation modeling with the standardization samples for the Woodcock-Johnson IV.…
