Within the United States, there are a variety of early education models and curricula aimed at promoting young children's pre-academic, social, and behavioral skills. This study, using data from the Miami School Readiness Project (Winsler et al., 2008, 2012), examined the school readiness gains of low-income Latino (n = 7,045) and Black (n =…

Phoneme awareness, letter knowledge, and rapid automatized naming (RAN) are well-known kindergarten predictors of later word recognition skills, but it is not clear whether they predict developments in accuracy or speed, or both. The present longitudinal study of 172 Danish beginning readers found that speed of word recognition mainly developed…

The primary aim of this group randomized trial was to test the efficacy of INSIGHTS Into Children's Temperament (INSIGHTS) in increasing the academic achievement and sustained attention and reducing the disruptive behavior problems of low-income kindergarten and 1st grade children. Twenty-two urban elementary schools serving low-income…

The focus of this study was connections among 3 aspects of mathematical cognition at 2nd grade: calculations, word problems, and prealgebraic knowledge. We extended the literature, which is dominated by correlational work, by examining whether intervention conducted on calculations or word problems contributes to improved performance in the other…

The use of manipulatives to teach mathematics is often prescribed as an efficacious teaching strategy. To examine the empirical evidence regarding the use of manipulatives during mathematics instruction, we conducted a systematic search of the literature. This search identified 55 studies that compared instruction with manipulatives to a control…

Background: The sequencing of learning materials greatly influences the knowledge that learners construct. Recently, learning theorists have focused on the sequencing of instruction in relation to solving related problems. The general consensus suggests explicit instruction should be provided; however, when to provide instruction remains unclear.…

Background: The role of reactive aggression in the development of peer victimization remains unclear due in part to a failure to account for confounding problems of behavioural undercontrol (e.g., hyperactivity). As well, the school social context has rarely been examined to see whether these risks are mediated by relationships with teachers.…

Background: Math learning is a complex process that entails a wide range of cognitive abilities to be fulfilled. There is sufficient evidence that both general and specific cognitive skills assume a fundamental role, despite the absence of shared consensus about the relative extent of their involvement. Moreover, regarding general abilities, there…

This study is a population-based investigation of children's school readiness with a national sample of low-income children, utilizing data from the Family and Children's Experiences Survey (FACES; 2000-2003). Guided by a developmental ecological framework, we posed 3 research questions: (a) How do children's early school readiness skills in the…

In a randomized control trial, the authors tested whether short- and long-term effects of an early literacy intervention are moderated by mild perinatal adversities in accordance with differential susceptibility theory. One-hundred 5-year-old children (58% male) who scored at or below the 30th percentile on early literacy measures were randomized…

The goal of this study was to examine how different types of social experiences in kindergarten relate to Grade 1 academic achievement, while controlling for possible genetic and shared environmental influences through the use of the monozygotic (MZ) twin difference method. Social experiences in kindergarten included relationship quality with the…

Classmates' academic skill level (peer effects) is emerging as an important predictor of individual student achievement, particularly in the early grades. However, less is known about the influence of peer effects with regard to classmates' self-regulation skills and whether they are associated with students' academic gains. Examining this is the…

We examined whether a theoretically based number board game could be translated into a practical classroom activity that improves Head Start children's numerical knowledge. Playing the number board game as a small group learning activity promoted low-income children's number line estimation, magnitude comparison, numeral identification, and…

This experiment tested the hypothesis that organizing arithmetic fact practice by equivalent values facilitates children's understanding of math equivalence. Children (M age = 8 years 6 months, N = 104) were randomly assigned to 1 of 3 practice conditions: (a) equivalent values, in which problems were grouped by equivalent sums (e.g., 3 + 4 = 7, 2…

The current study follows a sample of lower skilled language minority (LM) and native English-speaking (non-LM) students who participated in an efficacy trial of a kindergarten phonics-based intervention. Follow-up procedures allowed 93% of the original sample to be retained for simple treatment effects modeling (N = 78 LM and N = 59 non-LM) and…
