Various factors at the individual and school levels contribute to the impairment of academic achievement. We examined whether academic class composition, measured as average class achievement and class heterogeneity (variance in achievement within class), moderates the associations of inattentiveness and hyperactivity/impulsivity with academic…

The present study employed a difference-in-difference approach to determine the impact of a technologically enhanced diagnostic and formative assessment system implemented in one US state in kindergarten through third grade on school-level end-of-year third-grade reading test scores and percentage of students receiving special education services.…

Classroom reading instruction is the foundation of Multi-Tiered Systems of Support in Reading (MTSS-R) and the focus of many state reading reforms, initiatives, and policies. The purpose of this study was to evaluate whether comprehensive and coordinated Tier 1 core reading instruction was associated with higher early reading outcomes of students…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Literacy is essential to the development of any nation. Despite foreign aid to support education initiatives in Africa, high rates of illiteracy persist. This synthesis examined the extent to which early literacy intervention research has been conducted in Africa and the effects of these interventions on reading outcomes for students in…

Texts classified according to guided reading levels (GRL) are ubiquitous in US beginning reading classrooms. This study examined features of texts across three grade bands (kindergarten, early first grade, final first grade) and the 10 GRLs within these bands. The 510 texts came from three programs with different functions in beginning reading…

Research suggests that elementary school absenteeism can contribute to deficits in achievement. It is less clear how the timing and growth in rates of attendance shape early elementary school achievement. The present study examined the role of absenteeism in pre-K and early elementary school in the context of third-grade achievement, along with…

A mixed-design study investigated how teachers and second/third- and fourth-grade bilingual students in three high-poverty schools responded to dialogic cognitive strategy instruction or dialogic responsive engagement (RE) instruction compared with a treated control (vocabulary). The second graders were taught in Spanish, and the fourth graders…

Piecewise growth models (PGMs) were used to estimate and model changes in the preliteracy skill development of kindergartners in a moderately sized school district in the Pacific Northwest. PGMs were applied to interrupted time-series (ITS) data that arose within the context of a response-to-intervention (RtI) instructional framework. During the…

This study reports the results of a cluster RCT evaluating the impact of Enhanced Core Reading Instruction on reading achievement of grade 1 at-risk readers. Forty-four elementary schools, blocked by district, were randomly assigned to condition. In both conditions, at-risk readers received 90 minutes of whole-group instruction (Tier 1) plus an…

A one-group repeated-treatment design was used to examine the academic year and summer oral reading fluency outcomes for students attending a district-sponsored summer literacy program (N = 250). Piecewise growth models applied to longitudinal data obtained during the first and second grade and over the course of the intervening summer revealed…

The authors investigated the differential effect of retention on the development of academic achievement from grades 1 to 5 on children retained in grade 1 over 6 years. Growth mixture model (GMM) analyses supported the existence of two distinct trajectory groups of retained children for both reading and math among 125 ethnically and…

Experiential education is a child-centered educational framework that is popular in Flemish kindergartens. In this study, the impact of five experiential practices (autonomy support, stimulation, emotional support, time for choice activities, and interest-based activities) and the moderating influence of initial achievement (language and…

To reach the national goal that all children in the United States will read at an appropriate level by the end of third grade, the Center for the Improvement of Early Reading Achievement (CIERA) has studied the reading growth of children in preschool and primary classes, both in and out of school. Our framework suggests that children need to…
