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…

Research Findings: Using a sample of 568 students from 61 kindergarten classrooms whose primary caregivers completed a questionnaire describing their child's early childhood education and care (ECEC) by year from birth to pre-kindergarten, we identified seven pathways characterizing children's ECEC experiences using a latent class analysis. Once…

Adolescent struggling readers (ASRs) with and without disabilities are often reported uniformly in the literature as disengaged from reading and lacking the motivation required to read. The present study tested, at the beginning of the academic year, reader self-perception of sixth grade ASRs (n = 71) enrolled in remedial reading courses using the…

Underperformance in math is a problem with increasing prevalence, complex etiology, and severe repercussions. This study examined the etiological heterogeneity of math performance in a sample of 264 pairs of 12-year-old twins assessed on measures of math achievement, numerosity, and math anxiety. Latent profile analysis indicated 5 groupings of…

To help all students meet the writing expectations of the Common Core State Standards, researchers need a deeper understanding of the characteristics of struggling writers. The purpose of this study was to explore the writing profiles of students including those who have or are at risk for writing disabilities. First-grade students (N = 391) were…

In order to help all students meet the writing expectations of the Common Core State Standards (National Governors Association Center for Best Practices, 2010), researchers need a deeper understanding of the characteristics of struggling writers. The purpose of this study was to explore the profiles of students who may have or be at risk for…

This study examines the genetic and environmental etiology underlying the development of oral language and reading skills, and the relationship between them, over a long period of developmental time spanning middle childhood and adolescence. It focuses particularly on the differential relationship between language and two different aspects of…

Previous research finds that children experience a range of school readiness challenges (e.g., Chartier, Walker, & Naimark, 2010; Zill, 1999). Such challenges vary by children's gender, temperament, and participation in school-based interventions (e.g., Mullola et al., 2011; Bramlett, Scott, Rowell, 2000). However, the examination of child…

A controlled quasi-experimental design was used to evaluate the effects of the use of MindPlay Virtual Reading Coach on participants' reading and spelling achievement. After attrition, participants included 170 students enrolled in eight second-grade classrooms (four classrooms in each school) in two public elementary schools in the southwestern…

Fluency is an essential part of skilled reading that has only recently begun to receive its deserved attention. However, programs that meaningfully engage adult learners in fluency training have not been widely explored in research. In this article, the authors describe an evidence-based adult Guided Repeated Reading program developed for…

There is an ongoing need for literature that identifies the effects of broad contextual risk on school readiness outcomes via family mediating mechanisms. This is especially true amongst diverse and urban samples characterized by variability in immigration history. To address this limitation, family profiles of sociodemographic and contextual risk…

We examined effects of research-based early writing intervention delivered within a data-based instruction (DBI) framework for children with intensive needs. We randomly assigned 46 students with and without disabilities in Grades 1 to 3 within classrooms to either treatment or control. Treatment students received research-based early writing…

This study addresses the current debate about the beneficial effects of text processing software on students with different working memory (WM) during the process of academic writing, especially with regard to the ability to display higher-level conceptual thinking. A total of 54 graduate students (15 male, 39 female) wrote one essay by hand and…
