(1) Background: The response to intervention (RtI) model makes possible the early detection of reading problems and early intervention for students at risk. The purpose of this study is to analyze the effective measures that identify struggling readers and the most effective practices of the RtI model in reading in Primary Education. (2) Method: A…

We examined the effect of intervention dosage on mathematics outcomes for students with or at risk for mathematics learning disability in kindergarten through third grade. Using linear and nonlinear models, we meta-analyzed 164 effect sizes from 24 published experimental and quasi-experimental studies. Results supported a linear model and an…

A meta-analysis of single-case design research was conducted to evaluate the effectiveness of mathematics interventions for elementary grade (K-5) students with mathematics difficulties (MD) and mathematics learning disabilities (LD). The study examined whether intervention effectiveness varied as a function of participant characteristics (i.e.,…

Spatial language and ability play important roles in children's cognitive development. Spatial ability in kindergarten predicts achievement in reading, math, science, and technology in primary school and therefore constitutes an important skill set in preparation for school entrance. Good spatial thinking skills are required for learning in…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Fewer than half of students demonstrated proficiency on Michigan state-administered summative assessments at the end of third grade at a rural, Title I school in Michigan. The purpose of this quantitative study was to compare reading fluency gains between grade levels (i.e., kindergarten, first, and second grades) in an effort to better understand…

The majority of research on the relationship between phonological awareness and written language focuses on demonstrating the influence of the former on the latter. However, the aim of this study is to analyse the effects of an Early Years written language programme on phonological awareness. The sample comprises 56 Spanish children aged 5-7 who…

The aim of the study was to examine the effect of an activity with an educational electronic storybook with math content on the emergent math of kindergarteners at risk for learning disabilities (LD) compared with kindergarteners with typical development (TD). The study included 107 kindergarteners aged 4.6 to 7. Both the participants at risk for…

This paper reviews findings from four research syntheses that report the effects of academic language and/or reading interventions on language and reading outcomes for English learners who have or are at risk for learning difficulties. Studies included in the syntheses varied in research design and addressed multiple areas of reading and language.…

We review the evolution of the conceptualisation of dyslexia and along with it the current, 21st century definition of dyslexia. Our starting point is the seminal report by Pringle Morgan in 1896, followed by early 20th century reports by Hinshelwood, and continuing with concepts of brain injury and minimal brain dysfunctions then to the emergence…

Teachers' implementation of differentiated supplemental instruction is critical to help students with or at risk for reading-related disabilities acquire early reading and vocabulary skills. This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading…

We use administrative data to measure whether attending a charter school in Denver, Colorado, reduces the likelihood that students are newly classified as having a disability in primary grades. We employ an observational approach that takes advantage of Denver's Common Enrollment System, which allows us to observe each school that the student…

Spelling is one of the most challenging areas for students with learning disabilities (LD), and improving spelling outcomes for these students is of high importance. In this synthesis, we examined the effects of spelling and reading interventions on spelling outcomes for students with LD in Grades K through 12. A systematic search of peer-reviewed…

Articles in this issue examine (1) the primary sources of variability in reading and language achievement among Spanish-speaking English learners (ELs) in the United States, (2) the extent to which poor performance at the end of grade 2 is identifiable in developmental trajectories beginning in kindergarten, (3) the relations among core reading…

We analyzed two nationally representative, longitudinal data sets of U.S. children to identify risk factors for persistent mathematics difficulties (PMD). Results indicated that children from low socioeconomic households are at elevated risk of PMD at 48 and 60 months of age, as are children with cognitive delays, identified developmental delays…
