The first purpose of this study was to examine the prevalence of risk for comorbid reading and mathematics disabilities (RMD) at start of first grade, when measured in a representative sample of 3,062 students with first-grade fluency measures (word reading; computation). The second purpose was to examine the utility of these measures for…

The main purpose of this study was to validate the curriculum-based measure "Indicadores de Progreso de Aprendizaje en Matemáticas" (IPAM [Indicators of Basic Early Math Skills]) in a local, Spanish-speaking context. This tool has been designed to identify first-grade students at risk for mathematics learning disabilities. The IPAM…

This study investigated the psychometric properties of the Early Numeracy Screener. The Early Numeracy Screener is a teacher-administered, paper-and-pencil test measuring counting skills, numerical relational skills, and basic arithmetic skills. Three hundred and sixty-six first graders took the Early Numeracy Screener at the beginning of the…

The purpose of this study was to investigate the effect of a morphological awareness intervention on the spelling and writing of second-grade (n = 16) and third-grade (n = 10) students at risk for learning disabilities. The intervention was provided for 25 min per session 4 to 5 times per week for 5 weeks. Students were randomly assigned to the…

Universal screening is a critical component of school-based prevention systems. Screening data enable educators to target students for supplemental intervention, align resources to meet needs, and identify students who may be at risk for learning disabilities. One major requirement of the screening process is that all students are included to gain…

Progressing through schools may be challenging for some students, especially those with learning disabilities (LD). In social studies, for example, students grapple with increasingly complex texts, independent work, direct instruction, critical thinking, analysis, and other learning demands. As students transition from elementary schools where…

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…

In this technical report, implementation strategies from the first two years of Project ICEBERG exploration are described. Over this period of time, a new preschool assessment, curricular activity, and teacher training tool called the Learning Receptiveness Assessment-Greenhouse application, was iteratively developed, refined, and piloted to…

The aim of this study is to examine the effects of computer assisted instruction materials on approximate number skills of students with mathematics learning difficulties. The study was carried out with pretest-posttest quasi experimental method with a single subject. The participants of the study consist of a girl and two boys who attend 3rd…

The development of spelling skill is an intricate process for children with or at risk of Specific Learning Disabilities and requires targeted interventions. This problem exacerbates in the Greek orthographic system owning to its high complexity. The current study presents a novel spelling intervention program for Greek 3rd graders at risk of…

This study used a multiple probe across participants design, replicated across two interventions and counterbalanced across participant groups to examine the effects of number sense intervention and extensive practice intervention on strategy transformation when students with mathematics learning disabilities (MLD) solved basic fact problems. In…

The main goal of the present study was to shed further light on the psychological characteristics of children with different learning disability profiles aged between 8 and 11 years, attending from third to sixth grade. Specifically, children with nonverbal learning disabilities (NLD), reading disabilities (RD), or a typical development (TD) were…

This study reports the psychometric properties of a Basic Number Processing Test (BNPT), which was developed in order to determine elementary school students at risk for Mathematical learning disorder. A total of 478 primary school students were selected from 12 different public schools with an attempt to get a representative sample. The…

Response to Intervention (RTI) has been used in the public school system to improve student achievement in areas of weakness and identify students who may need further resources. The local goal is to improve the retention rate and identify those students that may need additional support systems. The overall goal is to decrease the number of…

This study aimed to explore the spatial numerical association of response codes (SNARC), the flanker, and the numerical distance effects in children with mathematical difficulties. From a sample of 720 third, fourth, and fifth graders, 60 children were selected and divided into the following three groups: typically developing children (TD; n =…
