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.…

A better understanding of factors influencing who receives disability support services through an Individualized Education Program (IEP) or a Section 504 Accommodation Plan from the Rehabilitation Act of 1973 (504 plan) and when is needed. This study used administrative data from11,405 students enrolled in 121 Baltimore City Schools (51% male; 85%…

This study investigated the relationship between non-cognitive factors (mathematics anxiety, Emotional Intelligence, and mathematics self-concept) and mathematics performance in students with and without Mathematics Learning Disability (MLD). Participants were 340 3rd, 4th, and 5th grade students from a public elementary school. Results showed…

Facility with learning from multiple text documents is critical for college and career readiness. However, children with reading difficulties and disabilities have been largely excluded from research on multiple document comprehension. Accordingly, little is known about how children with reading difficulties and disabilities perform on…

This study examined the relationships between word reading and rapid automatized naming (RAN) for objects and letters in Arabic-speaking children with and without dyslexia to determine potential modulating effects of color on naming by comparing children's performance on color and black-white RAN plates. Participants were 114 Arabic-speaking third…

A number of previous studies have identified cognitive deficits in developmental dyscalculia (DD). Yet, most of these studies were in alphabetic languages, whereas few of them examined Chinese DD. Here, we conducted a study aiming to determine the cognitive factors associated with DD in Chinese children. Five candidate cognitive factors of…

The problem of disproportionality in special education is complex and requires an investigation of multiple factors related to racial, ethnic, linguistic, and socioeconomic backgrounds, school context, and family characteristics. Researchers have debated whether language minority (LM) students are under or overrepresented in special education, but…

Little is known about the mathematical development of students with intellectual disabilities (ID) in inclusive classrooms. It is important to have a research-based understanding of the subject since inclusive education is becoming the norm in many countries, and an increasing number of students with an ID now attend mainstream schools. We…

This paper aims to investigate the clock reading skills of third graders with and without dyscalculia risk. Data were collected from 290 (136 girls, 154 boys) third graders from three different primary schools located in the city center of Mus. Of the participants, 29 were at risk of dyscalculia while 261 were normally achieving. The study…

We analyzed a population-based cohort of 11,780 U.S. children to identify risk and protective factors by kindergarten predictive of being frequently verbally, social, reputationally, or physically victimized during the upper elementary grades. We also stratified the analyses by biological sex. Kindergarten children displaying externalizing problem…

Written-expression curriculum-based measurement (WE-CBM) is used for screening and progress monitoring students with or at risk of learning disabilities (LD) for academic supports; however, WE-CBM has limitations in technical adequacy, construct representation, and scoring feasibility as grade-level increases. The purpose of this study was to…

The purpose of this study was to explore the relationships among (1) special education teachers' knowledge for teaching reading fluency, (2) the specific instructional practices they used in fluency instruction, and (3) gains of students with specific learning disabilities (SLD) on a performance measure of oral reading fluency (ORF). Analyses…

Students with early indicators of behavior risk have predictable, negative outcomes, and those with co-existing academic problems have significantly more negative outcomes. Identifying academic subclasses of students with behavior risk can inform integrated interventions and school-based problem-solving teams. In addition, identifying academic…

The goal of the present article is to synthesize findings to date from the Delaware Longitudinal Study of Fraction Learning. The study followed a large cohort of children (N = 536) between Grades 3 and 6. The findings showed that many students, especially those with diagnosed learning disabilities, made minimal growth in fraction knowledge and…
