Purpose: Developmental language disorder (DLD) is a lifelong condition that when impacting educational performance is identified and serviced through U.S. schools as outlined in the Individuals with Disabilities Education Act. A few examples of educational categories that refer to DLD are (a) speech or language impairment (S/LI) and (b) specific…

This research synthesizes studies that used a Digitalized Interactive Component (DIC) to assess K-12 student mathematics performance during Computer-based-Assessments (CBAs) in mathematics. A systematic search identified ten studies that categorized existing DICs according to the tools that provided language assistance to students and tools that…

In this meta-analysis, we examined whether children classified with specific language impairment (SLI) experience difficulties with writing. We included studies comparing children with SLI to (a) typically developing peers matched on age (k = 39 studies) and (b) typically developing younger peers with similar language capabilities (k = six…

Background: Outcomes for people with an intellectual disability (ID) may differ depending on the severity of the condition. This study evaluated whether a tool used to screen for the presence of ID could also give an early indication of severity, in order to help inform future support needs. Methods: Multicategory receiver operating characteristic…

Using data from the Special Education Elementary Longitudinal Study (SRI International, 2002), this study estimated reading growth trajectories in a nationally representative sample of 3,421 students with disabilities ages 7 to 17 representing 11 federal disability categories. Reading achievement in all disability categories increased with age,…

This study extends recent findings of a relationship between the relative age of students among their peers and their probability of disability classification. Using three nationally representative surveys spanning 1988-2004 and grades K-10, we find that an additional month of relative age decreases the likelihood of receiving special education…

This is the 32nd Annual Report to Congress on the Implementation of the Individuals with Disabilities Education Act, 2010. Section 664(d) of the Individuals with Disabilities Education Act (IDEA) (P.L. 108-446), as reauthorized in 2004, requires that the Department of Education report annually on the progress made toward the provision of a free…

Some researchers have attributed school learning problems to students entering school too early. Investigated relationship between students' month of birth and learning disabilities, emotional disturbance, and speech and language delays in 1,951 identified students with these disabilities. Analysis did not find that late-birthdate children were…

Fourth- and fifth-grade learning-disabled and nondisabled children were shown cartoon faces and required to learn which faces exemplified criterial attribute (analytic) and family resemblance (holistic) concept category membership. Children performed equally well on criterial attribute tasks, but learning-disabled children did less well on family…

This study investigated taxonomic clustering and use of frequency associations as features in the semantic memory of children (n=30 in grades two and six) with learning disabilities (LD). Results suggested that, when individual child-generated word lists (i.e., meaningful) are used, children with LD may not be impaired in their ability to utilize…

The present research assessed the ability to attend to relevant information in the presence of irrelevant distraction in hyperactive (H), learning disabled (LD), and unselected (US) children. A total of 20 LD, 20 H, and 20 US children divided into younger and older age groups participated in the study. Younger children were between 94 and 104…

Comparison of the free recall of learning-disabled (N=24) and non-disabled (N=24) eight- and ten-year-old readers during directive and nondirective encoding conditions found that both groups recalled more semantically- than nonsemantically-organized items. Learning-disabled readers preferred to encode categorically-organized items nonsemantically…

The differences in performance on a variety of cognitive measures were studied in 67 learning disabled (LD) and normal elementary school children. Younger and older Ss were administered tests of conceptual sorting, central and incidental learning, and selective attention. Teacher ratings of classroom hyperactive behavior were also examined. LD Ss…

Examined racial, gender, intellectual, achievement, and grade-level status of 344 students referred for learning disabilities diagnosis. Found that being white, older, and of higher intelligence and achievement were characteristics of those found ineligible despite severe discrepancy. Being female and less academically able were characteristics of…

Effects of task demands, age, and skill level on memory and metamemory performance were examined for 62 average and 66 low-achieving learning-disabled children. Memory improved with age and skill level, and strategic metamemory revealed age and skill-level differences, but taxonomic metamemory revealed age differences in the average group only.…
