Classification procedures are common and useful in behavioral, educational, social, and managerial research. Supervised classification techniques such as discriminant function analysis assume training data are perfectly classified when estimating parameters or classifying. In contrast, unsupervised classification techniques such as finite mixture…

An exercise based on images that might shift the balance in favor of students who have superior visual perception and possibly those with language problems and specific learning disabilities, was reviewed. The pictorial format of learning exercise not only increased the students' performance, but also helped students with specific learning…

A pretest-posttest comparison group design was used to investigate the effects of a semantic mapping lesson plus visual display versus a semantic mapping lesson alone on adolescents' with learning disabilities (LD) ability to gain and maintain factual knowledge from expository social studies material. In addition, a posttest only comparison group…

School districts in the U.S. are mandated to identify young children with disabilities. Developmental screeners are typically used to screen for such skill deficits. Academic tests are used in older students. A significant challenge is identifying children with potential learning disabilities early in their school career. This study identifies a…

The purpose of this exploratory study was to analyze the perceptions (through survey data) of Disability Support Services (DSS) personnel regarding the transition process, documentation requirements to receive services, and services for students with invisible disabilities (Autism Spectrum Disorder [ASD], Attention-Deficit Hyperactivity Disorder…

Students with learning disabilities score lower than other at-risk groups on state standardized assessment tests. Educators are searching for intervention strategies to improve math achievement for students with learning disabilities. Using the theoretical framework of behaviorism, the purpose of this quantitative one group pre post test design…

Adolescents who struggle in the area of literacy tend to experience difficulty accessing texts across many different content areas. These students could benefit from increased collaborative interactions between general education content area teachers, special education teachers, and other school personnel with expertise in the area of literacy…

Responsiveness to Intervention (RtI) is recommended both as an essential step before identifying learning disabilities (LD) and as a mechanism for preventing learning difficulties. The use of evidence-based multi-tiered interventions is of critical importance when implementing RtI. This article presents the results of a study that examined the…

The cognitive and behavioral symptoms of nonverbal learning disabilities (NLD) have been described by previous investigators. Nevertheless, we know far less about the potential genetic contributions that may predispose a child to have NLD. An endophenotype model was investigated in 5 samples of children ages 9 to 15 years: NLD (n = 32); reading…

We examined the technical adequacy of writing progress measures as indicators of success on state standards tests. Tenth-grade students wrote for 10 min, marking their samples at 3, 5, and 7 min. Samples were scored for words written, words spelled correctly, and correct and correct minus incorrect word sequences. The number of correct minus…

The benefits of multisensory instruction for teaching mathematics to students in resource rooms were explored. Participants were third and fourth graders (n = 12) in 3 resource rooms for replacement mathematics in a middle-class school district in New Jersey. The students received weekly instruction for several months, using manipulatives and word…

Two major pieces of legislation, the Individuals with Disabilities Education Act (2004) and No Child Left Behind (NCLB) (2001) mandate that students with disabilities be placed in the Least Restrictive Environment and have access to the general education curriculum. To provide access to the general education curriculum, inclusion in general…

The purpose of this study was to provide an evaluation of the undergraduate special education teacher preparation program at King Saud University in Riyadh, Saudi Arabia. A final sample of 160 LD teachers provided the data used for analysis. Data for the study were collected by a survey consisting of five subscales: coursework, internship quality,…

The learning difficulties of 23 adults were investigated in order to determine ways to better serve their literacy needs. These adults were all living in poverty, had less than eighth-grade literacy levels, and had failed to graduate from high school. The participants' records were examined and structured interviews were conducted with them; also,…

The ability of learning disabled children to process, retain, and retrieve verbal information was investigated within a series of information-processing tasks, revealing that both the rate and level at which Ss processed information were below the standards set by normal reading contemporaries.
