Since the learning disability (LD) population comprises the largest group receiving special education services, there is a need for research to examine the self-concept of this population at a global level. This systematic literature review synthesized 20 years of quantitative research (k = 16) about the self-concept of students with LD. The…

Research on racial and linguistic disparities in disability identification must be grounded on the dual nature of disability as an object of protection and a tool of stratification. This dual nature requires a situated research approach to understand the stratifying power of disability--Who is targeted? Where? How? By whom and to what…

Four studies into characteristics and instructional needs of students with learning disabilities are summarized in this article. These studies are also reviewed in the wider context of mathematics intervention research in special education. These studies generally rely on qualitative methodology, and they are best understood in light of a…

Widely regarded as the standard reference in the field, this comprehensive handbook presents state-of-the-art knowledge about the nature and classification of learning disabilities (LD), their causes, and how individuals with these difficulties can be identified and helped to succeed. Best practices are described for supporting student performance…

Attention-deficit/hyperactivity disorder (ADHD) and learning disabilities (LD) are the most commonly diagnosed childhood disorders, and they frequently co-occur with each other. It has been found that students with comorbidity of ADHD and LD experience more difficulties in school. Even though the research interests in the comorbidity of ADHD and…

Sources of variability in identification of children for learning disabilities include teacher bias, peer tolerance, socioeconomic status, and assessment variability. Implications of these variables for research design and sampling are noted. (CL)

A review of research on the link between learning disabilities and juvenile delinquency notes methodological problems and unanswered questions and cites implications for prevention and intervention both in the schools and the juvenile justice system. (CL)

Analysis of 113 studies revealed that researchers most often selected their learning disabled sample on the bases of academic, age and sex, and intelligence components. Less than half used the process or exclusion components or included a description of grade placement. (CL)

The original authors respond to a critique of their meta-analysis of 94 studies which had failed to support the presence of distinctive Wechsler Intelligence Scale for Children profiles for learning disabled children. The critique contended such a pattern does exist. (Author/DB)

As part of a continuing dialog concerning the validity of a meta-analysis of 94 studies suggesting that there is a lack of any distinctive pattern in the Wechsler Intelligence Scale for Children (Revised) profiles for learning disabled children, this article maintains the view that such differences do exist. (DB)

The study involving 12 to 15 year old boys was designed to provide further information on the question of whether there is a link between adjudicated delinquency and learning disabilities. Ss were given an assessment battery which included three major parts: tests for determining presence or absence of learning disability, an observational…

The authors discussed common approaches used to identify school children with learning difficulties, examined past studies on the prevalence of learning disabled school children, surveyed methodological and conceptual problems in identifying children with learning problems, and presented recommendations for future prevalence studies. Prevalence…

Using strict and lenient mathematics achievement cutoff scores to define a learning disability, respective groups of children who are math disabled (MLD, n = 15) and low achieving (LA, n = 44) were identified. These groups and a group of typically achieving (TA, n = 46) children were administered a battery of mathematical cognition, working…

The data reported here represent the major findings of a number of Institute for Research on Learning Disabilities (IRLD) research studies. The relevant research reports are listed in Appendix A. A summary of the findings is provided in Appendix B. These findings are summarized in two general areas: (a) information on contemporary assessment…

The article presents a brief synthesis of several key conceptual and methodological concerns related to the identification of psychoeducational problems in childhood, along with some ethical perspectives and conclusions regarding the state of the art. (Author)
