A comparison of the reading performance of 30 second-graders with learning disabilities and 30 controls found all but three of 10 subtests of the Woodcock Diagnostic Reading Battery produced significant differences between groups. The three subtests that did not reach significance were Oral Vocabulary, Listening Comprehension, and Memory for…

This article argues that the regression-based discrepancy method used in the diagnosis of learning disabilities is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. It is mathematically demonstrated that the regression-based discrepancy method largely reflects…

This article evaluates conclusions in Van den Broeck's article (2002) that argue the regression-based discrepancy method (RDM) used in learning disabilities diagnosis is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. It concludes acceptable models support the…

This article responds to a critique by Willson and Reynolds (2002) that argued for the use of the regression-based discrepancy method (RDM) for identifying learning disabilities. It argues the statistical and theoretical counterarguments are based on a misreading of the statistical models presented. (Contains 8 references.) (Author/CR)

Discusses the difficulty in validating central auditory processing disorder (CAPD) as a diagnostic label in school-aged children, and examines the extent to which reading, language, and attention disorders in school-aged children involve perceptual dysfunctions limited to a single sensory modality. Multimodal perceptual testing for diagnosis is…

This investigation reports average length of communication units (C-units) in words and in morphemes for 95 African-American boys and girls (ages 4-6) from lower-income, urban homes. Mean C-units increased across the age span and syntactic complexity of the children's language samples correlated positively with increases in C-unit length.…

This article examines the legal requirements of assessing students with disabilities, especially students with emotional and behavioral disorders (EBD). It reviews assessment legislation and litigation in special education and explains specific requirements for assessing students with EBD. The article also examines school districts' obligations…

Responding to disruptive or troubled pupils with emotional and behavioural difficulties (EBD) remains a highly topical issue. The challenges these children present relate to wider issues of continuing political concern: the perceived declining discipline in schools; school and social exclusion; the limits to inclusion for children with special…

This report describes a project in Utah to investigate the feasibility of using transient evoked otoacoustic emissions (TEOAE) as a tool for screening for hearing loss in children with developmental disabilities (DD). Study participants included 336 students (ages 5 to 7) with no identified DD and 765 students (ages 3 to 7) with one or more DD.…

Syntactic development in the oral language of learning disabled and normal students at two intermediate and two secondary-school age levels was compared using two indices, the T-unit and the Syntactic Density Score. It was concluded that no single, sensitive, numerical index exists to quantify syntactic development. (SW)

This paper proposes an approach to diagnosing learning disabilities that measures the intrinsic processing or capacity weaknesses that are presumed to underlie academic performance problems. This approach is contrasted with the "diagnosis by exclusion" method currently used. The paper discusses: (1) a definition of intrinsic processes with…

The 16 chapters of this comprehensive guide to teaching students with learning disabilities cover the following topics: (1) an overview of the field of learning disabilities (characteristics, causes, prevalence, prognosis, and resources); (2) research in the field of learning disabilities (how the brain works, how children learn); (3) relevant…

This report discusses the outcomes of a study of 147 children (ages 7-10) with learning disabilities that investigated the extent to which students legally classified with learning disabilities concurrently manifested mixed lateral dominance (MLD). The study was conducted to determine if MLD was a possible predictive factor for early…

This guide from Iowa is intended to: clarify changes in the state's new rules on special education; make the state's definition of mental disability operational; provide practical guidelines on preferred practices for determination of mental disability and the need for special education services; and highlight prescriptive assessment practices…

This manual, the 10th edition of a regularly published definition and classification work on mental retardation, presents five key assumptions upon which the definition of mental retardation is based and a theoretical model of five essential dimensions that explain mental retardation and how to use the companion system. These dimensions include…
