The Reduced Reparameterized Unified Model (Reduced RUM) is a diagnostic classification model for educational assessment that has received considerable attention among psychometricians. However, the computational options for researchers and practitioners who wish to use the Reduced RUM in their work, but do not feel comfortable writing their own…

The extent to which teachers should make use of theoretical and expert knowledge as opposed to tacit experiential knowledge, and how these might be combined, is a perennial issue in discussions on pedagogy. This book addresses these debates through a creative development of the concept of productive uncertainty. Using case studies focusing on…

This study, involving 64 students with specific learning disabilities, found positive correlations between the Wechsler Intelligence Scale for Children-III (WISC-III) and the Arithmetic subtest of the Wide Range Achievement Test-Revised (WRAT-R), the KeyMath-Revised, and the Peabody Picture Vocabulary Test-Revised, but not between the WISC-III and…

This article reviews the efforts made since 1962 to define learning disabilities, discusses 11 prominent definitions, identifies important conceptual elements on which the definitions differ, and calls for a consensual acceptance of the National Joint Committee on Learning Disabilities definition.

This study compared achievement discrepancies for two groups of college students--a randomly selected group of freshmen and a sample of students identified as learning disabled. It found such a considerable overlap in achievement/ability discrepancies between the two groups that such discrepancies could not be considered diagnostic. (Author/DB)

This paper reviewed the psychometric properties of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) criteria for autism. Results indicated that the criteria had, on average, very good sensitivity but much lower specificity. It is concluded that the DSM-III-R criteria act more like screening criteria than diagnostic criteria.…

This paper presents evidence regarding the validity of the diagnostic concept of "autistic-like" childhood disintegrative disorder, also known as Heller syndrome or as disintegrative psychosis. Its inclusion in the DSM-IV (Diagnostic and Statistical Manual) is supported, and proposed criteria and narrative description are provided.…

This study evaluated the voiced/voiceless phonation time for /s/ and /z/ for 11 children (ages 5-10) with vocal pathology and 11 normal speaking children. Results showed no difference in /s/ durations between groups, but /z/ durations and s/z ratios were significantly different. Results are discussed in relation to task construction, instructional…

This study examined whether children (ages 6-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H) could be differentiated from those diagnosed as having attention deficit disorder without hyperactivity (ADD/WO), on an anterior-posterior gradient paradigm. It was predicted that ADD/H children (N=23) would have more deficits…

Explains two microcomputer programs written in BASIC for the Apple IIe microcomputer which allow the user to evaluate the Wechsler Intelligence Scale for Children-Revised and choose recommendations to fit the individual needs of the client being tested. (MBR)

Cluster analysis of data from 166 children with autistic spectrum disorders revealed 4 subtypes with differences in behavioral and cognitive areas. The four subtypes include a typically autistic group, a low-functioning group, a high-functioning group (Asperger syndrome/schizoid), and a hard-to-diagnose group with mild/moderate retardation and a…

This study compared DSM-III-R (Diagnostic and Statistical Manual III, Revised), Childhood Autism Rating Scale, and clinical diagnoses of 138 admissions to a program for diagnosis and treatment of autistic and related communication-handicapped individuals. Results indicated generally high agreement on the diagnosis of autism, with DSM-III-R…

This study sought to extend previous research by investigating performance of intellectucally gifted children on the Mental Processing Composite of the Kaufman Assessment Battery for Children (K-ABC). A sample of 54 children (aged 6-12) referred for possible gifted placement were administered the Sequential and Simultaneous scales. Average scores…

This response argues that Linda Siegel's paper (EC221505) confuses measures of intelligence with predicted achievement, calls for doing away with the construct of learning disabilities rather than the discrepancy definition model, and overlooks the need to determine which students qualify for special educational services for treatment of learning…

This paper provides a history of the development of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) section on pervasive developmental disorders. It describes the process by which the text and criteria for "Autistic Disorder" and "Pervasive Developmental Disorder Not Otherwise Specified" were decided and gives…
