Students' explanations of their mathematical thinking and conclusions have become a greater part of the assessment landscape in recent years. With a sample of 71 fourth-grade students at risk for mathematics learning disabilities, we investigated the relation between student accuracy in comparing the magnitude of fractions and the quality of…

Student explanations of their mathematical thinking and conclusions have become a greater part of the assessment landscape in recent years. With a sample of 71 4th-grade students at-risk for mathematics learning disabilities, we investigated the relation between student accuracy in comparing the magnitude of fractions and the quality of students'…

The purpose of this analysis was to examine achievement gaps on fractions for very-low-performing students as a function of whether they receive inclusive fraction instruction or specialized fraction intervention and with the shift to Common Core State Standards (CCSS). In three randomized control trials conducted in 3 consecutive years, 203…

The current study utilized data from screening and full evaluations for learning disabilities conducted at a university-based learning center. Results from the screening assessments were analyzed to determine the extent to which they predicted the diagnosis of learning disorders in postsecondary students. Mean scores from the screening assessments…

The literature has long pointed to heightened frequencies of learning disabilities (LD) within the population of law offenders; however, a systematic appraisal of these observations, careful estimation of these frequencies, and investigation of their correlates and causes have been lacking. Here we present data collected from all youth (1,337…

The study was designed to provide a comparison of Peabody Individual Achievement Test (PIAT) and Wide Range Achievement Test (WRAT) scores in 49 learning disabled children (mean age 11 years at initial testing). (SBH)

WISC-R (Wechsler Intelligence Scale in Children-Revised) Verbal and Performance scores were correlated with WRAT-R Wide Range Achievement Test-Revised scores. The verbal score was found to predict reading, spelling, and arithmetic. The performance score did not add significantly to the predictions. Results were consistent with earlier studies.…

Predicted and actual scores on subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Wide Range Achievement Test-Revised (WRAT-R) were obtained from 40 normally achieving postsecondary students (NA) and 92 adult students with learning disabilities (LD). LD students had major deficits in reading-related areas. It was…

Examines differences between 45 learning disabled, mentally retarded, and Title I elementary students on intelligence, academic achievement, and behavior measures. Indicates that such students perform similarly on academic achievement and behavior measures. Learning disabled and Title I students were similar on an intelligence measure; mentally…
