Purpose: Using data from 1,868 children from the US, Australia, and Sweden who took a 10-word spelling test in kindergarten and a standardized spelling test in Grades 1, 2, and (except for the Australian children) Grade 4, we examined two questions. First, does the quality of a child's errors on the kindergarten test help predict later spelling…

There is a virtual consensus regarding the types of language processes, interactions, and material supports that are central for young children to become proficient readers and writers (Shanahan et al., 2008). In this study, we examine these supports in both home and school contexts during children's critical transitional kindergarten year.…

Across multiple schools and sites, the impact of grade-at-intervention was evaluated for children at risk or meeting criteria for reading disabilities. A multiple-component reading intervention with demonstrated efficacy was offered to small groups of children in 1st, 2nd, or 3rd grade. In a quasi-experimental design, 172 children received the…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

More than 20?years ago, Minshew and colleagues proposed the Complex Information Processing model of autism in which the impairment is characterized as a generalized deficit involving multiple modalities and cognitive domains that depend on distributed cortical systems responsible for higher order abilities. Subsequent behavioral work revealed a…

In a sample of 50 verbally fluent adolescents and adults with autism spectrum disorders (age: 16-31 years; verbal IQ: 72-140), we examined the pattern of response and associations between scores on common measures of depressive symptoms, participant characteristics, and clinical diagnosis of depressive disorders. Beck Depression Inventory--Second…

Computers have taken an increasingly prominent role in education around the world in recent years in developed and developing countries alike. As developing country governments have turned their focus from increasing enrollment to improving the quality of education in their schools, many have made access to computers a key component to their…

The purposes of this study were to investigate the reliability and construct validity of measures of reading component skills with a sample of adult basic education (ABE) learners, including both native and nonnative English speakers, and to describe the performance of those learners on the measures. Investigation of measures of reading components…

Objective: To characterize the late adolescent and young adult outcomes of girls diagnosed with ADHD in childhood. Method: The study included 58 women from a larger longitudinal study of ADHD. A total of 34 (M = 19.97 years old) met "DSM" criteria for ADHD in childhood, whereas the remaining 24 (M = 19.83 years old) did not. Self- and…

Elementary school students often misinterpret the equal sign (=) as an operational rather than a relational symbol. Such misunderstanding is problematic because solving equations with missing numbers may be important for the development of higher order mathematics skills, including solving word problems. Research indicates equal-sign instruction…

National estimates of school achievement as measured by the reading and arithmetic subtests of the Wide Range Achievement Test (WRAT) for the noninstitutionalized population of the United States aged 12-17 years are presented. Data were obtained in the Health Examination Survey (HES) of 1966-70. In the survey a probability sample of 7,514 youths…

Compared regression lines for prediction of Wide Range Achievement Test scores by Wechsler Intelligence Scale for Children and revised WISC Full Scale IQs across race. Results support the use of a common regression line in the prediction of achievement scores for races. (Author)

Compares performances on the Peabody Individual Achievement Test (PIAT) Math, Spelling, and Reading subtests with the Wide Range Achievement Test (WRAT) Arithmetic, Spelling, and Reading subtests for a sample of fourth-graders. Nearly all PIAT-WRAT intercorrelations were positive and significant, and highest for the similarly labelled subtests.…

To determine if different graded word lists can be used interchangeably for assessment purposes, and to determine if age, grade, or sex affects performance on the different graded word lists, a study examined the Wide Range Achievement Test (WRAT), Levels I and II, the San Diego Quick Assessment, and the Graded Word Reading Test by F.J. Schonell.…
