The importance of fraction knowledge to later mathematics achievement, along with U.S. students' poor knowledge of fraction concepts and procedures, has prompted research on the development of fraction learning. In the present study, participants' (N = 536) development of fraction magnitude understanding and fraction arithmetic skills was assessed…

WISC and WISC-R test results were correlated with achievement test scores and school grades of 36 children who had completed two years of school. Global intelligence estimates from both scales correlated at significant levels with all achievement test measures. (Author)

Children (N=30) ages 6-10 were selected who had been referred for psychological evaluation from the public schools. WISC-R was significantly lower than WISC FS IQ's and similar to S-B L&M IQ's. The use of the WISC-R over the WISC will result in greater numbers of children being classified as retarded. (Author)

Investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test using the factor scores of the Wechsler Intelligence Scale for Children-Revised as potential predictors. Results indicated that the freedom from distractibility factor score significantly aided in the prediction of reading and spelling…

The Brain Wave Analyzer (BWA Ertl 02) was used to measure the brain potentials of 110 public school children. Resulting scores were correlated with concurrent measures of school achievement. Results indicate that certain brain wave scores have relatively low correlations with school achievement compared to traditional intelligence measures but may…

Fifty-eight middle class children were tested over 6 years with 25 achievement, I.Q., and personality tests. Consistency of test results were evaluated by a variance comparison method and a simple signal detection model. Both methods lead to the conclusion that achievement tests are far better predictors than personality tests with I.Q. scales…

This study is concerned with the manner in which experience with concrete, quantitative, interpersonal, and verbal content influences the development of ability patterns in first grade children. The literature related to theoretical models of intellectual development indicates that abilities develop in response to experiential variables, such as…

The relative predictive abilities of two indices of test anxiety were investigated. The galvanic skin response (GSR) and the Test Anxiety Scale for Children (TASC) were used as predictor variables for IQ and achievement test performance. The results of multiple linear regression analysis indicated that neither the TASC nor the GSR, combined over…

The Wechsler Intelligence Scale for Children-Revised (WISC-R) and Kaufman Assessment Battery for Children (K-ABC) were used to predict achievement (measured by the Stanford Achievement Test) for 200 students with mild handicaps, in grades K through 6 in a rural western school district. Males scored significantly higher than females for every…

The tetrad of subtests of the Wechsler Intelligence Scale for Children-Revised (WISC-R) that best predicts the WISC-R Full-Scale intelligence quotient (IQ) was determined for 1,589 Appalachian students referred for evaluation in grades 1-4, 5-8, and 9-10. The sample was divided into three groups. Students in grades 1 through 4 (n=655) were those…

Thirty bilingual Hispanoamerican students between the ages of eight and thirteen were given verbal and non-verbal intelligence tests which were then correlated with overall school grade point average. Non-verbal tests resulted in higher correlations; the Raven Colored Progressive Matrices appeared to be the best predictor of school successes of…

Multivariate statistical analysis determined relationships between scores on the Otis-Lennon School Ability Test and the Stanford Achievement Test at grades 2, 4, and 6 for 272 students. The best predictor of achievement at a later grade was achievement at an earlier grade. Implications are discussed. (SLD)

The stability of the Kaufman Assessment Battery for Children (K-ABC) was studied by examining its performance over a 5-year interval with 16 non-handicapped children aged 45 to 61 months at the beginning of the study. Global scale stability coefficients (corrected for restriction in range) for Time 1 testing (age 4 years) and Time 4 testing (age 9…
