This study looked at the effect of both quantity and quality of computer use on achievement. The Program for International Student Assessment (PISA) 2003 student survey comprising of 4,356 students (boys, n = 2,129; girls, n = 2,227) was used to predict academic achievement from quantity and quality of computer use while controlling for…

We develop a model of induced innovation that applies to medical research. Our model yields three empirical predictions. First, initial death rates and subsequent research effort should be positively correlated. Second, research effort should be associated with more rapid mortality declines. Third, as a byproduct of targeting the most common…

Data on the concurrent validity of the McCarthy Scales, using two Wechsler Scales for Children as criteria, were compared with those of previous studies. Significant moderate to strong correlations at preschool and school-age levels between the General Cognitive Index of the McCarthy and Wechsler IQ's were noted. (Author/RD)

External correlates of Minnesota Multiphasic Personality Inventory (MMPI) profile scales were investigated in a racially mixed urban sample of 247 adolescent psychiatric inpatients and outpatients (140 males and 107 females). Correlates included items completed by the patients' mothers. Gender plays a role as moderator of scale interpretation…

A public school district in Alabama uses the Otis Lennon School Ability Test (OLSAT) in place of the Wechsler Intelligence Scale for Children (Revised) (WISC-R) as a screening device for students who are referred for possible special education placement. To determine the relationship between the two tests, Pearson product moment correlation…

Perinatal variables were used to predict 7-year outcome for 538 children, 32% Negro and 68% white. Mother's age, birthplace, education, occupation, marital status, neuropsychiatric status, family income, number supported, birth weight, one- and five-minute Apgar scores were regressed on 7-year Verbal, Performance and Full Scale IQ, Bender, Wide…

Interrelationships among IQ, academic achievement, and teacher ratings of pupils' classroom achievement were evaluated in a large sample of children from various racial and socioeconomic backgrounds. A substantial relationship between standardized measures of IQ and achievement was found and was independent of race, but decreased with increasing…

Correlation, regression, and score interval analyses were conducted for academic tests including the Scholastic Aptitude Test (SAT), Test of Standard Written English (TSWE), and four subtests of the English Placement Test (EPT) for six different groups. The groups were men, women, Asians, blacks, Hispanics, and whites. The use of grade point…

Background: The overall goal of the No Child Left Behind Act (NCLB) of 2001 is to close, by the end of the 2013-2014 academic year, "the achievement gap between high- and low- performing students, especially the achievement gap between minority and non-minority students and, between disadvantaged children and their more advantaged peers"…
