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…

The purpose of this study was to predict occupational choices based on demographic variables and high school curriculum tracks. Based on an analysis of the 1997 National Longitudinal Survey of Youth (NLSY) data set that examined high school graduates' occupational choices in 2006, findings indicated that CTE graduates were 2.7 times more likely to…

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…

The current study examines the views of experts in the science of mental abilities about the primacy and uniqueness of "g" and the social implications of ability testing, and compares their responses to the views of a group of non-expert psychologists. Results indicate expert consensus that "g" is an important, non-trivial determinant (or at least…

Results indicate that a common prediction system is not practical and that a separate prediction system should be developed for each subgroup. (AG)

The validity of estimates of peak oxygen consumption (VO[subscript 2]peak) using submaximal exercise tests may be compromised when the participants being tested are not similar to the participants used to develop the test. This study compared ethnic differences in the heart rate (HR) and oxygen consumption (VO[subscript 2]) responses to submaximal…

This study looked at Medical College Admissions Test (MCAT) scores by race in relation to medical college status. It was found that promoted students differed significantly on all four MCAT subtests from those dismissed for academic difficulties and those repeating a year. For both black and white racial groups, the latter two status categories…

Although a number of studies have been conducted to examine the status attainment process, very few have focused on differences in educational attainment for black, white, and Hispanic females. The primary purpose of this study was to test predictive models of attainment for these subgroups. Variables considered potentially important to the…

The predictive validity of the Scholastic Aptitude Test (SAT) for Mexican-Americans is investigated. Forty-two Mexican-American freshmen students who entered the University of California, Riverside, in the Fall 1971 participated in the study. Analyses of variance concerning ethnic groups on GPA (grade point average) and SAT verbal (SATV) and math…

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…

Differential prediction of grade point average for black and white freshman students was empirically investigated at 13 integrated institutions by comparison of regression planes. Particular attention was given to the possibility that prediction procedures that are appropriate for white (majority) students would under-predict the performance of…

Regression lines for the prediction of Wide Range Achievement Test (WRAT) scores by Wechsler Intelligence Scale for Children (WISC) and WISC Revised (WISC-R) intelligence quotients were compared across race, by the Potoff technique. Subjects were 36 black and 30 white children who were referred for psychological evaluation because of learning or…

The effectiveness of the freshman admissions prediction equation (FAPE) at the University of Georgia (Athens) was studied, using data for 3,378 freshman (1,490 males and 1,888 females) in 1987-88. For the 1987-88 data, a previous (1982) prediction equation functioned poorly in terms of predictive accuracy. New prediction models were constructed…

Some of the controversial issues involved in the use of objective tests by institutions of higher education, as this use affects the selection and attendance by members of minority groups, are reviewed. Admissions committees now rely on the ability of a test to predict students' performance at their institution to guide their selection. However,…

Research conducted by the Law School Admission Council since the development of the Law School Admission Test (LSAT) in 1948 is described. An overview of the research topics is provided, and relevant published reports are cited in 61 footnotes. The following topics of study are discussed: (1) use and validity of traditional predictors of law…
