Some researchers have argued that discrepant broad index scores invalidate IQs, but others have questioned the fundamental logic of that argument. To resolve this debate, the present study used a nationally representative sample of children (N = 1,200) who were matched individually for IQ. Children with significantly uneven broad index score…

Supplemental Educational Services (SES), a component of the No Child Left Behind (NCLB) Act, provides free tutoring to economically disadvantaged children who are attending Title I schools in their 2nd or more years of school improvement. This research evaluated SES in Tennessee to determine the: (a) impacts on student achievement, and (b)…

This study found no differences in the performance of middle class black and white children on three ability measures. The sample consisted of 15 pairs of black and white middle class children, aged 2.5 to 6.5 years, who attended the same mid-south child development center during 1987-88. Variables on which the children were match-paired were the…

Considers the relationship between coordinate estimates in components analysis and multidimensional scaling. Reports three small Monte Carlo studies comparing nonmetric scaling solutions to components analysis. Results are related to other methodological issues surrounding research on the general ability factor, response tendencies in…

Differential item performance (DIP) is discussed as a concept that does not necessarily imply item bias or unfairness to subgroups of examinees. With curriculum-based achievement tests, DIP is presented as a valid reflection of group differences in requisite skills and instruction. Using data from a national testing of the ACT Assessment, this…

To assess the effects of correlated abilities on test characteristics, and to explore the effects of correlated abilities on the use of a multidimensional item response theory model which does not explicitly account for such a correlation, two tests were constructed. One had two relatively unidimensional subsets of items, the other had all…

The chi-square procedure has been suggested as a viable index of test bias because it provides the best agreement with the three parameter item characteristic curve without the large sample requirement, computer complexity, and cost. This study examines the effect of using different numbers of ability intervals on the reliability of chi-square…

Presents a procedure for analyzing statistical data involving distributions that is more informative about causal and other relationships. Finds test scores were affected positively by increased time on task, teachers with higher educational attainment, and better school facilities. (CFR)

This study evaluated effects of two governmental financial aid programs to increase student access to higher education: the Florida Bright Futures Scholarships (FBFS) and the Federal Tuition Tax Credit (FHOPE). The FBFS program, similar to the Georgia HOPE (Helping Outstanding Pupils Educationally) scholarship program, rewards academic performance…

Reintroduces and updates the geographic profile as a visualization technique for representing and analyzing the structure of geographical information. A computer software-generated profile focuses on specific information (persons per square mile in selected cities) and represents that information spatially on a graph. (MJP)

This volume presents a comprehensive review of current research on the implementation of quality arts programs in U.S. schools, and an indicator of areas that need to be explored, with emphasis on community priorities and initiatives. The 49 quantitative and qualitative reports, articles, and dissertations are divided into five sections: (1) six…
