Results of applying different aptitude-achievement discrepancy models for test scores were compared for 150 second, 150 third, 150 fourth, and 130 fifth graders in several school systems in the Southeast who had been referred for psychoeducational testing for learning disabilities to determine whether different groups of students were identified…

Current research and learning theory suggest that a hierarchy of proportional reasoning exists that can be tested. Using G. Vergnaud's four complexity variables (structure, content, numerical characteristics, and presentation) and T. E. Kieren's model of rational number knowledge building, an epistemic model of proportional reasoning was…

This study examined the relationships between ATM (asynchronous transfer mode) adoption in universities and four organizational variables: university size, type, finances, and information processing maturity. Another purpose of the study was to identify the current status of ATM adoption in campus networking. Subjects were university domain LAN…

The purpose of the study was to compare two regression-based approaches for measuring educational effectiveness in Tennessee high schools: the mean residual approach (MR), and a more general linear models (LM) approach. Data were obtained from a sample of 1,011 students who were enrolled in 48 high schools, and who had taken the Comprehensive…

This paper explores the feasibility of neural computing methods such as artificial neural networks (ANNs) and abductory induction mechanisms (AIM) for use in educational measurement. ANNs and AIMS methods are contrasted with more traditional statistical techniques, such as multiple regression and discriminant function analyses, for making…

Researchers have been limited in their ability to examine multiple constructs simultaneously due to the constraints imposed by traditional statistical methods. The most notable limitations include the need for a relatively large sample size while restricting the variables to a relatively small number. The application of a newly discovered…

The quantitative methods of regression and factor analysis were used to study the equity of educational outcome and the effectiveness of schools in 30 sixth-grade classrooms in western New York State. Equity of educational outcome refers to a situation in which educational achievement is fairly and justly distributed across racial and…

Eighty-three students enrolled in five graduate sections of educational research taught by the same instructor were administered a reading attitude scale and an educational research attitude scale. Under-graduate grade point averages (GPAs), entering graduate GPAs, and composite National Teacher Examination (NTE) scores were also obtained for the…

The attitudes and self-beliefs revealed in science education can affect students' achievements. Several studies have found that students' self-beliefs are significantly associated with achievement outcomes. The purpose of this study was to investigate the relationship between their attitudes and self-beliefs and science achievements based on TIMSS…

The general features of function-specific assessment are described and illustrated via a discussion of the design and development of "The Reading Biographer," an instrument for assessing experiences and activities of students (from early childhood through high school) that affect their reading achievement as high school seniors. The…

An interstate cost-of-living index from SMSA-level market basket data is generated in this research. Models are developed for each of the four regions--Northwest, North Central, South, and West--to explain differences in the cost of living among more than 180 SMSAs. Weighted regression coefficients were combined with comparable state-level data to…

One approach to identifying effective schools defines effectiveness in terms of student achievement in reading, mathematics, and language usage. Exceptional school achievement is indicated by performance above or below the level expected if students were merely to maintain their previous rate of growth. Regression analysis is used to compute…

Although methodological integrity is not the sole determinant of the value of a program evaluation, decision-makers do have a right, at a minimum, to be able to expect competent work from evaluators. This paper explores five areas where evaluators might improve methodological practices. First, evaluation reports should reflect the limited…

Four tests were pre-equated on the basis of item-test regressions computed from a large sample providing pretest data. The tests were two mathematics tests (math computation and elementary algebra) and two verbal tests (sentence sense and reading comprehension) from the New Jersey College Basic Skills Placement Test. Regular equipercentile…

Online collaborative learning has typically been studied within the context of learning communities. Little is known about the potential influence of students' personalities on online communication, group interaction, and task engagement among members of a learning community. This study used a mixed-method, triangulation design, involving the…
