Evaluation is an act of persuasion directed to a specific audience concerning the solution of a problem. The process of evaluation is prescribed by the nature of knowledge--which is generally complex, always uncertain (in varying degrees), and not always propositional--and by the nature of logic, which is always selective. In the process of…

The study, a seventh in a series of longitudinal studies, was an investigation of causal and other relationships among leadership, climate, teacher, and student variables in curriculum engineering. Quantitative measures included principals' leadership, organizational climate, teachers' attitudes, teachers' performance, and students' achievement.…

In this paper, the author attempts to clarify several implicit hypotheses about local school finance reform, set up tests whereby hypothesis validity can be affirmed or rejected, and outline the policy implications of the results. Two mathematical models of school district behavior are examined, and their implications are tested on a sample of 150…

The purpose of this study was to determine whether option weighting improved the internal consistency and intercorrelation of the subtests. The differential option-weighting scheme employed in this study is based on one devised by Guttman. The tests were first scored with Guttman-type weights and then with conventional correction-for-guessing…

This study presents evidence that differences in mathematical career outcomes of males and females are the result of early socialization in the family. One reason fewer females than males elect to take high school mathematics courses is that during middle school years females perceive low parental evaluations of their mathematical aptitude and…

Using data from the National Longitudinal Survey for men aged 45 through 59, the paper develops a model of labor supply change or adjustment to estimate the speed of worker response to changes in desired labor supply and to constraints on hours and wages. (MF)

A study to determine whether the same faculty members would be dismissed when faculty staffing decisions were based solely on institutional personnel management constraints as when the decisions were further constrained to preserve disciplinary integrity is described. Two sets of constraints were entered into an integer linear programing model.…

Presents three teaching ideas: (1) a scoring rubric to assess students' ability to communicate attempts at solving homework problems; (2) a three-part measurement activity using trigonometry, maps, and compasses to locate hidden treasure; and (3) a demonstration of the effects of numerical coefficients on graphs of quadratic functions. (MDH)

Discusses the use of technology in solving compound interest-rate problems that can be modeled by linear relationships. Uses a graphing calculator to solve the specific problem of determining the amount of money that can be borrowed to buy a car for a given monthly payment and interest rate. (MDH)

This second report on a two-part study on the application of informetrics to information retrieval (IR) system design used models of database contents in a factorial simulation study at the University of Western Ontario. The study explored whether different file structures were better suited for different informetric environments. (32 references)…

A study evaluating South Carolina's postsecondary enrollment patterns by race and institution estimated enrollment probabilities by races, institutional type, and year during the five years following court-ordered desegregation of public colleges and universities. Findings show evidence of gradual progress toward desegregation in postsecondary…

Discusses the potential that school mathematics has for being a source of exploration and discovery for students and teachers. Provides a process-oriented definition of understanding mathematics. Presents activities in which students construct computer and actual models of polyhedra and make conjectures regarding a medical research application of…

The cognitive structure of an algebra test was defined and validated using the linear test model (LLTM) and quadratic assignment (QA) techniques. The LLTM is an extension of the Rasch model with a linear constraint that describes item difficulty in terms of the cognitive operations required to solve the item. The model permits the specification of…

The focus of this report is children's construction and analogical transfer of mathematical knowledge during novel problem solving, as reflected in their strategies for dealing with isomorphic combinatorial problems presented in "hands-on" and written form. Case studies of 9-year-olds, one low and one high achieving in school…

The impact of test item multidimensionality was examined as it affected fitting items on a teacher licensure test to an item response theory (IRT) model. Test item data from the 1990 study of G. W. Guiton and G. Delandshere are used. The Connecticut Elementary Certification Test (CONNECT) is a licensure examination designed to assess the subject…
