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…

The logic and methodological concepts behind the application of a quantitative methodology to the problem of effective resource utilization in the New York State suburban schools is detailed. The goal of the study was to determine the best composition of available "factors of production," measured in dollar amounts by function, that…

Modeling and data collection efforts needed to develop a test of the effectiveness of adult literacy and language training programs in increasing the earnings of trainees are reviewed. After reviewing the framework developed for the Manpower Development and Training Act and the Comprehensive Employment and Training Act (CETA) evaluations and the…

The internal/external (I/E) frame of reference model describes relations among Verbal self-concept (VSC), Math self-concept (MSC), and corresponding achievement scores (VACH, MACH). In support of the model Marsh (1986) found that: (1) VSC and MSC were nearly uncorrelated; (2) the effect of VACH on VSC, and of MACH on MSC, were positive; but (3)…

This paper discussed methods currently under study for use with multiple-response data. Besides using Bonferroni inequality methods to control type one error rate over a set of inferences involving multiple response data, a recently proposed methodology of plotting the p-values resulting from multiple significance tests was explored. Proficiency…
