This collection of activities is intended to enhance the teaching of college algebra through the use of modeling. The problems use real data and involve the representation and interpretation of the data. The concepts addressed include rates of change, linear and quadratic regression, and functions. The collection consists of eight problems, four…

A confirmatory factor analysis was used to determine the respective viability of factor structure models for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization data. The traditional verbal-performance split was compared to an alternative model proposed by Gutkin, Reynolds and Galvin. The confirmatory analysis indicated that the…

Complex decision-making environments often demand that a range of alternative strategies be identified and compared for their shared value in achieving desired ends. Simple parametric statistical procedures such as analysis of variance and discriminant function analysis can be used in such situations to compare (using selected criteria) the value…

Based on the game "Prisoners' Dilemma," a game-theoretical model of the arms race suitable for postsecondary level mathematics and/or political science students is developed in which two players can initially choose any level of arms development. The purpose of the game is to show under what conditions deescalation rather than escalation…

Hardware for computer-assisted learning is discussed in three papers. Two papers report on projects using computer graphics, one for teaching structural analysis to university students and the other to teach graph concepts at the secondary level. Guidelines for selecting microcomputers focus on analyzing applications and matching them with…

Analytical techniques used in responding to a series of four substantial budget reductions imposed at Oregon State University are described. Over a 2-year period, each of the budget reductions demanded increasingly severe institutional action to meet the specified monetary targets. Different analytical techniques were required to meet the changing…

The kaleidoscope is presented as a suitable topic for a preservice mathematics teacher's first contact with a nontrivial mathematical phenomenon. Included are historical notes on the kaleidoscope, explanation of the inner mechanisms of various kaleidoscope designs, and suggestions for further student investigations. (JJK)

Policy Analysis and Simulation System (PASS) is an interactive microcomputer model that can be used by educational administrators, policy-makers, and planners to simulate and forecast, under conditions of environmental uncertainty, the impact of strategic policies on the projected trends and goals of educational performance. PASS generates…

This study used the restricted access database of the 1993 National Study of Postsecondary Faculty to examine faculty workload by academic discipline for full-time regularly appointed teaching and research faculty in public Carnegie research I and II and Doctoral I and II institutions (n=2,056). Data are reported for 14 disciplinary areas…

When one encounters a problem that one has no adequate way of representing, a new mental model for the problem may have to be found. When a possible model is found, an important next step is to evaluate the validity of the model. In this document, examples of subjects finding and evaluating mental models used as problem representations are…

The issues of achieving school desegregation and providing programs for students with special needs, while at the same time facing enrollment declines, have forced school administrators to improve techniques for projecting demand. This paper describes a new procedure that combines forecasting of enrollments and management of facilities and that…

Despite the fact that one of the strengths of two-year institutions is their ability to serve the diverse educational needs of their local communities, a single measure of community college effectiveness, the transfer rate, has come to dominate. Because this single measure of success can be used for both internal institutional review, and for…
