Noting that mathematical modeling is a relatively new phenomenon in higher education and that much can be learned from the misdirections and mistakes that characterize modeling in general, the author describes major criticisms of modeling and suggests improvements, particularly in communication between modelers and potential model users.

By using complex multiple regression models to generate regression surfaces, the relationships between academic achievement, creativity, and intelligence are examined. Findings indicate that for certain academic subjects creativity is related to achievement up to a threshold level of intelligence, but after the threshold has been reached…

This article presents a short method for computation of the doubling period of a population at a fixed rate of annual increase. (Author)

Analyzing the effects of tilting a probability board can be an effective method of introducing a discussion of models in a probability class. (SD)

The author discusses the impact of mathematical developments around the turn of the century, and historical concerns and development of mathematics education. This article is a continuation of SE 515 504. (SD)

After considering the mathematical system common to various types of measure, the author argues that instruction needs to reflect the common aspects of measure systems as well as the distinctive attributes of different systems. (SD)

Since the statistical theories of turbulence that have developed over the last twenty or thirty years are too abstract and unreliable to be of much use to chemical engineers, this paper introduces the techniques of single point models and suggests some areas of needed research. (BB)

This study sought to develop and test a method for predicting inpatient utilization in the New York State Department of Mental Hygiene. A Markov chain mathematical model was developed and tested ex post facto for its accuracy in prediction of inpatient workload by age groups for two successive fiscal years. (Author)

The purpose of this paper is to present problems (and solutions) from the areas of marketing, population planning, system reliability, and mathematics to show how a computer simulation can be used as a problem-solving strategy in probability. Examples using BASIC and two methods of generating random numbers are given. (Author/MP)

Presents some problems for quantum chemistry courses based upon model pseudopotentials. Also includes some useful formulas and tables of parameters associated with these problems. (HM)

Describes a learning activity when students construct a model of a buried valley by using computer assistance. Explanation of the problem includes mathematical models and illustrations. (MA)

The answer-until-correct (AUC) procedure requires that examinees respond to a multi-choice item until they answer it correctly. Using a modified version of Horst's model for examinee behavior, this paper compares the effect of guessing on item reliability for the AUC procedure and the zero-one scoring procedure. (Author/CTM)

Describes an interactive computer program which can be used by students to construct adaptive landscapes of two types as an illustration of the expected effects of selection. Simulates effects of selection on populations of this type and changes of gene frequency can be plotted on the same contour map. (Author/MA)

Using a linear loss function, a procedure is described for computing a cutting score that minimizes the risk for a given decision rule. The procedure is demonstrated with a criterion-referenced achievement test of elementary statistics administered to 167 students. (Author/CTM)

This research tested Paivio's (1971) proposal that pictorial and verbal memory codes interact with space and time. This "interaction hypothesis" states that pictorial memory codes are specialized for spatial structures and verbal memory codes are specialized for temporal structures. Tests this hypothesis by exploring several variations…
