Described is the computer simulation program "PH." The program consists of three different laboratory investigations dealing with the pH specificity of enzymes. The purpose of the program is to enable tenth- to twelfth-grade students to determine a possible explanation for pH specificity in an experimental, but mathematical, fashion.…

Described is the population growth computer model "POP." This program is designed to allow a student with little mathematical background to explore various simple mathematical models of population growth. Student exercises revolve around the growth of a gypsy-moth population. Three variations of population modeling are included in POP:…

Described is the computer model "MALAR" which deals with malaria and its eradication. A computer program allows the tenth- to twelfth-grade student to attempt to control a malaria epidemic. This simulation provides a context within which to study the biological, economic, social, political, and ecological aspects of a classic world…

Described is the use of the computer model "BUFLO." BUFLO is a simulation which allows students to study the historical and biological reasons for the extinction of the buffalo. BUFLO simulates the natural life cycle of the buffalo and allows the student to manipulate harvesting policies to reach certain goals outlined in the student handbook.…

Two units make up this material. They focus on applications of second-order difference equations to American politics. The goals of the first module include helping the user understand: 1) the difference between a theoretical construct and an observable; 2) the nature of choices which exist in modeling any particular empirical phenomenon; and 3)…

Presented are instructions for the use of "TAG," a model for estimating animal population in a given area. The computer program asks the student to estimate the number of bass in a simulated farm pond using the technique of tagging and recovery. The objective of the simulation is to teach principles for estimating animal populations when they…

This document is addressed primarily to students in analytically oriented courses in political science and secondarily to students in mathematics courses in which applications and modeling are stressed. Except for one optional exercise and material in the appendix, only high school level mathematics is assumed. The emphasis is less on mathematical…

Presented are instructions for the use of "RATS," a model simulating the dynamics of a rat population in either a city or an apartment house. The student controls the conditions of growth and sets the points at which the computer program prints reports. The rat population is controlled by variables including garbage levels selected for the site,…

This unit views applications of elementary game theory to international relations. It is noted that of all the significant world problems, the nuclear arms race has proved one of the most intractable. The main concern of the module is to investigate a possible solution to the arms race, based on extending the classic two-person game of Prisoner's…

This document consists of two modules. The first studies a variety of multicandidate voting systems, including approval, Borda, and cumulative voting, using a model which takes account of a voter's intensity of preference for candidates. The voter's optimal strategy is investigated for each voting system using decision criteria under uncertainty…
