A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

A reduction in agricultural activity in a rural farming community will result in reduced activity in almost every sector of the local economy. The result may be measured in loss of employment and income. This report provides a method to estimate such economic impacts with a minimum of data collection and manipulation. Most of the input data…

Routines developed for an ongoing course in research methods and statistics provides examples of the custom instructional applications that can be created using extended BASIC and a light pen, including title and transition displays, progressive disclosure, animation, overlays, and simulations. Strengths of this technique are reviewed. (MBR)

Discusses the goals of the Computer Working Party in Great Britain, presenting their assessment of current computer hardware and the market for economics software. Examines "Running the British Economy," a macroeconomic policy simulation that investigates the links between values and policy objectives and encourages questioning of…

Describes a case-study simulation program designed to assist instructors in teaching ethics in psychology. Concludes that the program is useful for teaching ethics as it reveals the difficulty of ethical decision-making and generates, through student work, discussions on the moral bases for different ethical decisions. (Author/GEA)

This article describes a monte carlo computer simulation of affirmative action employment policies. The counterintuitive results of the model are explained through a thought device involving urns and marbles. States that such model simulations have implications for social policy. (BSR)

The expert system computer simulation detailed in this report is designed to investigate patterns of valuing in decision-making about dossiers of performance data used in teacher promotion evaluations. The knowledge base for the simulation consists of 111 questions organized into 117 rules. The questions and linked advice were derived from…

Evaluates MUSICSHAPES, a graphic music construction software program which manipulates sound in terms of pitch, rhythm, timbre, and sequence to help students create complex synthesizer compositions. Intended for ages eight to adult, the program utilizes Apple II computers and additional hardware. Discusses how MUSICSHAPES can be used effectively…

Discusses a computer software package, available for the Apple Macintosh, which simulates the economic and social climate during the reign of Louis XIV of France, 1638-1715. Describes the benefits of using the program as a tool for teaching social history. Includes a course outcome and brief bibliography. (GEA)

Reviews seven educational computer software packages covering such topics as presidential elections, the American Revolution, the Vietnam War, the construction of historical time lines, and general U.S. history. Also reviews a program designed to help tailor data entry files. Provides ordering information, price, and computer compatibility…

Discussed are the use of probability simulations in a mathematics classroom. Computer simulations using regular dice and special dice are described. Sample programs used to generate 100 rolls of a pair of dice in BASIC and Logo languages are provided. (YP)

Discussed are solutions to the problem "What is the expected number of rolls for the total first to exceed 6?" Several algebraic solutions are presented. A computer program which may be used to simulate this problem is included. (CW)

Related to the earlier ACT production system theory, this book's basic goal is to present evidence for the psychological reality of a production system model of mind. Distinguished from the original theory in three ways, this volume uses previous rational analyses to improve upon that theory and extend its scope. It also relates the theory to new…

Describes a computer program, "Activation Energy," which is designed for use in physical chemistry classes and can be modified for kinetic experiments. Provides suggestions for instruction, sample program listings, and information on the availability of the program package. (ML)

Describes the use of simulation to introduce the bootstrapping technique of creating confidence intervals for the mean, median, and variance. These bootstrap confidence intervals are compared to the traditional confidence intervals for the purpose of analyzing accuracy of the technique. A Minitab program to produce confidence intervals is…
