Discusses development of an analog simulation program for microcomputers similar to those available on mainframe computers. The program is interactive, more user-friendly than batch mode mainframe simulators in use, and has user help, error detection, and medium resolution graphics for presentation of system responses. (JN)

Describes a relatively inexpensive system which allows students in a digital control course hands-on experience in the implementation of control algorithms on a variety of processes. The system uses two computers, one for real time simulation of the process and the other for implementation of the digital control algorithms. (JN)

The macroeconomic model in Ray C. Fair's textbook, "Specification, Estimation, and Analysis of Macroeconometric Models" (Cambridge: Harvard University Press, 1984), has been programed to run on a personal computer. The model consists of 128 equations. The model's potential for use as a teaching tool is discussed. (RM)

Describes a program which simulates the kinetic behavior of a "typical" enzyme. Program objectives, background to the kinetic model used in the simulation, major program features, typical results obtained, and a note on the availability of the program (written in BASIC for Commodore microcomputer) are included. (JN)

Describes a computer program which plots electric field line plots. Includes program listing, sample diagrams produced on a BBC model B microcomputer (which could be produced on other microcomputers by modifying the program), and a discussion of the properties of field lines. (JN)

Presents the listing for a TRS-80 Model III program which illustrates the first law of robotics (all robots must be programed so that none of their actions will be harmful to man). Also discusses the rational for and development of the program. (JN)

One way in which a computer simulation can convince students of the validity of formulas for the density and distributive functions of the sum of two variables is described. Four computer program listings are included. (MNS)

Some of the advantages of using computer simulations in social studies are examined, and criteria to help social studies teachers select worthwhile social studies simulations are discussed. (RM)

Two computer programs that simulate the multiplier and accelerator processes are described. The simulations can be used in college-level economics classes or by pupils using their own personal computers at home. Very little knowledge of programing is required to implement the simulations. (Author/RM)

Presents algorithms for the simulation and motion display of the three basic kinematic devices: (1) four bar linkages; (2) the slider crank; and (3) the inverted slider crank mechanisms. The algorithms were implemented on a Commodore-VIC 20 microcomputer system with 6500 bytes of available memory. (Author/JN)

Describes a computer program that can model the equilibrium processes in the production of ammonia from hydrogen and nitrogen, sulfur trioxide from sulfur dioxide and oxygen, and the nitrogen dioxide-dinitrogen tetroxide equilibrium. Provides information about downloading the program ChemEquilibrium from the World Wide Web. (JRH)

An interactive computer program in microbial genetics is described. The simulation allows students to work at their own pace and develop understanding of microbial techniques as they choose donor bacterial strains, specify selective media, and interact with demonstration experiments. Sample questions and outputs are included. (DH)

Describes five categories of computer programs useful for content area reading instruction: utility programs, word processing, simulations, telecommunications for access to a database, and story architecture. (HOD)

Seven possible applications of microcomputers in high school science programs are discussed. They include computers as calculators, computers as black-box number crunchers, computers for teaching computer literacy, computers as blackboards, computer-assisted instruction, computer simulations, and process control. (JN)

Presented are two problems that can be solved using a computer simulation by students who have completed Algebra II. The distance and bisector formulas and the various forms of the equations of a circle and straight line are the topics. Computer program listings are included. (MNS)
