Describes instructional use of a microcomputer version of the WORLD2 global population-ecology simulation. Reactions of students and instructors are discussed and a WORLD2 simulation assignment is appended. The BASIC version used by the author runs on Apple II, DOS 3.3, with 80 column board. (MBR)

Describes a microcomputer-based software package, Online Search Tutor (OST), which is designed to teach users online bibliographic searching. Modeled on software previously developed for the European Space Agency Information Retrieval Services (ESA-IRS), OST includes a database of 600 bibliographic records which will simulate actual search…

The structure, execution, uses, and software specifications for this spreadsheet file are discussed. Availability and modifications of this program are described. (CW)

A mechanical analogy between the microscopic motion of a charged carrier in an ordinary resistor and the macroscopic motion of a ball falling along a slanted board covered with a lattice of nails is introduced. The Drude model is also introduced to include the case of inelastic collisions. Computer simulation of the motion is described. (KR)

Described is a Monte-Carlo method for modeling physical systems with a computer. Also discussed are ways to incorporate Monte-Carlo simulation techniques for introductory science and mathematics teaching and also for enriching computer and simulation courses. (RH)

The principle of the multiplier-accelerator interaction is explained, and how a computer program to model it can be developed is shown. A series of simulations that can be used to explore the model's behavior are suggested. The simulations can be used in college-level economics classes. (Author/RM)

The expected thrust for theoretical chemistry in the next decade will be to combine knowledge of fundamental chemical steps/interactions with advances in chemical dynamics, irreversible statistical mechanics, and computer technology to produce simulations of chemical systems with reaction site competition. A sample simulation (using the enzyme…

Described is a computer program, AQUASIM, which simulates interaction between environmental factors, phytoplankton, zooplankton, and fish in an aquatic ecosystem. The conceptual flow, equations, variables, rate processes, and parameter manipulations are discussed. (CW)

A rationale is presented for viewing the decision-making process inherent in determining budget reductions for educational programs as most effectively modeled by a graduated funding approach. The major tenets of the graduated budget reduction approach to educational fiscal policy include the development of multiple alternative reduction plans, or…

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…

Describes a computer-based instructional unit in cardiovascular physiology. The program (which employs simulated laboratory experimental techniques with a problem-solving format is designed to supplement an animal laboratory and to offer students an integrative approach to physiology through use of microcomputers. Also presents an overview of the…

Describes the emphasis of decision support systems as being on the decision making process itself, rather than the flow of information; reviews the uses of microcomputers in libraries in recent years; and compares five decision modeling software packages. An appendix lists the name, manufacturer's address, price, and hardware requirements of each…

Presents a model for building a concept-oriented computer simulation which involves five steps: (1) topic selection and resource gathering; (2) developing objectives and lesson activities; (3) selecting and formulating simulation factors; (4) program coding and debugging; and (5) developing student worksheets. Students act as tax advisors in the…

Suggests the use of computer simulation of continuous systems as a problem solving approach to computer languages. Outlines the procedures that the system dynamics approach employs in computer simulations. Explains the advantages of the special purpose language, DYNAMO. (ML)

Cites advances in x-ray diffraction, nuclear magnetic resonance, computer modeling, and display to guide the design and analysis of protein structures. Reviews recent advances in knowledge, synthesis techniques, and theory of proteins. (JM)
