Describes a Fortran program that illustrates how the end-to-end distances in randomly coiled polymer molecules is affected by varying the number and lengths of chains and the angles between them. (MLH)

Describes interactive computer program (listing available from author) which simulates olivine fractionation from basaltic/ultrabasic liquid. The menu-driven nature of the program (for Apple II microcomputer) allows students to select ideal Rayleigh fractionation or equilibrium crystallization. (JN)

Describes a science program that operates by obtaining, testing and distributing copies of computer programs among its members. (LS)

Describes one program each for performing Fourier analysis and synthesis with a Hewlett-Packard HP-25 calculator. (MLH)

Describes interactive, geology programs (GEOPACK) for use in geostatistical applications, demonstrations and reviews, and geocartography. Programs, designed for beginning and advanced students, make use of the graphics capabilities of the Apple II microcomputer. (JN)

Reports on efforts to develop interactive general purpose programs (for very inexpensive microcomputers) to be used in engineering systems courses. Programs discussed (Microsoft Basic) include: (1) polynomial root finder; (2) partial fraction expansion; (3) transfer function frequency response; (4) transfer function simulator; and (5) Fourier…

Reviews three organic chemistry computer programs for TRS-80 and Apple microcomputers. Programs include "Introduction to Organic Chemistry,""Qualitative Organic Analysis," and a game called "Chemrain." Indicates that all three produce a readable screen, require exact responses, use graphics in an appealingly and…

Explains the educational value of computer simulations in general and provides specific areas of computer application in teaching of chemistry, biology, and physics. Explains the application of instructional materials developed in the Chelsea Science Simulation Project. (GS)

A particularly difficult area for many engineering students is the approximate nature of the relation between models and physical systems. This is notably true when the models consist of differential equations. An approach applied to this problem has been to use analog computers to assist in portraying the output of a model as it is progressively…

Simulates the problems of rocket propulsion, hovering, and soft landing. (GS)

Describes the adaption of a simple homogeneous analogue computer for the solution of the Schrodinger wave equations. Photographs of results are included. (CP)

Seven styles of software which may significantly improve mathematics and science learning are discussed. These include microworlds, educational games, microcomputer-based instrumentation, databases, tools, languages, and simulations. Opportunities and need for new software are also discussed, suggesting such items as a scientific text processing…

A program written for the Apple II microcomputer that plots the "one-S" orbital of an atom is described. The material is used to move from the Bohr model of the atom to the quantum mechanical description. (MP)
