This article develops an algorithm to find all solutions to the problem, making all sums of a hexagram's nine lines the same. It shows how to exploit the geometric structure of the hexagram and its group of automorphisms. (YP)

Considers definitions of quantiles. Describes median and quartiles. Compares the usefulness of 3 different definitions of quartile using a computer program to simulate 500 quantiles on a sample of a fixed size. Five references are listed. (YP)

Discusses the issues faced by community college libraries when they add copyrighted microcomputer software to their circulating collections. Analyzes three possible responses: educating users about copyright requirements, encouraging user compliance with copyright law, and limiting the liability of the college and library for user violations. (DMM)

Provides a BASIC program to compute the number of shuffles required for packs containing even numbers of cards up to 100. Lists 4 further questions on the shuffling program. (YP)

Shows a series of Euclidean equations using the Euclidean algorithm to get the greatest common divisor of two integers. Describes the use of the equations to generate a series of circles. Discusses computer generation of Euclidean circles and provides a BASIC program. (YP)

This article discusses the impact of symbolic-manipulation systems on secondary school mathematics curriculum. Characteristics and possible roles for the symbolic systems are explored. Four references are listed. (YP)

Describes the results of an experiment designed to test the effectiveness of simple computer-assisted instructional software for sociology classes. Tests a computer tutorial on attribution theory. Found that students who took the computer tutorial did somewhat better on a quiz than the subjects did who only read the material. (KO)

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)

The paper examines ways to use word processing programs to ameliorate children's writing problems. Case studies of three children contrast samples of their handwritten work and their compositions using word processing A list of word processing programs for use with children with special needs is included. (Author/DB)

Discusses legal issues involved in developing and distributing multimedia publications. Examines libel; rights of publicity; and such elements of copyright law as copyright protections and infringements, fair use and public domain policies, and use of ideas and factual materials. Uses a hypothetical multimedia project to illustrate the legal rules…

A teaching method for introductory computer science based on visualization and using extensive amounts of software is explained. Visualization is used to integrate other student activities, including reading algorithm and data structure descriptions, studying code for model programs and toolkits, designing software components, and building or…

SIGMA (Simulation Graphical Modeling and Analysis) is a computer graphics environment for building, testing, and experimenting with discrete event simulation models on personal computers. It uses symbolic representations (computer animation) to depict the logic of large, complex discrete event systems for easier understanding and has proven itself…

Discusses educational effects of the style, content, and quality inherent in several multimedia and desktop-publishing products available to science teachers, including books, interactive software, videos, and computer simulations. (JJK)

Shows a way in which algebra and geometry can be used together to find the lengths and areas of spirals. This method develops better understanding of shapes, similarity, and mathematical connections in students. Discusses spirals embedded in triangles and squares, the Pythagorean theorem, and the area of regular polygons. (MKR)

Computerized bus-routing systems plot the most efficient routes, cut the time it takes to draw routes, and generate reports quickly and accurately. However, school districts often underestimate the amount of work necessary to get information into the computer database. (MLF)
