Computer graphics are used to display the sum of the first few terms of the series solution for the problem of the vibrating string frequently discussed in introductory courses on differential equations. (MNS)

How a computer randomly generates numbers to turn off lighted blocks on a graphics display is discussed. A computer program is given after reviewing a definition and two theorems and applying them to the problem. (MNS)

A problem is detailed which has a solution that embodies geometry, trigonometry, ballistics, projectile mechanics, vector analysis, and elementary computer graphics. It is felt that the information and sample computer programs can be a useful starting point for a user written code that involves missiles and other projectiles. (MP)

Describes a separate engineering administrative unit established to meet the needs of lower-division students. Need for the unit, courses that make up the basic program of instruction, advising, academic assistance, and advantages and disadvantages to the engineering college are discussed along with concerns and problems that have arisen. (BC)

Discusses constructive ways to use microcomputers as educational aids. Areas considered include software packages with graphics capabilities to help students visualize their work, programs fostering skill development (including problem-solving), microcomputer rentals, use of computers to learn programing languages, and others. (JN)

Investigates the mathematical behavior of 30 college students in a problem situation that requires them to find the inverse of a given compound element in an environment of LOGO turtle graphics. Results from interviews indicate that, in searching for the inverse, students tend to invert the elements but not the order. (MDH)

Discusses the use of a computer-illustrated text (CIT) with integrated software to teach electric circuit theory to college students. Examples of software use are given, including simple animation, graphical displays, and problem-solving programs. Issues affecting electric circuit theory instruction are also addressed, including mathematical…

Describes the construction and use of a microcomputer-based experimental system designed to examine the role of visual context in the analyses of data displayed in computer graphics. The responses of end users to changes in visual context of business graphics are examined, and future experiments are discussed. (Seven references) (LRW)

This paper describes a National Science Foundation-sponsored project at Louisiana Technological University to develop computer-based laboratories for "hands-on" introductions to major topics of computer science. The underlying strategy is to develop structured laboratory environments that present abstract concepts through the use of…

Both high school and college students served as subjects for an evaluation of the effectiveness of a computer-animated test of science problem-solving skills designed to minimize problems inherent in printed tests. The test development process is reviewed, and observations and conclusions relating to screen design and human interaction factors are…

Describes some commands, simple programing procedures, and applications of the programing language LOGO, including its powerful recursive feature and its value in teaching problem solving. A listing of LOGO graphics packages includes details of software and print materials, prices, and microcomputers that will support the packages. (EAO)

The social interactions that occur during pair problem solving were studied using a computer tool and without using the tool. The computer tool, (the TAPS system) is an instructional system that presents complex word problems and provides a graphics user interface with tools for constructing problem trees (network structures showing…

This paper describes GUIDON-WATCH, a graphic interface that uses multiple windows and a mouse to allow a student to browse a knowledge base and view reasoning processes during diagnostic problem solving. The GUIDON project at Stanford University is investigating how knowledge-based systems can provide the basis for teaching programs, and this…

Describes how the limitations of the built-in graphics capabilities of spreadsheet software can be overcome by making full use of the flexibility of the grahics options. Uses triangular plots with labeled field boundaries produced using Lotus 1-2-3 to demonstrate these techniques and their use in teaching geology. (CW)
