The nature of instruction in a computer club that is open only to seventh to ninth graders is detailed. The club has access to five TRS-80 Model II computers, and membership is limited. Students are instructed from the beginning in graphics. Examples of program assignments are listed. (MP)

A computer program is presented which simulates the classical probability machine, using Applesoft II high-resolution graphics. Many variables are left to the user's choosing. Suggestions for using the machine, understanding the problem, the mathematical model, and further program documentation are given. (MNS)

The use of microcomputers to aid geometry instruction is emphasized through discussion of a program written in BASIC which provides for experimenting with polynomial curves. The program listing is included. (MP)

Provides examples of such statistical graphs as line, bar, picture and pie. Suggests uses of Logo Turtle Graphics in graph construction. Includes several program procedures for creating designs with the computer. (RT)

Reviews "Dueling Digits," an arcade-style computer game, in which the player creates mathematical equations. Discusses features of the program, educational value, design quality, documentation, and ease of use. Tested on Apple II/Apple II-Plus, the program (requiring 48K, disk drive and game paddles/joystick) is rated as an excellent…

Describes topics and applications of five lessons dealing with applied mathematics (solving sequential optimization problems, queuing theory, graph theory, glyphs (pictorial techniques for displaying relationships among variables, medical mathematics). Design and evaluation of these materials which employ interactive graphics are also described.…

Considers activities that use LOGO to slide, turn, and flip the "turtle." Uses non-LOGO tools such as cutouts, pattern blocks, and tangrams to enhance the motion work. Provides examples and programs with explanations. (MVL)

Presents the results of a preliminary investigation into the feasibility of teachers constructing their own animations for the mathematics classroom using computer animation tools. Provides examples of animation constructed using "Ani ST" and "Mathematica" programs. Concludes that computer animation has potential to be a…

Builds on a National Science Foundation (NSF) microcomputer based laboratory project to introduce system dynamics into the precollege setting. Focuses on providing students with powerful and investigatory theory building tools. Discusses developed hardware, software, and curriculum materials used to introduce model building and simulations into…

Describes the processes involved in leading students from the basics of MaxMix courseware to the final investigation. Discusses a mathematical game, number and graphic tasks included in the package, along with invoking meaningful interaction and integration into classroom mathematics. (RT)
