"TK!Solver" was designed as a personal computing tool to solve problems involving mathematical calculations and analysis. An in-depth review of this model building and problem-solving package is provided. System commands, applications (including data lists, plots/graphs, iterative problem-solving, present values), and other areas are…

A large-scale computer managed training program in problem-solving in applied mathematics and basic physics for first-year medical students at the University of Leuven is described. Students do calculations away from the terminals, but are corrected and evaluated at terminals. Some tentative results are presented. (Author/MSE)

Presents an interview with Erno Rubik, creator of "Rubik's Cube." Included are comments about the creation of the cube and the role of the cube in educating people, especially in problem-solving activities. (JN)

The difficulty many students have in solving complex problems stems not from a lack of mathematical skill but from an inability to visualize the problem. An appropriately-structured computer game may assist students in achieving this visualization and in solving problems better. A heuristic approach in programing one game is provided. (Author/JN)

Describes the current use and potential of the LOGO programing language in a variety of educational situations. (JL)

The material is designed to help students build a cone model, visualize how its dimensions change as its shape changes, estimate maximum volume position, and develop problem-solving skills. Worksheets designed for duplication for classroom use are included. Part of the activity involves student analysis of a BASIC program. (MP)

The problem involves randomly breaking a stick into three pieces and using the pieces to form a triangle. The probability of getting a triangle is calculated using four different solution methods. Two unique problem interpretations are noted, and one solution method involves a BASIC program. (MP)

Examples are provided which demonstrate the use of the computer as an instructional aid for the algebra curriculum. While the basic content of an algebra course would remain intact, computer technology can enhance and expand methods of algebra instruction. (JN)

Instruction using computers is viewed as different from most other approaches to education, by allowing more than right or wrong answers, by providing models for systematic procedures, by shifting the boundary between formal and concrete processes, and by influencing the development of thinking in many new ways. (MP)

Errors students typically generate while trying to translate problems into and out of algebraic notation are reviewed. Translation skills and pupil difficulties with them are seen as areas deserving further research. (MP)

Spatial concepts are important to the development of many skills, including reasoning and problem solving. Here are guidelines for making geometry learning more effective for elementary-grade students. (Editor)

Krutetskii's claim that good problem solvers differ from poor ones both with respect to solution performance and nature of their recall of problem information is supported by this study. The use of recalled information in the solution of related problems is also examined. (MP)
