Presents a paper-folding method to develop a class repertoire of construction methods for the ellipse, hyperbola, and parabola using straws, rulers, dental floss, paper circles, and other household items. Uses the Geometer's Sketchpad software to complement the paper-folding process. (MKR)

Discusses the distinction between drawing and constructing in dynamic geometry environments. (MKR)

Shows how five points determine the formula of a conic section and uses the determinant as a computational device to find the coefficients in the formula. Uses symbolic, numerical, and graphical techniques. (Author/MKR)

Discusses a method that uses spreadsheets to calculate the exact distribution of the sum of two or more discrete random variables with arbitrary distributions. Demonstrates how this method can be used to investigate several problems that would be found interesting at the elementary level. (Author/ASK)

Presents the computer software Mathemagic, a remedial teaching system for high school mathematics. Describes a preliminary study that showed that the software could provide effective remediation to students. (Author/ASK)

The capacity of the "Geometer's Sketchpad" to trace the path of points by drawing the position of the point at different times provides a powerful tool to help see how velocities are related. Provides a snapshot of the process, along with the traces. (Author/ASK)

Describes the use of spreadsheets as an alternative means of teaching complex mathematical concepts through simulation using the topic of the statistical power of tests as an example. Through the simulation it is possible for the learner to explore the design factors that influence power. Also provides a simple way of calculating power as a…

Discusses the place of linear programming in college curricula and the advantages of using linear-programming software. Lists important characteristics of computer software used in linear programming for more effective teaching and learning. (ASK)

Describes and reports some results from a project designed to evaluate the use of information technology (IT) for teaching and learning on a range of undergraduate mathematics courses at a U.K. university. Focuses on students' tales of resistance, although many students were positive about the use of IT. Suggests that these tales spring from…

Identifies some trends in geometry teaching and illustrates them with reference to some of the more common software packages and their application and possible implications for junior high school geometry teaching and learning. (Contains 23 references.) (ASK)

Describes an investigation into the effects of introducing scientific software into the learning experience of a large and diverse first year university mathematics class on attitudes and learning. Confirms the affective potential of this kind of technology. (Contains 16 references.) (Author/ASK)

Activities designed to help mathematics teachers integrate information technology into lessons. Activities are based on using the software package !Draw. (MKR)

Examines issues relevant to the development, implementation, and evaluation of educational software in mathematics in the particular context of a Mathwise module covering the topic of complex numbers. Presents results of an evaluation exercise and some conclusions on issues of design and implementation. Contains 13 references. (ASK)

Describes in detail several activities designed for students studying dynamics. Incorporates life-related mathematical modeling and practical work. Uses computer technology as a tool. (Contains 15 references.) (ASK)

Presents examples to illustrate that iteration and recursion are useful pedagogical tools that can be used in many areas of mathematics, make models traditionally taught in upper levels accessible in grades 9-14, and provide alternative problem solving approaches less dependent upon ready-made formulas.
