Presents a method for introducing students to broken-line functions with unbroken domains. Concludes that a unit on broken-line functions should enhance students' understanding of the function concept. (ASK)

Offers a real problem for students with younger siblings that uses a board game and illustrates the use of modeling and simulation. (ASK)

Presents a hands-on modeling experiment that focuses on hyperbolic functions, asymptotes, data analysis, applied statistics, and optimization problems. (ASK)

Demonstrates that the equation of a circle (x-h)2 + (y-k)2 = r2 with center (h; k) and radius r reduces to a quadratic equation x2-2xh + (h2 + k2 -r2) = O at the intersection with the x-axis. Illustrates how to determine the center of a circle as well as a point on a circle. (Author/ASK)

Describes an experiment with two participants, one of which is familiar with the Geometer's Sketchpad but not with Cabri-Geometre and vice versa. Displays the work of both participants when they are given two geometry problems in secret and 20 minutes to work on each, the first with software that they are familiar with and the second using the…

Presents two problems whose solutions can be enhanced using the Geometer's Sketchpad to solve the problems. Concludes that available computer technology can aid in the analysis and solution of some interesting geometry problems. (ASK)

Explains how geometric constructions can enrich students' visualization and comprehension of geometry. Presents examples of geometric constructions that students can construct using the Geometer's Sketchpad. (ASK)

Describes a lesson designed to teach the probabilistic topics of permutation and combinations in a constructivist manner. (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. (Author/MM)

Part of a series exploring how mathematics is used in the workplace. Software developers and statisticians record data of hockey games and players using statistics accessible to middle school students. (MM)

Describes a project that utilizes journal writing in the mathematics classroom. Journals are a valuable form of assessment for students and teachers and furnish concrete feedback on a student's understanding of a mathematical concept. (ASK)

Presents a mathematics lesson that focuses on particular connections between geometry and measurement, how change in shape effects the area of the interior region of parallelograms with the same perimeter. (ASK)

Uses the available data about the Titanic's passengers to interest students in exploring categorical data and the chi-square distribution. Describes activities incorporated into a statistics class and gives additional resources for collecting information about the Titanic. (ASK)

Encourages students to use reasoning and quantitative problem-solving skills to discover the solution to an important practical problem related to absolute-value function and statistical median. (ASK)
