Describes features and uses of the Geometry Forum, a National Science Foundation funded Internet project which includes a set of electronic newsgroups for people interested in geometry. (MKR)

Presents ways that teachers can gain free or low-cost access to the international electronic network known as the Internet. Discusses activities in British Columbia, Delaware, Florida, Illinois, Kentucky, Maryland, Massachusetts, Minnesota, Missouri, Nebraska, Newfoundland, New Mexico, Ohio, South Carolina, South Dakota, Texas, and Virginia. (MKR)

Presents mathematics problems which use technology for exploring and verifying relationships among data sets; comparing and analyzing effects of changes in parameters of mathematical models; simulating complex, expensive, or dangerous events using probability models based on random outcomes; and graphically or numerically zooming in on apparent…

Describes the use of spreadsheets to discuss mathematical concepts without using algebraic notation. Presents examples using Fibonacci numbers and factorials. (MKR)

Presents a real-life example of mathematical modeling in which a medical company asks for help in solving a warehouse-inventory problem. Uses charts, graphs, and computers. (MKR)

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)

Chronicles an example of using the Internet to teach high school statistics. The project, Ask a Teen, involved a group of students who surveyed and shared cultural data with a group of overseas students. Includes sample survey questions. (MKR)

Examines research relevant to the debate about the relative emphasis that formal proof should play in high school geometry. Discussion includes establishing truth in geometry, research in students' learning of proof, developing the notion of proof, alternatives to axiomatic approaches, computer construction programs, and classroom recommendations.…

Discusses several dynamic geometry constructions with rectangles. Advocates use of software like Geometer's Sketchpad and Cabri Geometry for fostering fresh insight into traditional geometric theorems. Illustrates problem-solving methods not possible with pencil and paper. (MTE)

Discusses the use of the recursive method to permutations of n objects and a problem making c cents in change using pennies and nickels when order is important. Presents a LOGO program for the examples. (YP)

Describes a project using computer and video technology to help students understand the criteria that were used to evaluate their statistics projects. (MKR)

Describes a classroom activity in which students explore a real-life application of algebra by sending secret messages to each other. (MKR)

The question "What shape will have the largest area for a given perimeter?" identifies an important relationship between area and perimeter that has long been intuitively realized in many cultures. Historically, numerous cultures have made use of this relationship between area and perimeter when struggling to build dwellings with shapes…

Discusses the use of software created for practical, real-world applications to connect mathematics to other subjects and to the world outside the classroom. Software presented includes Design Your Own Home, Bridgebuilder, Physics Explorer, Aldus Superpaint, and Sprout. (MKR)
