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…

Presents an integrated exposition of aspects of secondary school mathematics and a medical science specialty. Reviews clinical medical practice and theoretical and empirical literature in mathematics education and radiology to develop and pilot model integrative classroom topics and activities. Suggests mathematical applications in numeration and…

Presents attributes of different types of software including Logo, geometric packages, graphical packages, and spreadsheets, each of which offers different opportunities for learning. Investigates the different ways in which the software allows for performing the given task so as to make the mathematics of the task explicit to users. (KHR)

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)

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

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)

Addresses the "T-cubed" or Teachers Teaching with Technology program and their courses utilizing hand-held technology such as graphic calculators, data-loggers and the TI-92 hand-held computer. Describes practical experiments involving discharge, a temperature probe, and an oscillating water sprinkler. (AIM)

An activity that shows how mathematics can be used to model events in the real world is described. A way to calculate the area of the sun covered by the moon during a partial eclipse is presented. A computer program that will determine the coverage percentage is also included. (KR)

Describes how to use the computer algebra system (CAS) Mathematica to analyze projectile motion with and without air resistance. These experiments result in several conjectures leading to theorems. (Contains 17 references.) (Author/ASK)

Presents some activities for both art and mathematics classrooms. Traces the history of geometric art and focuses on a way of drawing tiling using LOGO programming. Describes some of the work on tessellations by the mathematician Roger Penrose and the artist M.C. Escher. Provides websites for further information. (KHR)

Offers a cave-mapping problem and discusses how to solve it. Presents the problem and necessary geologic background and a spreadsheet algorithm to solve the problem. (KHR)

Describes how to draw lines in centimeter units on a computer monitor with the Logo program. Presents four activities involving drawing geometric shapes. Provides a program to move a turtle slowly. (YP)

Presents a game in which if player is playing a match of this game with an opponent, at each step in the game he has to decide whether to continue or to stop. Helps students to develop a strategy for making such a decision based on the expected gain and related probabilities. (Author/ASK)

While functions and relations are important concepts in the teaching of mathematics, research suggests that many students lack an understanding and appreciation of these concepts. The present paper discusses an approach for teaching functions and relations that draws on the use of illustrations from database management. This approach has the…

Describes a series of activities in which students collect data on personal information and interests and use them to create a database file. Constructing a database gives students the opportunity to satisfy their natural curiosity and use numbers as they make predictions, develop number and operation sense, and explore data, fractions, and…
