Outlines an attempt at integrating web-based activities into a precalculus course at a large university in which discussion of the development of the activities is initially provided. Investigates the effects of the use these activities in four classrooms. Focuses on the use of the activities by two instructors, only one of whom received…

Illustrates how to connect mathematics to real-world problems. Describes the calculator-based laboratory system which collects data from the real world and transfers it to graphing calculators. Presents an activity that emphasizes elliptic integrals. (ASK)

Presents an experiment to design a precalculus topic that would help prepare students for limits in differential calculus. Emphasizes the topic to enhance the interpretation of graphs and to be applicable in both technology-based and traditional precalculus courses. Uses graphing calculators to help students observe the results of their…

This paper documents how eight high school students in a precalculus class enhanced with graphing calculators think about functions. Three models of thinking about functions emerged from students' function images observed over a period of 9 months. In the graph model, students believed that functions are essentially graphs; in the equation model,…

Describes an experimental study in which two sections of calculus were taught using the same materials, except one section was enhanced with the computer algebra system Mathematica. Results indicated that the students in the technology group had advantages to understanding certain key topics in calculus such as limits, derivatives, and curve…
