A proposal for teaching how to graph functions is presented on the basis of the teaching theory of didactical situations implemented by the French author Guy Brousseau. The proposal is aimed at students in 12th grade in high school (USA) or in a freshman calculus course. The TI-92 graphic calculator was used as a teaching aid. (Author/ASK)

While most microeconomics curriculums contain no reference to the use of microcomputers, spreadsheet packages adapt well to microeconomics courses. This presentation examines the following topics in the context of a microeconomics course: (1) The Microcomputer Spreadsheet Package--LOTUS; (2) The Spreadsheet Anatomy--cells, commands, menus; (3)…

Examines four areas of difficulty with graphing and modeling, identifies confusions and misconceptions, and shows how these areas interact in the presence of data-collection devices. (KHR)

Appropriate uses for graphics calculators in precalculus and calculus are discussed. The functions of Casio, Sharp, and Hewlett-Packard brand calculators are stressed. A "Stress Test" for graphics calculators designed to illustrate common errors and to furnish examples of tasks which cannot be completed on these instruments is provided.…

Discussed are the use of spreadsheets for demonstrating and exploring with the whole class, basic and advanced spreadsheet operations, geometric progressions, and graphing. Teacher responses to these methods are described. (CW)

This document gives instructions on how to use a Macintosh computer to create printed materials for mathematics. A Macintosh computer, Microsoft Word, and objected-oriented (Draw-type) art program, and a function-graphing program are capable of producing high quality printed instructional materials for mathematics. Word 5.1 has an equation editor…
