A research experiment is described in which the effect of the availability and use of a calculator on seventh graders' mathematics achievement was investigated. Preliminary findings on parental attitude toward the use of calculators and on student achievement are discussed. (DT)

A proposal that the fullest possible use be made of calculators at all grade levels is discussed. (DT)

Calls for greater emphasis on knowledge of computers and other electronic devices in order to prepare students for the rapidly developing technological changes in society. (JY)

This paper reports on a workshop developed to give middle school teachers experience using the TI-73 calculator as a teaching tool and to serve as a model for the introduction of technology into their classrooms. A booklet prepared for the workshop gave keystrokes used for the TI-73 with an emphasis on features that are unique to this calculator.…

How does your calculator quickly produce values of trigonometric functions? You might be surprised to learn that it does not use series or polynomial approximations, but rather the so-called CORDIC method. This paper will focus on the geometry of the CORDIC method, as originally developed by Volder in 1959. This algorithm is a wonderful…

This essay describes the role of graphing calculators in mathematics reform. Among the topics discussed are the history of graphing calculators in mathematics education, recent technological innovations, and professional development opportunities. The case is made for a balanced approach between calculator use and paper-and-pencil techniques.…

This book is designed to familiarize instructors and students with the Texas Instruments Explorer Plus calculator and provide background information and activities for including the calculator in the mathematics curriculum. Materials are included for three workshops and 26 lessons. Lessons are organized by common mathematical topics making it…

The Educational Testing Service studied the status of calculator use in high school classrooms. Responses were received from 4,568 high schools. Thirty-eight percent of those who were mailed a survey participated, and 12% of those who received e-mail invitations responded. Results indicate that the prevailing policy in U.S. high schools is to…

This collection of activities is designed to show how graphics display calculators can be used to explore pentominoes and tangrams. Activities include games and puzzles developing spatial relations. Teaching notes, solutions, and calculator instructions are included as are blackline masters. (MM)

This document presents keystrokes for the Texas Instrument (TI-83) graphing calculator. After presenting some basic TI-83 keystrokes, activities for student practice are listed. This is followed by keystrokes for TI-83 advanced functions such as evaluating function values, finding the zero of a function, finding the intersection of two graphs,…

In this age of digital technology, calculators, computers, and educational software, calculator-based laboratories have become important elements in the learning and teaching of mathematics. This digest provides an annotated listing of World Wide Web resources and contact information for organizations pertaining to technology use in mathematics…

The purpose of this study was to investigate the meanings that a teacher associated with calculators as reflected in the teacher's use of calculators in two 12th-grade mathematics courses, and to link those meanings to the institutions and individuals that supported the development of those meanings. By describing the teacher's conceptions of his…

This paper is designed to show how graphics display calculators can be used to analyze data. The paper describes a classroom activity, where students calculate a linear regression on a data set and answer questions related to the regression. Teaching notes, a full solution, and calculator instructions are included as are blackline masters. (MM)

Which manual calculation skills are still needed when students use graphic/symbolic calculators or computers with computer algebra systems (CAS)? What should students be able to do manually, i.e. just using paper and pencil? This text is the outcome of a two-day discussion on these questions, held by the four authors. Our answers and proposals are…

Advantages and disadvantages of using electronic calculators in the mathematics classroom are discussed; implications for the teaching of mathematics and for the mathematics curriculum are considered. (DT)
