Defines psychic intelligence as an inclination all children possess to use whatever cognitive intelligence they have for learning, adaptive behavior, and pleasure; strongly suggests that algorithmic drill usually damages the mentality of children by stifling psychic intelligence; and discusses the use of pocket calculators to prevent this effect.…

Presents activities to help teachers use the calculator. The type of logic, keystroke errors, and the constant are each discussed. (MNS)

Using the calculator to do addition and multiplication in base 2 is discussed, with the stress on how to change numbers from one base to another using the calculator. (MNS)

The use of the calculator is considered from a functional view and from a pedagogical view. (DT)

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…
