Presented are instructions for activities in which a calculator is used to investigate algebraic concepts. Also presented are short computer programs involving topics taught in prealgebra and an activity in which a trapezoid is transformed into a circle. (JN)

The outcomes of a conference on computing in school mathematics, held in March 1984, are summarized. Recommendations on curriculum, instruction, and teacher education are included. (MNS)

This report of a March 1984 conference presents recommendations on technology and curriculum at the elementary, middle school, and secondary school levels; instruction; and mathematics teacher education. (MNS)

Ignored concepts of numbers, notation, and operation with rational numbers are described. It is proposed that these be taught in the time now devoted to paper-and-pencil skills made obsolete by calculators. (MNS)

Imaginative ways of using calculators to explore decimal fractions with secondary school and some middle school students are given. Four explorations on terminating and repeating decimals, the length of periods, and relationships are described. An appendix presents mathematical proofs. (MNS)

This article provides checklists designed to help educators select an appropriate minicalculator for their individual or groups situation. (DT)

A number-word puzzle to be solved by using a calculator is presented. (DT)

Geometry is an important branch of mathematics. Geometry curriculum can be enriched by using different Technologies such as graphing calculators and computers. Logo-based different software packages aim to improve conceptual understanding in geometry. The goals of this paper are i) to present theoretical foundations of any computer software…

The increasing availability of computer algebra systems (CAS) for the high school classroom is expected to have a significant effect on how algebra is taught, when it is taught, and the expected learning types. This paper reports on a computer algebra approach to the teaching of algebra to 13-16 year old students in a high school in Melbourne,…

This project description is designed to show how graphing calculators and calculator-based laboratories (CBLs) can be used to explore topics in physics and health sciences. The activities address such topics as respiration, heart rate, and the circulatory system. Teaching notes and calculator instructions are included as are blackline masters. (MM)

This paper reports on a mathematics course in an Austrian high school that focuses on probability distributions. Students in this course used a TI-92 during math classes, at home for doing exercises, and during math tests. The TI-92 was used as a tool for calculations and illustrations making the concepts of probability distributions easy to…

This paper introduces a teaching unit on using spiral symmetry in a geometry course for secondary education majors. The TI-92 graphing calculator is used to exploit the exponential function to analyze the geometric topic of similarity and to study the derivative of spirals. The paper provides some procedures and programs to generate spirals using…

This study explores a program designed to revolutionize developmental mathematics at the college level using the new handheld computer algebra systems and new information about the ways in which students learn mathematics. Students in one class of developmental algebra worked with the new approach to learn algebra by building on their intuitive…

The purpose of this study was to investigate the effects of the Casio 9850 and the TI-85 graphing calculators on college students' procedural skills and conceptual understanding in two different developmental mathematics courses. The courses used in this study were Elementary Algebra and Intermediate Algebra. Both the non-graphing calculator group…

This paper discusses how students' participation in conversation and classroom activities potentially evidences and constitutes their cognition. Participation is viewed in terms of reflective discourse, a construct from the literature, and is described in the context of two Year 11 students together designing a simple aplet for their graphics…
