Presents a mathematics problem on how a sailor decides the shortest distance between two points by using a calculator. (ASK)

Presents an activity that utilizes a digital camera to capture a stream of water from a faucet to study quadratic behavior using graphing calculators. (ASK)

Asserts that there are numerous advantages to using graphing calculators, including the teaching of higher-level thinking skills and allowing students to draw conclusions about what they are learning. However, mathematics educators face such challenges as teaching students when it is appropriate to use graphing calculators, course-content…

Presents graphing calculator activities that rely on resolving the magnitude and direction form of vectors into their Cartesian components so that they are suitable as applications for vector or trigonometric relationships for years 10-12. (ASK)

Describes two activities that involve thinking of slope as rate of change. Uses a calculator-based laboratory, graphing calculator, appropriate probes, and web sites to make the concepts of slope and y-intercept come alive for middle grade students. (ASK)

Reports on a research study that examined how some teachers used graphing calculators in their instruction of mathematics, and how their views of mathematics were manifested in the ways in which they chose to use this technology. Suggests that teachers used graphing technology as an extension to the way they always taught the unit. Contains 23…

A current project for the Allegany College of Maryland Mathematics Department is using spreadsheets in some of their General Education Mathematics courses. It is important to note that one of the key features of this project is that is does not require an introductory computer course as a prerequisite for any of the mathematics courses that will…

Technology is evolving and now some secondary classrooms see students using computer algebra systems (CAS), however, Zbiek (2003) points out that "graphical representations seem to abound in CAS-using classrooms" and "many [research] studies of the use of CAS depend highly on the graphing component of the tool". Kissane (2001) suggests that with…

In his recent article in this journal, John Gough (2004) concludes that the practical results of the considerable academic research undertaken at the University of Melbourne into the uses and impacts of graphics calculators and CAS (computer algebra systems) should be made more widely available in journals for teachers. This short article is…

This author's mission was to try out some materials being developed by a member of an advisory team, and give feedback about how they worked in the classroom. She was provided with detailed lesson plans, including mental and oral starters, and a list of resources. Her objective was to explore and interpret collected data using ICT in order to draw…

This article presents several activities (some involving graphing calculators) designed to guide students to discover several interesting properties of Fibonacci numbers. Then, we explore interesting connections between Fibonacci numbers and matrices; using this connection and induction we prove divisibility properties of Fibonacci numbers.

Assumptions: Today, when technology has taken its place in almost all classrooms in schools and colleges across the country, there is a need to know how technology "influences the mathematics that is taught and enhances students' learning" (NCTM, 2000, p. 24). Rationale: This presentation describes qualitative study which purpose was to…

This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…

This book is designed to supplement The University of Chicago School Mathematics Project's (UCSMP) Transition Mathematics textbook. The content and questions in this book have been sequenced to specific geometry lessons in the Transition Mathematics text. All geometry explorations are done with the TI-92 calculator. This book is organized around…

Algebra students typically pay little attention to choosing appropriate domains, ranges and scales of axes for graphing functions. The purpose of this study was to investigate the effect of introducing an assignment and employing the graphing calculator to examine and alleviate students' difficulties regarding the selection of appropriate domains,…
