Handheld computers, sometimes known as PDAs, have been available for purchase since the mid-1990s, as have their handheld relatives, the graphing calculators. It is only in the past few years, however, that these diminutive devices have made their way into K-12 schools in numbers significant enough to allow us to draw conclusions about their…

Discusses the interconnection among the various modes of the TI-92 calculator (geometry, data graphing, function graphing, and algebra) and how the power of visualization is extended to provide multiple approaches to complex problem situations. Provides a graphing problem with illustrations and results. (AIM)

Presents an activity devised as a method of introducing periodic functions that can enable students to gain a deeper understanding of the concept of function. Employs a calculator-based laboratory, a light sensing probe, and an appropriate calculator. Calculator programs and sample data are included. (DDR)

Asserts that graphing calculators give students and teachers the ability to investigate, explore, compare, and discover concepts in a much more comprehensive way than simple calculators or no calculators at all. Offers specific examples that illustrate the advantage of graphing calculators in the Montessori middle school classroom. Lists three…

Discusses how applications from microbiology and sociology can be used to involve students. Presents a physical context for critical concepts in a first-semester calculus course. (Author/ASK)

Technology offers tools and information that students need to explore real-world mathematical connections and investigate questions reflecting their own interests. This article illustrates how students can use technology to gather and interpret information, perform descriptive and graphical analysis, make statistical predictions, and create and…

Illustrates how graphing calculators can be used to address the knowledge and skills promoted by the National Council for the Social Studies (NCSS) and other educational organizations. Focuses on plotting capability and facilitating various types of data and information analysis. (CMK)

Presents a program in the United Kingdom that trains every serving teacher and trainee teacher how to use Information and Communication Technology (ICT) to teach their subjects more effectively. Discusses mathematics education related to this part of the program. (ASK)

A study compared the performance of rural and urban Western Australian students on the college-entrance mathematics examination following introduction of graphics calculators. Although urban students scored higher than rural students in the 3 years studied, the gap remained relatively consistent, indicating that rural students were not further…

This paper recounts the experiences of eighteen student teachers who used graphics calculators to teach mathematics in secondary schools. As part of their formal assessment, they submitted twenty accounts, listing the problems and benefits they had encountered in the course of using this technology. These accounts are analysed in terms of the…

High school algebra and geometry teachers use graphing calculators extensively in their classes today. National and state mathematics curriculum standards recommend their use for class work, tests and assignments. Because of recent legislation, including "IDEA 2004" and "No Child Left Behind", most students with mild…

This research focuses on the graphics calculator in calculus and its impact on students' abilities to work with graphical, numerical, and symbolic representations. Three courses are compared, two of which are taught with less emphasis on the use of graphing calculators. The format of the course emphasizing calculator use is more traditional than…

This article focuses on three key factors that a survey of literature indicated impact the teaching and learning of mathematics with graphing calculators: access to graphing calculators, the place of graphing calculators in the mathematics curriculum, and the connection between graphing calculators and pedagogical practice. Access to graphing…

Equivalence of algebraic expressions is at the heart of transformational work in algebra. However, we know very little about students' understanding of equivalence. This study is part of a larger project that explores the use of CAS as a didactical tool for promoting both technical and conceptual growth in high school algebra with tasks specially…

This paper presents learning tasks of a new type that are made possible by dynamic geometry software and discusses reasons why it takes time for teachers to design and use such tasks. The paper is divided into four sections: (1) The Spatial and the Theoretical; (2) Tasks in Dynamic Geometry Software Fostering the Learning of Geometry; (3) The…
