Analysis of the constraints and potential of the artefact are necessary in order to point out the mathematical knowledge involved in using calculators. Analyzes and categorizes observations of students using graphic and symbolic calculators into profiles, illustrating the transformation of the calculator into an efficient mathematical instrument.…

Argues that the calculator is fallible as a repository of mathematical knowledge. Suggests that the calculator should be considered not only a labor-saving device but a learning device. Provides examples of the use of calculators as a learning device. Contains 16 references. (ASK)

Illustrates the ease with which programs occupying only a single command line of a graphics calculator can be constructed. (MKR)

Explores various emerging technologies for use in the teaching and learning of mathematics and science. Discusses advanced graphing calculators, networked calculators, and participatory simulations. (MM)

This study investigated the effects of using the TI-92+ calculator to demonstrate geometric diagrams to students in class. The participants (N=83) were from three 10th grade classes. A pretest, treatment, posttest with control group design was used in the study. The treatments lasted for 12 weeks. Results from data analyses via the Dependent…

Discusses the appropriateness of lower secondary school students using graphics calculators instead of scientific calculators. (ASK)

University of Chicago School Mathematics Project shares some insights about using new technology, incorporating real-world data and applications into mainstream mathematics, improving student performance, and changing mathematics curriculum. Calculators are easily implemented, particularly high schools. Virtually all students can learn to apply…

Discusses the use of Calculator Based Ranger (CBR) in mathematics classrooms. Provides a classroom activity in which students graph walking in different directions and speeds. Presents student work and testing. (ASK)

Describes the use of an application for TI-83 and TI-92 calculators called the Symbolic Math Guide (SMG) for teaching and learning the laws of exponents in algebra. Discusses ways in which the SMG can be used for teaching, review, and testing. (MM)

Draws on data from a three-year longitudinal study of secondary school classrooms to examine pedagogical issues in using technology resources in mathematics teaching, graphing calculators and overhead projection panels in particular. Theorizes four roles for technology in relation to teaching and learning interactions. Illustrates how technology…

Discusses the benefits of new technologies, especially graphing calculators, in the teaching and learning of mathematics. Presents two activities for teaching algebra and regression using graphing calculators. (ASK)

Suggests a model for the learning and reinforcing of algebraic manipulative skills through the intensive use of group work using computer algebra systems (CAS). Suggests a model for assessing students through group work, for using the TI-92 as a self-assessment tool, and in cross-curricular activities. (Author/ASK)

Explores the broader potential of hand held technology. Presents web resources with descriptions of new technologies and applications that include graphing calculators and classroom communication systems. (MM)

Inquires into assessment items classified as "extended pieces of work" in applicable mathematics in Western Australia. Identifies opportunities for graphics calculator use in extended pieces implemented in schools. Concludes that availability of the technology has widened the scope of approaches used in extended pieces of work in…

Considers the impact of the introduction of graphic calculators into assessment within the International Baccalaureate Diploma. Discusses difficulties that arise in the development of practice questions, how these difficulties were resolved in the questions that appeared on the examinations, and problems of different calculator syntax.
