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)

Students have difficulty associating equations of vertical and horizontal lines with their respective graphs. Presents an activity using a TI-82 graphing calculator to eliminate this confusion and to strengthen students' understanding. (ASK)

Explores how the use of the graphics calculator may lead to changes in students' solution approaches and how these changes affect student achievement. Concludes that only prolonged use of the graphic calculator leads to enrichment of the solution repertoire of students and a better understanding of functions. (Contains 11 references.) (Author/ASK)

The graphing calculator affords the student in analysis a powerful tool to extend visualization, which was previously limited to textbook illustrations and time-consuming constructions. Provides illustrative examples used in initial classroom presentations of several topics including convergence and in student explorations of these topics. (ASK)

Presents a study in which three classes of grade 10 students worked with graphics calculators throughout, five classes used them for approximately two months, and four classes did not use them at all. Posttest results showed that students who had worked with graphics calculators tended to attempt more problems and obtain higher test scores than…

Presents three geometric problems from a workshop for in-service algebra teachers to help them make connections between the mathematical concepts that they know and the drawings that they were required to display on their graphing calculators. (ASK)

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)

Using a Computer Algebra System (CAS) to help with the teaching of an elementary course in linear algebra can be one way to introduce computer algebra, numerical analysis, data structures, and algorithms. Highlights the advantages and disadvantages of this approach to the teaching of linear algebra. (Author/MM)

Reports the results of a qualitative, classroom-based study on the interactions between the role, knowledge, and beliefs of the teacher; the mathematical tasks; and the patterns of graphing calculator use by a group of pre-calculus students. Describes the development of a set of norms that governed the ways in which the tool was used in the…

Describes the five-year evolution of a multi-sectioned precalculus course for business and health professions majors at the University of Hartford. Concludes that students have benefited from the revised course that uses the graphing calculator, calculator-based laboratory (CBL), and group work. (ASK)

Describes the use of a graphing calculator-based laboratory (CBL) device that provides a portable data-collection system that students at high school and college levels can use to conduct projects in chemistry. Reviews possible uses for CBL in a chemistry program. (Author/CCM)

Uses the average-monthly-temperature function as an application of the sine wave. Argues that the attractive aspect of gas bill graphs is that they clearly illustrate that sinusoidal curves are useful and meaningful in an everyday context. (ASK)

In a classroom environment in which continual access to graphing calculators is assumed, items that have been used to assess students' understanding of functions often are no longer appropriate. Describes strategies for modifying such items including requiring students to explain their reasoning, using calculator-active items, analyzing graphs and…
