Presents the Fibonacci sequence in a format that is readily implemented using the table and list features of the Texas Instruments TI-82 graphing calculator or a spreadsheet. Includes questions and investigations that can be explored using these tables and lists. (MKR)

Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

It is proposed that teachers can exploit the calculator function of a standard microcomputer word processor to create an electronic gradebook. A method is described for computing overall evaluations from component grades of different types and weights on a word processor to instantly calculate the composite for each student at desired intervals.…

Calculator riddles can interest elementary students in math. Solving riddles where a numerical answer turned upside down reveals a word answer provides an amusing way to practice mathematical operations and learn about calculator functions. The paper explains how to create word riddles and includes student work pages. (SM)

Uses a graphing calculator to show examples of misrepresentations of periodic functions to help increase student interest and explore mathematical relationships. (MKR)

Discusses ways to present mathematics concepts dealing with the ellipse to high school students, particularly by using a graphing calculator. Real-world occurrences of ellipses are considered, and a one-page student worksheet on constructing an ellipse is included. (LRW)

Focuses on changes in attitude toward mathematics and calculator use and changes in how general mathematics students naturalistically solve algebraic problems. Uses a survey to determine whether a student is rule-based. Concludes that the rule-based students used an equation to solve the algebraic word problem whereas the non-rule-based students…

Presents an activity that uses graphing calculators to duplicate the curves generated by a Spirograph, a design-generating drawing toy. (ASK)

One way to assist students in developing correct intuitive ideas about the effect of sample size is to allow students to simulate similar problems. Describes experiences with classes performing simulation using graphing calculators. (ASK)

Shares observations on the use of graphing calculators based on anecdotal evidence and conversations with teachers in the United States. Compares these issues according to U.S. and Australian educational systems. Discusses the acceptance of calculators into the U.S. educational system, teacher expertise levels, and equity issues. (ASK)

Describes students' written answers that seemed technology-assisted in the 1999 Calculus Tertiary Entrance Examination (TEE). Illustrates how in the 1999 Calculus TEE some students used their calculators in flexible ways. (ASK)

Students can learn to make algebra, trigonometry, and geometry work for them by using matrices to rotate figures on the graphics screen of a graphing calculator. Includes a software program, TRNSFORM, for the TI-81 graphing calculator which can draw and rotate a triangle. (MKR)

Describes a lesson that outlines a statistics/probability investigation into some aspects of past performance in snooker (a billiards game) using the random number generator on a graphing calculator. (MKR)

Presents activities in which students are invited to re-create on their calculator screen images using graphical features of the graphing calculator. (ASK)

Presents an inquiry into students' conceptual development of a graphics calculator function for direction. Discusses reflective thinking and reflective enculturation, operational and structural understanding, and situated abstraction. (Contains 33 references.) (Author/ASK)
