The purpose of this study was to determine teachers' views of learning algebra and to investigate if any relationship exists between their views of learning algebra and the ways that they use graphing calculators in their algebra classes. The 48 algebra teachers who participated in the study were from Allen, Putnam, and Van Wert counties in…

This paper discusses TI-89 and TI-92 graphing calculators as a tool for teaching mathematics. How this technology is likely to affect the teaching of mathematics and the role of technology in general is described. Discussion begins with a comparison of two areas, mathematics and moving/transportation, from a technological aspect, and focuses on…

Looks at the possible impact minicalculators will have on education and considers their main features. (Author/DN)

The general algorithm used in most hand calculators to approximate elementary functions is discussed. Comments on tabular function values and on computer function evaluation are given first; then the CORDIC (Coordinate Rotation Digital Computer) scheme is described. (MNS)

Presented is a program written for an HP-25 programmable calculator. It will aid in the effective impedance of a series-parallel network containing both reactive and resistive elements. (MNS)

Describes a program written for a programmable pocket calculator that computes the frequency response of linear systems. (Author)

Student access to programmable calculators and computer terminals, coupled with a familiarity with baseball, provides opportunities to enhance their understanding of the binomial distribution and other aspects of analysis. (MP)

This short quiz for teachers is intended to help them to brush up on their calculator operating skills and to prepare for the types of questions their students will ask about calculator idiosyncracies. (SJL)

Nine principles concerning calculators are identified and discussed. (DT)

Presents activities for teaching the logistic growth model using calculators and spreadsheets. (ASK)

Describes how the introduction of the TI-92 transformed a traditional first semester linear algebra course into a matrix-oriented course that emphasized conceptual understanding, relevant applications, and numerical issues. Indicates an increase in students' overall performance as they found the calculator very useful, believed it helped them…

Explains a teacher's rationale for the use of calculators in the classroom and a take-home page to help parents understand the importance of calculators. (YDS)

The values of a polynomial with integer coefficients can be computed using a graphing calculator, but it is impossible to see the formula itself. Suggests finding this formula from numerical data and describes the unusual way to solve this problem with one calculation only. (Author/NB)

Uses cryptography to demonstrate the importance of algebra and the use of technology as an effective real application of mathematics. Explains simple encoding and decoding of messages for student learning of modular arithmetic. This elementary encounter with cryptography along with its historical and modern background serves to motivate student…

What initially appears to be a standard maximum-minimum problem presents, with a particular independent variable, a wealth of calculus and algebraic subplots. Uses graphing calculator technology to reinforce the "pencil and paper" solution and open the problem to lower level mathematics courses. (Author/NB)
