The use of the hand-held calculator for introducing geometric growth is illustrated. The activity is designed for secondary school mathematics students. (MP)

Seven moderately and severely handicapped adolescents (mean IQ = 45) based in a regular middle school were involved in an instructional program designed to teach selected independent supermarket shopping skills. (Author)

Ten factors that can lead to a lack of use or misuse of hand-held calculators in elementary school mathematics are reviewed. (MP)

An unusual alternative starting point for instruction in a beginning calculus course that focuses on Fixed Point Iteration (FPI) is presented. (MP)

A way of exploring the concept of rational and irrational numbers with calculators is outlined. The numbers and routines suggested are designed to lead to additional extensions and provide an area for student exploration. (MP)

Activities geared to reinforcing the skills involved in solving linear equations are given. The material is prepared on worksheets designed for duplication. Student use of calculators is suggested, and the material can aid in promoting mental computation and estimation. (MP)

A study of 46 sixth graders designed to compare the problem-solving performance of pupils using calculators with that of students not using calculators is reported. The argument that calculator availability facilitates problem solving is supported. (MP)

It is suggested that the reasons for teaching the standard written algorithms for calculations are not out of date. Alternative algorithms, such as mental algorithms, calculators, and nonstandard written methods, are discussed. (MP)

Two problems are presented and discussed as a means of demonstrating that the calculator can play a more important role in the mathematics class than simply as a computational tool. (MP)

Describes six crystallographic programs which have been developed to illustrate the range of usefulness of programmable calculators in providing computational assistance in chemical analysis. These programs are suitable for the analysis of x-ray diffraction data in the laboratory by students. (HM)

Three examples are given illustrating the use of the calculator in problems where determining patterns and making conjectures are stressed. (MP)

Citing some past educational fads, the author addresses the curricular opportunities afforded by the hand-held calculator. He argues that students can gain deeper insight into many mathematical concepts by actually experiencing them. The availability of calculators will also cause some topics to disappear from the curriculum. (SD)

A Maryland middle-school teacher can no longer imagine a math classroom without computers, word processing programs, graphing calculators, graphic design programs, and colored printers and monitors. Aided by these devices, her students made great leaps toward the 21st-century technology goals spelled out by the Department of Education in 1995.…

Presents an activity for constructing and solving radical equations which can be done with or without the use of graphing calculators. Highlights one method that two students used to solve radical equations. (ASK)

Presents an experiment to design a precalculus topic that would help prepare students for limits in differential calculus. Emphasizes the topic to enhance the interpretation of graphs and to be applicable in both technology-based and traditional precalculus courses. Uses graphing calculators to help students observe the results of their…
