Refinements of work with calculator algorithms previously conducted by the author are reported. Work with "chaining" and the doing/undoing property in addition and subtraction was tested with 24 third-grade students. Results indicated the need for further instruction with both ideas. Students were able to manipulate the calculator keyboard, but…

The purpose of this study was to compare the effects of a fourth-grade arithmetic sequence based on calculator flow-charting with those of traditional textbook instruction. Both achievement and attitude were compared. Students were matched on the basis of intelligence (Otis Quick-Scoring Mental Ability Beta Test Form EM) and sex, and then randomly…

These worksheets deal with sums of numbers. Students are asked to find the relationship between the last number in the series, the number of addends, and the sum. (MP)

Describes a hand held calculator exercise for computing the Rydberg Constant accurately. (SL)

An attitude survey and arithmetic tests were given to samples of students in order to quantify the benefit obtained from their use of calculators. Results showed that the use of the calculators does improve students' arithmetic performance with the less able students showing about twice the improvement of the more able. (MN)

A program involving the use of calculators for an eighth-grade class is described. Guidelines to assist those in the process of initiating a program involving the use of calculators are included. (MN)

Provides examples from advanced secondary school science which are amenable to the use of a programmable calculator. Compares the use of the calculator to a computer terminal. (CP)

Geometry and a hand-held calculator are used to find a value of pi accurate to five decimal places. (CP)

The authors propose that electronic calculators can be perceived as function generators rather than mere computational aids and can be used to investigate function concepts such as domain, range, composition, inverse, correspondence and so on. (MN)

An elective course aimed at giving tenth-grade students some experience with practical arithmetic problems is outlined. The two-week course is designed primarily for students who will be leaving at the end of the year and includes topics such as calculators; earning, spending, and saving money; tax; and buying a car. (MN)

Describes the calculation of the potential of the Earth's gravitational field strength and the energies of satellites in orbit round the Earth with a programmable pocket calculator. (SL)

Reports results of a student attitude survey among junior high school students who had been allowed to utilize classroom calculators to check results of mathematical computations. Students displayed a significant preference for using calculators in the classroom. (SL)

Using calculators (and computers) to develop an understanding and appreciation of statistical ideas is advocated. Manual computation as a prerequisite for developing concepts is negated through several examples. (MNS)

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

Research indicates that calculators can promote mathematics achievement. Some topics with which calculators can aid are briefly discussed: problem solving, number ideas, counting, basic facts, and computation with whole numbers and decimals. (MNS)
