This study was an attempt to provide some evidence on the effects of calculator usage with primary-age children. Specifically, the study compared the performance of children who had access to calculators for an extended period of time, and whose teachers used calculators in specified instructional ways, with children who did not have access to…

An activity unit is presented in which the minicalculator is used in determining the student's paces or steps per kilometer and their measuring distances. (MN)

The objective were to explore some of the ways in which the calculator can be used and to determine the effects. Areas covered are: computation, mathematics readiness, problem solving, and discovery learning. (MP)

This bibliography lists books containing classroom-ready materials that can be used in conjunction with routine mathematics lessons. A description is given of six of these books. (MP)

Results are given of a 14-question survey of students related to the use of calculators in school. The use of mathematical tables as opposed to calculators is discussed. (MP)

Describes a novel approach to the computation of probability contours with the use of a pocket calculator. (CP)

A grouping procedure which systematically combines objects to satisfy a criterion specified by the investigator and groups those objects that are most alike first is discussed. Two such methods that can be easily demonstrated in the classroom setting with the aid of electronic calculators are presented. (MN)

A hand-held calculator is used to explore several easy and interesting mathematical topics involving compound and continuous interest suitable for beginning college students. (MN)

The use of calculators in mathematics classes of eight-year-olds was investigated. Results showed that the experimental classes were quicker and more accurate in addition, subtraction, and multiplication than the control classes at the end of the year. (MN)

A method for approximating the nth root of any positive number that requires only a four-function calculator with a square-root key and repeat multiplication capability is given. (MN)

A brief account of the controversial arrival of the use of the electronic calculator in schools and examinations in Scotland is given along with suggestions for future calculator usage. (MN)

A calculator activity, described as a bingo game, emphasizes speedy calculations as well as problem solving. (JT)

Calculators in school need not cause decline in either practical skill or mathematical understanding. And with the right curriculum materials, they can help bring about major improvements in mathematics education. (Author)

For an entire school year, 24 seventh-grade classes were taught problem-solving strategies; in 14 of these classes the instruction was supplemented by calculators. Mixed findings resulted for both problem solving and calculator use. (MNS)

A special issue highlights projects in some of the 130 school districts that make up the Technology Leadership Network, a group founded by the National School Boards Association in cooperation with state school board associations. The name, address, and telephone number of a contact source accompanies each program description. (MLF)
