Presents an experiment in which a programmable calculator is employed as a data generating system for simulated laboratory experiments. The example used as an illustration is a simulated conductimetric titration of an aqueous solution of HC1 with an aqueous solution of NaOH. (Author/EB)

The purpose of this study was to investigate the effects of the use of hand-held calculators on the teaching of decimal arithmetic in seventh and eighth grade pre-science units. In particular, the effects of calculators on pencil and paper computational skills and on conceptual understanding were studied. The study consisted of a pre-unit…

A study designed to serve as an initial step in building a theory of computer literacy was conducted to provide new information concerning how humans think about calculators and to determine how individual differences in students' intuitions affect their understanding and use of the calculator. Thirty-three expert and 33 novice calculator users…

Investigating properties and characteristics of unary operations is shown to be facilitated by using calculators. Several avenues for instructional exploration are suggested and examples given. These include questions relating to relations, inverses, commutativity, distributivity, and iterations. A discussion of the calculator algorithm for…

Several examples are given of a variety of nonstandard problems, not ordinarily found in texts or courses, now accessible to students who have programmable calculators. These include: (1) finding limits; (2) evaluating infinite series; (3) calculating finite series; (4) computing variable length products; (5) solving equations; (6) searching for…

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)
