This paper presents two mathematics activities that model functions studied using the Calculator Based Ranger (CBR) software for TI-82 and TI-83 graphing calculators. The activities concern a bouncing ball experiment and modeling a decaying exponential function. (ASK)

This collection of activities is designed to show how TI-Interactive[TM] and Calculator-based Laboratories (CBL) can be used to explore topics in high school science. The activities address such topics as specific heat, Boyle's Law, Newton's Law of Cooling, and Antarctic Ozone Levels. Teaching notes and calculator instructions are included as are…

This paper discusses uses of TI-73 graphing calculators for middle school mathematics students. It indicates that with the appropriate use of the TI-73, students can develop understanding about variables and basic concepts of algebra, and explore mathematical topics. Background on middle school students' difficulties with those subjects is…

The central premise of this study was that the use of graphing calculator technology helped improve students' achievement in upper level biology courses. The populations studied included high school students in a block course entitled "AP Biology/AP Calculus" and students in a traditional AP Biology course. There appears to be a positive effect on…

Hand-held data collection technology allows for access to real-world data collection--at any other time and almost any place. Is the use of data and its collection desirable to the mathematical learning process? The answer is a resounding yes! Not only can significant mathematical ideas be taught in the process; colleagues are also helped in the…

Three examples are presented which involve constructions employing a compass, a centimeter ruler, and a calculator. Employing mathematical tools to support understanding and discovery of mathematical principles is viewed as being clearly a desire of mathematics educators, but it is felt such tools are not frequently used to their fullest.

An approach to equation solving using calculators that promotes the trial-and-error method as a useful strategy when combined with calculators is presented. The approach is specifically geared towards the secondary schools as a way of moving to harder equations that the linear and quadratic ones traditionally used. (MP)

The importance of computational skill for answering items in the quantitative thinking subtest of the Iowa Tests of Educational Development was investigated. Results show that computational skill is not a major factor contributing to the examinee's score on the subtest. (Author/GK)

Forty right-handed high school and college students were trained to operate calculators with their left hands. Results suggest the possibility of improving office machine operating speed, without significant loss of accuracy, by instructing trainees to operate the keyboard with the alternate hand while recording information with the dominant hand.…

The material is designed for student estimation of factors and divisors, with calculator use for checking estimations. Four worksheet masters are designed for classroom use. It is believed that problem-solving skills can be encouraged as students look for ways to improve on estimations. (MP)

Calculators are seen to shift the student focus in problem-solving situations from "how to do it" to "what to do," by keeping computation from standing in the way when pupils write or solve problems. (MP)

Discusses use of computers in Electrical Engineering (EE) at Virginia Polytechnic Institute. Topics include: departmental background, level of computing power using large scale systems, mini and microcomputers, use of digital logic trainers and analog/hybrid computers, comments on integrating computers into EE curricula, and computer use in…

Strategies for incorporating a calculator made within FORTRAN programs and a Response Analysis Scheme during interactive sessions are described highlighting salient features of the programs. (Author/SK)

Ways to make a discussion of the commutative properties of addition and multiplication more interesting to students are reviewed. An alternative promoted is a transposition-of-digits property, seen as useful in a number of instructional situations. The proposed investigation could be structured around calculator use. (MP)

The author recommends allowing elementary students to use pocket calculators, so that they may concentrate on the sense of a math problem without getting bogged down in computation. He presents calculator activities on place value, estimation, and arithmetic operations, suitable for grades 1-6. (SJL)
