The purpose of this study was to investigate the meanings that a teacher associated with calculators as reflected in the teacher's use of calculators in two 12th-grade mathematics courses, and to link those meanings to the institutions and individuals that supported the development of those meanings. By describing the teacher's conceptions of his…

This paper is designed to show how graphics display calculators can be used to analyze data. The paper describes a classroom activity, where students calculate a linear regression on a data set and answer questions related to the regression. Teaching notes, a full solution, and calculator instructions are included as are blackline masters. (MM)

Which manual calculation skills are still needed when students use graphic/symbolic calculators or computers with computer algebra systems (CAS)? What should students be able to do manually, i.e. just using paper and pencil? This text is the outcome of a two-day discussion on these questions, held by the four authors. Our answers and proposals are…

Advantages and disadvantages of using electronic calculators in the mathematics classroom are discussed; implications for the teaching of mathematics and for the mathematics curriculum are considered. (DT)

Describes a three-step approach for teaching multicomponent distillation to undergraduates, emphasizing patterns of distribution as an aid to understanding the separation processes. Indicates that the second step can be carried out by programmable calculators. (A more complete set of programs for additional calculations is available from the…

Two traditional presentations introducing the calculus of exponential functions are first presented. Then the suggested direct presentation using calculators is described. (MNS)

Describes computer programs (available from authors) including molecular input to computer, programs for quantum chemistry, library orientation to technical literature, plotting potentiometric titration data, simulating oscilloscope curves, organic qualitative analysis with dynamic graphics, extended Huckel calculations, and calculator programs…

Describes computer programs (with ordering information) on various topics including, among others, modeling of thermodynamics and economics of solar energy, radioactive decay simulation, stoichiometry drill/tutorial (in Spanish), computer-generated safety quiz, medical chemistry computer game, medical biochemistry question bank, generation of…

By handling numbers in unexpected ways, computers and calculators create headaches for computer programers and set traps for unsuspecting users by sometimes producing wrong answers. Specific examples of such computer/calculator errors are discussed. (Author/JN)

A hypothetical design optimization problem and technical information on the three design parameters are presented. Although this nested iteration problem can be solved on a computer (flow diagram provided), this article suggests that several hand held calculators can be used to perform the same design iteration. (SK)

Methods for teaching traditional college mathematics materials in the areas of analysis, vector algebra, etc., are reviewed. Examples of interesting and novel construction problems, logical decisions, generalizations with calculators, and other topics used in an experiment at a technical college in Budapest, Hungary are presented. (MP)

A calculator program for a Texas Instruments Model 59 to predict serum theophylline concentrations is described. The program accommodates the input of multiple dose times at irregular intervals, clearance changes due to concurrent patient diseases and age less than 17 years. The calculations for five hypothetical patients are given. (Author/MLW)

Described is the calculator's place in the classroom and its potential for reshaping our computationally oriented curriculum. Activities are suggested for ways calculators can effectively be used to develop four types of mathematical thought. (Author/DS)

Twenty-eight sources on calculators are listed in this partially annotated bibliography. (MK)

The article seeks to illustrate that calculators and problem solving complement each other perfectly. (MK)
