Fourteen topics are discussed that need to be included in the curriculum to make it possible for students to successfully take full advantage of the calculator and its capabilities. These include: underflow, overflow, estimation, scientific notation, powers of ten, rounding, and truncation. (MP)

Students in three mathematics classes were assessed on two aptitudes, field independence and general reasoning, and randomly assigned to either an expository or a discovery treatment. The expository treatment used a deductive sequence of instruction and provided maximal guidance for the students. The discovery group used an inductive sequence with…

A method is given for obtaining a fairly accurate table of common logarithms, elementary arithmetic, and linear interpolation. The author recommends the use of a calculator. (Author/MN)

Illustrations are provided which show how some algebraic manipulations done prior to doing calculations can eliminate unnecessary storage of data, reduce the total number of needed steps, and avoid overflow. (MN)

Teachers and administrators are urged to develop a system-wide policy on the use of the calculator in the classroom. Questions to be considered in the process are listed. (JT)

The use of the programmable calculator is discussed for obtaining numerical solutions to equations. The program is listed and the method illustrated. (MP)

A game for the HP-25 programable calculator is discussed. The objectives of the game are to introduce angle measurement and the rudiments of trigonometry. A program for the game is given. (MP)

A computer program is presented that generates problem sets involving sketching graphs of trigonometric functions using graphical addition. The students use calculators to sketch the graphs and a computer solution is used to check it. (MP)

Described is the use of calculators in two experiments. In the first, students determine the relative atomic mass of magnesium. In the second, students use a calculator to determine a constant for gaseous concentrations of two reactants and the product at equilibrium. (AJ)

This article describes techniques which enable the user of a comparatively simple calculator to perform calculations of cube roots, nth roots, trigonometric, and inverse trigonometric functions, logarithms, and exponentials. (DT)

Impressions are recorded of several aspects of the International Congress on Mathematical Education. The program, curriculum development, calculators and computers, goals for teaching mathematics, and preservice elementary teacher education are briefly discussed. (DT)

The relative effectiveness of three methods of teaching fraction computation in the context of the community college was investigated. The use of calculators was a special focus of the study. The three methods were: (1) conventional algorithms with no calculator, (2) conventional algorithms with calculator, and (3) alternative algorithms using…

Discussed are the difficulties that entering college freshmen seem to have with mathematics, particularly with fractional forms. A success-oriented program is suggested in which all students are successful. To obtain this goal, a number of alternative routes are discussed such as presenting decimals before fractional forms and the use of the…

The calculator is used to obtain values for use in graphing curves. Three worksheets are included. (MP)
