An algorithm for the calculator is given for determining the day of the week for any date. An instructional sheet, a worksheet, and a BASIC program are included. (MP)

Describes how to implement numerical integration on a pocket calculator to solve two kinds of differential equations important in physics. The two equations are those defining simple harmonic and quantum harmonic motion. The half-increment method is used for this purpose. (GA)

Recommendations concerning the use of calculators in school are given along with the identification of important calculator features and functions with regard to present and expected curricular needs. (MN)

Describes the necessary procedures and equipment needed to modify the American Association of Physics Teachers' (AAPT) pocket calculator timer so that it can be controlled photoelectrically. (SL)

A straight forward process for working in fractions on any calculator is presented. The method involves converting a decimal back into a fraction in its lowest terms. (MN)

A case is made against the major argument which implies that the use of a calculator for arithmetic problems that can be done by hand will prevent a student from being able to do arithmetic when the calculator is absent. (MN)

A method for finding the area of a circle is described which involves finding points on the circle with the aid of a calculator and then applying the formula for the area of a polygon. (MN)

Presents compact algorithms, suitable for use with hand held calculators, for the calculation of potentiometric titration curves. (SL)

Presents an exact equation for calculating the volume of titrant as a function of the hydrogen ion concentration suitable for calculation on a hand held calculator. (SL)

Compares operating characteristics and features of programmable hand held calculators. (SL)

Discusses uses of programmable pocket electronic calculators in the secondary level classroom. Uses discussed include: grading, laboratory, exercises, computing T-scores, and a quantitative approach to chemical equilibrium. (SL)

An investigation of the cost of homeownership by constructing a mathematical model with refinements illustrates an important type of problem solving with calculators. (MNS)

Provided are four worksheets that are designed to capitalize on the use of calculators as teachers' partners in helping students to develop an intuitive feeling for percentage. Students also learn how to use the calculator's percent key to compute percentages. (MNS)

Activities concern exploring data and using the stem-and-leaf plot for displaying data. The three worksheets present activities, with brief directions for the teacher included. (MNS)
