The article describes the Mental Mathematics System, a number of formulas designed to develop mathematical skills in elementary and junior high school gifted and talented students. Formulas are provided for multiplication. The formulas for mental mathematics are noted to promote student interest in the subject. (SBH)

Presents a discussion of the rethinking of the role of literacy in African nations. Emphasis is needed on measurement concepts for peasants. Cultural motivations are suggested as important considerations when planning literacy programs. (SA)

This paper elaborates on the work of Cardinet, and others, by clarifying some points regarding calculations, specifically with reference to existing computer programs, and by presenting illustrative examples of the calculation and interpretation of several generalizability coefficients from a complex six-facet (factor) design. (Author/RL)

Classroom games designed to develop mathematics skills in elementary school children are presented. These games involve personalizing metric measurement, telling time by television, creating an all-math newsletter, addition puzzles, subtraction games, division cards, multiplication, fractions, and measurement. (JD)

It is suggested that the reasons for teaching the standard written algorithms for calculations are not out of date. Alternative algorithms, such as mental algorithms, calculators, and nonstandard written methods, are discussed. (MP)

Described is a method for the illustration of the statistical nature of measurements in quantum physics by means of simulation with pocket calculators. The application to examples like the double-slit experiment, Mott scattering, and the demonstration of the uncertainty relation is discussed. (Author/HM)

Describes a general purpose algorithm which enables one to calculate the allowed energy eigenvalues for an arbitrary potential. Results of a calculation where a centrifugal potential is added to the hydrogenic Coulomb potential are discussed. (Author/HM)

The theoretical basis for the calculation of hydration numbers is developed. (BB)

Two problems are presented and discussed as a means of demonstrating that the calculator can play a more important role in the mathematics class than simply as a computational tool. (MP)

A number of mathematical games, tricks and puzzles, are described as a way to make drills for elementary school students as interesting as possible. (MP)

These worksheets will provide students with experiences in identifying largest and smallest single-digit numbers, in writing names for single-digit numbers, in tests of divisibility, and in writing number sentences. (MP)

Describes six crystallographic programs which have been developed to illustrate the range of usefulness of programmable calculators in providing computational assistance in chemical analysis. These programs are suitable for the analysis of x-ray diffraction data in the laboratory by students. (HM)

Described is the use of an interactive terminal-oriented computing system that has access to files of thermodynamics data. (Author/SA)

Discussed is the virial theorem, which is useful in classical, quantum, and statistical mechanics. Two types of derivations of this theorem are presented and the relationship between the two is explored. (BT)

Three examples are given illustrating the use of the calculator in problems where determining patterns and making conjectures are stressed. (MP)
