This is a preliminary report on research into computational errors made by six- and seven-year-olds. (Author/MK)

Discussed is the classical partition function for the ideal gas and how it differs from the exact value for bosons or fermions in the classical regime. The differences in the two values are negligible hence the classical treatment leads in the end to correct answers for all observables. (Author/DS)

A teacher describes the experiences of her fourth-grade students when using calculators during mathematics class. (MK)

This annotated bibliography includes activities with calculators in the areas of computational skills, geometry, measurement, number pattern recognition, and probability. (MK)

Ways of using calculators to presents the concept and methodology of concurrent processing are discussed. Several problems that could be used to compare sequential versus concurrent processing are presented. (MK)

The computational difficulty of the word problem sections of eight standardized achievement tests was analyzed with respect to the variety of computational procedures and the number of digits per whole number computation. Analysis reveals considerable variation among the current tests in terms of computational procedure and difficulty. (Author/MK)

Calculator-based activities are presented that may be used as the framework for a unit to replace much of the usual algebra material on exponential functions and logarithms. (MP)

The internal operations of this computer symbolic mathematics system are described in detail in order to explain the accomplishments of the computer. (MP)

The results of this study show no evidence of a decline in mathematics learning in elementary school classes that used calculators and suggested that primary students may benefit from using calculators. (MP)

An appeal is made for a more formal treatment of the topics of estimation and reasonableness of answers in the school mathematics curriculum. (MP)

The calculator is used to help students discover the Rule of 72 which is, in turn, used to investigate problems involving population, inflation, and energy reserves. (MP)

Two studies sought to determine the developmental relationship between the child's use of counting as a notational symbol system to extract, compare, and reproduce numerical information and the development of number conservation. Subjects were four- to six-year-old children in Study 1 and seven- to nine-year-old learning disabled children in Study…

Presented is a derivation for the matrix representation of an arbitrary boost, a Lorentz transformation without rotation, suitable for undergraduate students with modest backgrounds in mathematics and relativity. The derivation uses standard vector and matrix techniques along with the well-known form for a special Lorentz transformation. (BT)

An explanation of strong base effect demonstrates that deprotonation of a reactant shifts an equilibrium toward reactants in the same way that a deprotonation of a product shifts it towards products. (Author/SA)

Compares the relative difficulty of four types of word problems. Other variables considered are grade level, sex, order of testing, and performance on a computational skills test. (MK)
