Several examples are given of a variety of nonstandard problems, not ordinarily found in texts or courses, now accessible to students who have programmable calculators. These include: (1) finding limits; (2) evaluating infinite series; (3) calculating finite series; (4) computing variable length products; (5) solving equations; (6) searching for…

In response to an increasing demand for faculty evaluation, focus is on elements of a successful evaluation program. It is suggested that faculty must be consulted in order to arrive at a mutually agreed upon structure, incorporating such areas as which sources should provide the information or data on which the evaluation will be based. Another…

This study was an attempt to provide some evidence on the effects of calculator usage with primary-age children. Specifically, the study compared the performance of children who had access to calculators for an extended period of time, and whose teachers used calculators in specified instructional ways, with children who did not have access to…

Five reports from a 2-year study are presented. Frequencies and descriptions of systematic errors in the four algorithms in arithmetic were studied in upper-middle income, regular, and special education classrooms involving 744 children. Children were screened for adequate knowledge of basic facts and for receiving prior instruction on the…

The purpose of this investigation was to determine the relationship between the acquisition of conservation skills and achievement in mathematics. The conservation skills measured were numbered, mass, area and volume. Mathematics achievement was measured by the Computation, Concepts, Problem-Solving and Total Mathematics scores on the Metropolitan…

Compared the computational performance of two groups of arithmetic teachers: one group tested in 1930 and the other in 1973. Results indicated that the 1973 teachers performed significantly better than the 1930 teachers. (JMB)

Presents the use of quantity calculus in calculations arising in volumetric analysis and in the more general field of chemical stoichiometrics. (HM)

Described are two methods of calculating developed by the Dutch WISKOBAS Project: addition and subtraction with a loop abacus and multiplication using a grid model. (MP)

The objective were to explore some of the ways in which the calculator can be used and to determine the effects. Areas covered are: computation, mathematics readiness, problem solving, and discovery learning. (MP)

This bibliography lists books containing classroom-ready materials that can be used in conjunction with routine mathematics lessons. A description is given of six of these books. (MP)

Results are given of a 14-question survey of students related to the use of calculators in school. The use of mathematical tables as opposed to calculators is discussed. (MP)

The new, and prevalent, raised-dash notation (for subtraction) appearing in school mathematics texts is examined, especially for its effects on students' computational skills. Reasons for a return to the standard notation of the centered dash are presented. (Author/MN)

Describes the use of programmable calculators to perform classroom controlled experiments on economic models. The complete program for exploring the dynamics of the Harrod-Domar equation is given. Some difficulties encountered and statistical uses are mentioned. (BC)

The use of calculators in mathematics classes of eight-year-olds was investigated. Results showed that the experimental classes were quicker and more accurate in addition, subtraction, and multiplication than the control classes at the end of the year. (MN)

A method for approximating the nth root of any positive number that requires only a four-function calculator with a square-root key and repeat multiplication capability is given. (MN)
