Three calculation methods were compared in solving problems involving frequency distributions, manual, basic calculator, and advanced calculator. Calculators were more efficient but there was no difference in calculator type. (MP)

Statistical problems were used to test the hypothesis that calculators facilitate problem solution by saving time and increasing accuracy. Manual, basic machine and advance machine methods were used. (MP)

Investigated were the effects on computation performance of amount of prepractice and type of calculator, when students were told to work very fast vs very accurately. (MP)

Three calculation methods--handwork, or simple or advanced calculators--and two levels of difficulty--easy or hard--were used to investigate the effects on computational performance. (MP)

Solving statistical problems using a calculator with sophisticated features was compared to solving the same problems by hand. The calculator group was more accurate and took far less time. (MP)

The study reported is the first in a series of investigations designed to empirically test the hypothesis that calculators reduce quantitative working time and increase computational accuracy, and to examine the relative magnitude of benefit that accompanies utilizing calculators compared to manual work.

The first part in the serialized version of a book on the use of calculators for problem solving is presented. It contains prefaces for teachers and students and a chapter on getting started which includes topics such as symmetries, operations, powers, and chaining. (MP)

Chapter two of the book, "Problem Solving with Calculators,"is presented. Topics covered include parts of a problem, steps in problem solving, guessing, and methods of calculation. (MP)
