The purpose of this study was to investigate the effects on achievement and attitude resulting from the use of a calculator-based curriculum and a classroom set of hand-held calculators in ninth-grade general mathematics. Six teachers participated in the study, each having one class in the calculator treatment and one class in the non-calculator…

The extent of the direct sources of economic stimulus by Georgia State University in Atlanta is estimated. The initial sources of positive economic impact are the local purchases by the university, the payroll spending of its faculty and staff, and spending by students drawn to the local area by the university. This study used techniques developed…

For STET students who still have difficulty with the basic operations on whole numbers, the author has developed a "periodic table" of whole numbers, which can be used to add, subtract, multiply, and divide. (MP)

Cost-per-student calculation methods produce different values that create problems for decision-makers in evaluating their use. Several available cost models are compared and differences in methods of looking at the costs of health sciences education are discussed. (LBH)

Capturing junior high school students' interest in computation is the aim. Three activities are described in which computation acts as a needed tool within a problem-solving context. (MN)

A mathematical game that reinforces basic multiplication facts, strengthens concepts of factors and multiples, and also provides arithmetic drill is described. Four variations of the game are also provided. (JT)

Four games and some variations which can be used to practice facts and operations are described. (JT)

Reptiles are used as a theme on four worksheets for practicing skills in computation, measurement, comparison, reading, and problem solving. (MNS)

The article recounts a conversation with preschool students about calculators. The author found the children to be familiar with calculators. Also, the Calculator and Mathematics Project, Los Angeles (CAMP-LA), a project which assumes every child has a calculator, is briefly described. (PK)

Describes the use of assumptions, restrictions, and constraints in solving difficult analytical problems in engineering. Uses the Navier-Stokes equations as examples to demonstrate use, derivations, advantages, and disadvantages of the technique. (RT)

Computing pi efficiently has been of great interest to mathematicians for centuries. This article presents an algorithm to solve this problem through skillful computer use. (PK)

Explains the use of the 3-dimensional analytic geometry method to find values for a field geology problem. Gives a description of the mathematical theory for this method which can be applied to data obtained by drilling as well as open surfaces, and a computer program. (RT)

The author suggests that, through using the outlined question model and suggested classroom activities, elementary students will improve their abilities to analyze routine, one-step word problems and make a plan for the solution. It is further argued that the same algorithm can be applied to multistep problems by using specified questions. (PK)

Describes a study designed to investigate the relationship between students' learning of the standard double-digit addition algorithm and basic fact mastery or numeration concepts. Results suggest basic fact mastery and knowledge of numeration concepts may not be as necessary as previously assumed to learning multidigit addition. (PK)

Presents a method of teaching two-column addition which the authors argue is based on Piaget's theory and fosters the children's own natural thinking. The method does not use objects such as straws bundled or base-ten blocks. (PK)
