As the seventh lesson of the Articulated Multimedia Physics Course, instructional materials are presented in this study guide with relation to the force combination. The topics are concerned with the definition and units of forces, sliding forces on inclined planes, and the equilibrant of two or more forces. The content is arranged in scrambled…

A survey test in mathematics (see TM 000 965) was administered to all pupils in Grade 7 of the Vancouver School System. Test content included arithmetic fundamentals, modern mathematical concepts and mathematical applications in problem solving. A summary of test results is presented in three tables. (CK)

This test was designed to cover the new seventh grade mathematics course (see TM 000 964) in the Vancouver schools. The 45-item multiple choice test designed to be completed within a 70 minute period stresses arithmetic fundamentals, modern mathematical concepts, and mathematical applications in problem solving. (CK)

We concern ourselves with the hypothesis that two variables have a perfect disattenuated correlation, hence measure the same trait except for errors of measurement. This hypothesis is equivalent to saying, within the adopted model, that true scores of two psychological tests satisfy a linear relation. Statistical tests of this hypothesis are…

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…

Language arts games are described that combine mathematical experiences and language development.

Using a pegboard and different colored pegs, students were able to visualize mathematical concepts, generate and solve problems, and test hypotheses. Illustrations included. (MA)

A mathematical model is developed for making population projections at five-year intervals from 1975 to 2000. The model starts with 1970 population figures, broken down by age and sex, and incorporates the change factors of birth, death, immigration, and emigration. A computer program is included along with projection outputs. (MN)

Transformations are defined and described through many examples. Teaching aids and activities for teaching about transformations are suggested. (JT)

Indicates that only 21% of respondents (secondary school math teachers) used computer-assisted instruction for tutorial work, physical models to interpret abstract concepts, or real-life application of the arithmetic or algebraic manipulation. Recommends that creative teaching methods be applied to problem solving. (NKA)

This article illustrates how questions from elementary finance can serve as motivation for studying high order powers, roots, and exponential functions using Logo procedures. A second discussion addresses a relatively unknown algorithm for the trigonometric exponential and hyperbolic functions. (PK)

Presents ideas that are intended to convey new insights on familiar topics and to enhance pedagogy. The mathematical topics addressed are applications of transformations to numerical integration, the golden ratio, Cramer's rule, a counting problem, and the general form of the arithmetic-geometric mean inequality. (PK)

Describes an exhibition of "mathematically rich" cloths. The themes chosen to be included were symmetry, number, creativity, information handling, and problem solving. The project was an outgrowth of work to take ordinary daily situations and analyze them mathematically. (PK)

Presents results of an investigation of a formula for rank correlation. The exploration turned up an unexpected connection and showed the formula to be far from arbitrary. (PK)

Includes materials in reproducible format designed to help students read and draw distance-time graphs and use the slopes of these graphs to draw conclusions about car speed. (PK)
