Presents a problem which requires students to become familiar with the computation and interpretation of a non-parametric statistic for rank correlation. Purpose of problem is to help students to see meaningful application and to present a problem that does not have a text-book answer. (BR)

Describes a method of calculating the equilibrium constant from free energy data. Values of the equilibrium constants of six Bronsted-Lowry reactions calculated by the author's method and by a conventional textbook method are compared. (LC)

Presents a problem in standing waves that provides an example of the mathematics used by theoretical physicists to generate predictions of new phenomena from fundamental background knowledge. Mathematical analysis required to solve problem is accomplished by simple graphical processes. (BR)

Presents a technique for teaching the lower ninety percent in mathematics. Concentrates on converting English statements, both expressed and implied, into one or many mathematical statements. Emphasis on translating in a direct, piecemeal, pure, and complete manner (DPPC). This method differs from others in that it is concrete rather than…

Presents procedures, results, and conclusions of a research study designed to determine whether providing knowledge of results after each response on an arithmetic exercise would result in performance different from that obtained when knowledge of results is provided following completion of the exercise. The subjects were three fourth grade…

The reason for the inability of students to master the solving of word problems in algebra is identified as the failure to organize and analyse the problems. The author's approach to the solution of these problems, involving writing symbols for the unknown(s), generating equations, solving the unknown(s) and interpretation is presented through…
