The author shows how changing the restriction context of "Fermat's Last Theorem" alters the statement of impossibility. (MN)

The author uses mathematical models that involve only algebra and a few basic ideas in discrete probability to describe the frequency of conception in large human societies. A number of calculations which can be done by students as exercises are given. (MN)

The author presents a method of teaching the concept of limit. (SD)

The need for realistic applications to be included in mathematics courses is stressed. Several general examples of realistic problems are suggested. (DT)

A programming problem on calculating the roots of a quadratic equation is used to illustrate the inexactness of computation with a digital computer. (DT)

The performance of community college students given instructional objectives was compared to performance of those not receiving objectives. A total of four instructional units were presented. On one of the units and on the students' combined scores for all four units, results showed significant differences favoring students receiving objectives.…

Pure and applied mathematical research is discussed briefly. The author gives an example of mathematical research on functional differential equations that was motivated by a student error on a calculus examination. (MK)

Diagnostic and instructional support systems for introductory statistics were developed to meet the need for good tests and resource materials. (MP)

Students in an elementary algebra course use audio-cassette recordings of lecture materials to accompany their textbooks. (SD)

By converting functional equations to cylindrical coordinates, plotting points on cardboard, and connecting these points with thread, one can make three-dimensional string figures illustrating the behavior of functions for which the derivative is not always defined. (SD)

The author conducted a survey of the departments requiring a finite mathematics of students in order to determine the usefulness of topics included. Findings showed that the topics covered were generally considered important, with elementary matrix algebra the least popular. (SD)

The students in a basic course on probability and statistics in Trinidad demonstrated that the number of fatal highway accidents appeared to follow a Poisson distribution while the length of time between deaths followed exponential distribution. (MN)

Sums for divergent series that were seriously considered by eighteenth century mathematicians are shown to have reappeared as result of new interpretations for divergent series that make these previous conclusions valid. (MN)

Broad objectives and a Five-Year Plan are given for the Developmental Mathematics Curriculum Committee of the American Mathematical Association of Two Year Colleges. (MN)

A method for converting a three-dimensional coordinate system to a two-dimensional coordinate system is explained. (MN)
