Three constructions using thread are given for the hyperbolic paraboloid in addition to a method for constructing an approximation for the third-order saddle surface. (MN)

A conceptually elementary and geometrically based algorithm is presented to indicate how trigonometric functions can be calculated without using calculus. (MN)

An individualized learning system for college algebra was devised and tested. Results indicated that the individualized system was at least as effective as traditional approaches, and superior with respect to student attitudes toward the course. (SD)

An example is given to show the basic ideas of model theory; then a course is described in which the model theory approach is used. (DT)

An examination of a student question concerning a calculus problem leads to a discussion of some of the symmetric properties of a specific set of polynomials. (MP)

A description is given of a calculator-oriented arithmetic course given at a community college. Problem solving was the primary objective of the course. (MK)

Members of the New York State Mathematics Association of Two-Year Colleges were surveyed concerning characteristics of remedial programs, objectives of such programs, and facilities necessary. The results of the survey are reported and discussed. (SD)

A grouping procedure which systematically combines objects to satisfy a criterion specified by the investigator and groups those objects that are most alike first is discussed. Two such methods that can be easily demonstrated in the classroom setting with the aid of electronic calculators are presented. (MN)

A few suggestions are made concerning method and approach in teaching basic statistical thinking as part of a first course in statistics. (MN)

An approach to the teaching and selection of material in a technical mathematics course is given along with a list of topics basic to various technical programs. (MN)

Two techniques are given for helping students improve the quality of their class notes. (DT)

The use of DeMoivre's Theorem, the Binomial Theorem, and Pascal's Traingle in finding cos nx and sin nx is explained. (DT)

Described is a basic statistics course developed around statistical surveys which students conduct and analyze. An outline covering suggested classroom procedures and an outline giving directions for the statistics project are included. (DT)

Described is an autotutorial instructional program in basic college algebra for students with a minimal mathematics background. The course curriculum is divided into 32 units with the instruction recorded on audio-tapes. Students move at their own pace and receive individual help from the instructor. (JP)

A review and a course outline of a workshop conducted at Wayne General and Technical College, a branch of the University of Akron, during seven weeks of Spring Semester 1980 are presented. (MP)
