Reviews pattern recognition techniques of multivariate statistical analysis as a means of data reduction. (SL)

A series of interesting mathematical applications for the greatest integer function are presented. (JT)

Three activities involving children with the probability concepts of random selections and sample size are provided. (JT)

The process of design and construction of a mathematics program based on the interests of children is presented in an address read at the Sixth Biennial Conference of the Australian Association of Mathematics Teachers. (MT)

Formulae are proposed for the distinct cases of monatomic and diatomic gas volumes. Eight figures illustrate the article. (Author/MA)

This article provides a manipulative demonstration of the relationship between the squares on the sides of a right triangle. Materials are listed and directions are given for the student. Illustrations are included. (Author/MA)

Reviews the application of population balance mathematical treatment to transfer operations in chemical engineering. (SL)

Solves the quantum mechanical problem of the bound states corresponding to a sum of several delta-shell potentials. (SL)

A teacher-made mathematics kit with activity cards, worksheets, and record-keeping grids is described. A procedure for working with the students and the kit for reinforcing computational skills is outlined. (JT)

The theory of biorhythms is explained after which a sample program written in Fortran that will plot a person's biorhythms and a sample run are given. (MN)

An elective course aimed at giving tenth-grade students some experience with practical arithmetic problems is outlined. The two-week course is designed primarily for students who will be leaving at the end of the year and includes topics such as calculators; earning, spending, and saving money; tax; and buying a car. (MN)

A course is described which gives students experience in creating practical mathematical models of "real" problems, relating the mathematical solutions of the model to the original problem, and recognizing non-mathematical constraints on possible solution approaches. The students assume the role of industrial mathematicians while their tutors play…

Through the use of sequences, geometric progressions and permutations, the author investigates some interesting and unusual questions concerning the number of moves required by each disc in solving the Tower of Hanoi puzzle. (JT)

The author argues that the idea of successive approximations is one of the most important in applied mathematics. The role of approximation in the development of the calendar is described. (SD)

The author addresses the structuring of a science and mathematics curriculum by creating a model for the learning experience. The model is based on learning hierarchies. (SD)
