THIS PORTFOLIO CONTAINS A NUMBER OF ILLUSTRATED PLATES, EACH ONE HIGHLIGHTING A SPECIFIC INSTRUCTIONAL MATERIAL. AMONG THE MATERIALS COVERED ARE CHALKBOARDS, BULLETIN BOARDS, GRAPHS, MODELS, AND CHARTS. IT IS FELT THAT THESE DEVICES ENCOURAGE CREATIVE THINKING IN THE CLASSROOM. A COMPANION BIBLIOGRAPHY CALLS ATTENTION TO RELATED MATERIALS. IT IS…

The major changes taking place in the occupational and industrial structure of the labor force are highlighted by graphic illustrations of changing manpower needs. Some apparent trends are: (1) the very rapid rate of growth of the total labor force, (2) the relatively slow growth rate of the manufacturing labor force, (3) the rapid growth of the…

This bibliography presents a series of studies that focus on the topic of networks and on the manner in which they have been considered in the literature. Each section of the bibliography provides a working set of references for one of the five major areas of research in which network analysis has been used. The first section deals primarily with…

Building Research studies show that overheating because of excessive solar heat gains can be troublesome in buildings of lightweight construction with large areas of glazing. The work being done at the Building Research Station provides the data for calculation of peak temperatures resulting from solar heat gain. Attention is given to window size…

The concept of structure has become a central concern in the study of human perception, learning, memory, and recall. The purpose of this paper is to present a method for analyzing structure--the theory of directed graphs--and to review research on teaching that has employed this method to investigate input structure, memory structure, or both. To…

Functions with a variety of properties (sets of discontinuities, unbounded derivations, etc.) are discussed. (SD)

The graph of this function is analyzed by using calculus methods and the computer. The graph in most texts is shown to be misleading. (MP)

Some applications of mathematics to bicycle gearing, speedometers, and bicycle braking are discussed. A method of calculating bicycle speed is developed. (MP)

A computer program is presented that generates problem sets involving sketching graphs of trigonometric functions using graphical addition. The students use calculators to sketch the graphs and a computer solution is used to check it. (MP)

The generation by computers of random numbers is discussed. A BASIC program is given that will generate a set of normally-distributed random numbers. (MP)

Nine examples of this principle show what a powerful tool it is. Several map coloring theorems are proven and some exercises are listed. (MP)

Recent mathematical descriptions of Bradford's distribution, and a new formulation that provides a more accurate estimation of the total number of papers and sources on a given scientific subject are presented. (Author/MBR)

A nontraditional approach of graphing equations using parallel axes produces some dual concepts when compared to graphing equations with the traditional perpendicular axes. (JT)

A graphing activity which allows students to work independently of the teacher and the textbook is described. The activity involves providing data in order to develop the skills necessary for interpreting the collected information. (JT)

Presents a theoretical model of collective bargaining based on the premise that the expectations and learning ability of the negotiators play a central role in bargaining. Discusses some implications of the model. Available from: Sage Publications, Inc., 275 South Beverly Drive, Beverly Hills, California 90212. (JG)
