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 presents a method of producing a scatter diagram of data on two variables with Pearson product moment correlation of .50; he also provides a proof that the method will work for any number of data pairs. (SD)

A discussion of autosegmental phonology (AP), a theory of phonological representation that uses graphs rather than strings as the central data structure, considers its principal constraint, the "No Crossing Constraint" (NCC). The NCC is the statement that in a well-formed autosegmental diagram, lines of association may not cross. After…

The past decade has seen a substantial growth in methods and schemes for the display of multivariate data. This paper encompasses a sketch of the history of multivariate displays, from the pre-Columbian Quipu to Chernoff's Face; examines a number of techniques; describes their construction; illustrates their use; and comments on their efficacy.…

Although computer graphics professionals usually consider only technical graphic design issues, recent improvements may make the only limiting design factors the user's purpose, imagination, style, and taste rather than computer hardware or software technology. Computer graphics designers can be helped to avoid pitfalls by understanding the visual…

Several activities are described which give children experience with body measuring and estimating. Ratio and proportion and graphing are also involved. Samples of individual worksheets are provided as is a poster. (LS)

This mathematical model is intended to be a tool for the monitoring of the bargaining process and to provide the ability to predict the form of bargaining outcomes given certain initial conditions. It applies to situations in organizations in which the conflict between the expressed desires of interest groups are settled by a bargaining process…

This study examined cooperative planning for change between educational linkers and 11 schools. Qualitative field research methods were used to determine the effects that school context factors, the school-agency relationship, and linking agent behavior had on project outcomes. Results showed that the school context and the school-agency…

THE PROBLEM WAS TO DETERMINE WHICH COMBINATIONS OF VERBAL AND GRAPHIC MATERIALS LEAD TO THE MOST EFFICIENT LEARNING. NINETY-ONE UNIVERSITY COLLEGE STUDENTS WERE DIVIDED INTO EIGHT GROUPS WHICH READ THE SAME INSTRUCTIONAL MATERIAL (ON ELECTRICAL CIRCUITRY) IN VERBAL, GRAPHIC, VERBAL-GRAPHIC, OR GRAPHIC-VERBAL FORM. HALF OF THE SUBJECTS WERE…

This is part one of a three-part SMSG calculus text for high school students. The aim of the text is to develop some of the concepts and techniques which will enable the student to obtain important information about graphs of elementary functions. Chapter topics include: (1) polynomial functions; (2) the derivative of a polynomial function; and…

This is part three of a three-part SMSG calculus text for high school students. The aim of the text is to develop some of the concepts and techniques which will enable the student to obtain important information about graphs of elementary functions. Chapter topics include area and the integral, differentiation theory and technique, mathematical…

This paper compares population growth and affluence in developed nations in which per capita income and consumption have been relatively high, and in developing nations in which per capita income and consumption have been relatively low. The paper is one in a series of occasional publications intended to increase understanding of the…

To determine the effect of format on the communication of information and the range of qualitative reaction, data was presented by bar graphs, data tables and natural language text to 24 staff members of the Southwest Regional Laboratory. No difference in acquisition of information among the staff members was shown. Subjects preferred data tables,…
