This book contains 40 lessons in problem solving divided into five chapters. Chapter 1 contains several lessons in which solutions are derived through investigation of numerical patterns. Chapter 2 contains lessons in which problem-solving situations are presented in a graphical context. It also includes two lessons in which students construct…

Information graphics or diagrams are two-dimensional maps of relationships that present information. Creators and interpreters of diagrams need to know what makes some diagrams more effective in communicating information. This paper suggests a theoretical framework for diagram classification to make this possible. This framework consists of two…

The statistical analysis of data from a single-subject design is somewhat controversial. The procedure most often chosen to examine data from a single-subject design involves the visual inspection of the graphed outcome variable over time. Problems associated with this procedure are discussed, and questions about the use of traditional statistical…

Outlines a teaching method using graphs for explaining phase changes and the effect of pressure and the relationships between temperature, entropy, enthalpy, energy, Gibbs function, Helmholtz function and volume. (GS)

Library directors at 164 universities, colleges, and community colleges in California were surveyed in fall 1986 on their hiring of temporary librarians over 5 fiscal years, 1982-83 through 1986-87. The response rate was 90%. Results indicated that: (1) all types of academic libraries employ temporary librarians; (2) the number of temporary…

The use of computer graphic techniques with basic student enrollment statistics is examined to promote understanding of changes in student flow as a function of spatial distribution. Basic initial student enrollment data that serve as input into predictive flow models were modeled at Eastern Kentucky University. The following commercially…

A graphical method is proposed which allows one to visualize a real matrix and its inverse. In this scheme, various special properties of the matrix are easily recognized. Up to 5x5 matrices can be graphed on an average page if the range of values does not exceed two orders of magnitude. (Author/LS)

Two new types of graph paper are described; focus-focus conic paper and focus-directrix paper. Both types make it easier to draw families of conics. Suggestions for further work are given as is a method for establishing a connection with other ways of looking at the conic sections. (LS)

Reviews the equations of motion and the use of a sine-sine coordinate grid for convenient plotting or analyzing of Lissajous figures. (Author/GS)

A REVISION OF THE READABILITY GRAPH WITH DIRECTIONS FOR ITS USE AND VALIDTIY DATA ARE PRESENTED. THE USE OF THE GRAPH INVOLVES WORD SAMPLES, NUMBER OF SENTENCES, AND NUMBER OF SYLLABLES. THE LATTER TWO ARE PLOTTED ON A GRAPH TO ASCERTAIN GRADE LEVELS. THE CORRELATIONS OF THE READABILITY GRAPH WITH THE DALE-CHALL, FLESCH, AND SPACHE FORMULAS ARE…

The goal of this pamphlet is to provide instructors of various scientific disciplines with mathematically accurate graphs of elementary polynomial functions. The figures in this pamphlet are intended to provide suitable material for the preparation of classroom handouts and overhead transparencies. In addition, sample sets of exercises are…

Graphic statistics as developed by John Tukey have some practical benefits for precision journalists as they assist in spotting trends not as easily noted without the use of nonparametric statistics. Some especially helpful graphic statistics are: "stem-and-leaf display,""box plots,""froots," and "flogs."…

INFORMATION ABOUT THE STATUS OF WORKING WOMEN AND THEIR UNDERUTILIZATION IN THE NATIONAL WORK FORCE IS PRESENTED IN SUMMARY AND GRAPH FORM. ALTHOUGH PROGRESS HAS BEEN MADE IN ASSURING WOMEN EQUALITY OF PAY AND NONDISCRIMINATION IN EMPLOYMENT, MUCH NEEDS TO BE DONE TO IMPROVE THE UTILIZATION OF THEIR ABILITIES. MOST WOMEN WORK TO SUPPORT THEMSELVES…
