This study tested the effectiveness of teaching concepts in high school economics first by verbal instruction and then by graphs or other imagery. Eighty-three high school seniors were taught by the method above, by reversing the order of that method, and by verbal instruction only. Results are discussed. (Author/MT)

Discusses the use of quantitative graphs in newspapers and identifies 10 common problems to avoid in the use of informational graphics, including (1) the tilted graph; (2) the stacked graph; (3) the convention-violating graph; (4) the unnecessarily three-dimensional graph; and (5) the overly complex graph.

An interesting graphical interpretation of complex roots is presented, since it is probably unfamiliar to many mathematics teachers. (MNS)

Four empirical laws of bibliometrics--anomalous number, Lotka's, Zipf's, and Bradford's--together with Laplace's "law of succession" and de Solla Price's cumulative advantage distribution are shown to be almost identical. A simple model shows that the frequency forms conform with inverse square law over appropriate interval. (Fifteen…

Describes a kinship graph system implemented in the APL computer language, including the way in which information about individuals is entered into the database and the various ways in which the computer can trace and display family relationships. (MBR)

This guide provides students with practice for all the major types of graphs they are likely to encounter. It includes information on graphs of various families of algebraic functions; bar, line, and circle graphs; the creation, reading, and interpretation of graphs; and the use of graphing calculators.

This report is a compilation of input and output measures and other statistics in reference to Idaho's public libraries, covering the period from October 1997 through September 1998. The introductory sections include notes on the statistics, definitions of performance measures, Idaho public library rankings for fiscal year 1996, and a state map…

Three examples of the use of intuitive geometrical ideas in clarifying analytical results. (MM)

A recently developed readability formula which requires little time and few mathematical computations is explained. (Editor)

The author demonstrates the simplicity in using the Readability graph, and illustrates her comments with specific examples. (Editor)

The design and study of library information networks are enhanced by the use of the concepts which have been developed by graph theorists. This paper proposes a general network structure which is a good model for a wide variety of library and other information networks. (4 references) (Author/NH)
