Two graphing activities are supplied for providing practice in plotting points in the rectangular coordinate system. (JT)

Four activities providing experience in building bar graphs, reading and building circle graphs, and graphing in a coordinate plane are described. (JT)

A system similar to the slope method of graphing a linear equation is described for graphing parabolas. (JT)

This article provides a discussion of issues related to the standardization of technical illustrations using graph paper based on multiples of 100 mm. (SD)

In the process of fitting a quantitative synthesis model, the assumption of homogeneous effect size variation is assessed via omnibus test statistics. Graphical representations of data on techniques for teaching composition skills are used to help determine the extent to which sample estimates deviate from modeled population estimates. (TJH)

Fourth graders (n=204) and seventh graders (n=185) were given a prior-knowledge inventory, a graph test, and reading and achievement tests during four testing sessions. Significant predictors for graph comprehension were identified for both grade four and grade seven students. The results suggest that children should be involved in graphing…

Describes how to involve students in higher level thinking processes through the use of microcomputer graphing software. Provides two complete lesson plans for upper elementary or middle school students, one on geography/state products study and the other on civil war resources. (JDH)

The author suggests that slope be introduced as a topic independent of graphs, and that it be presented in a way that makes some sense of using a fraction to represent it. Many examples are included. (MNS)

Provides examples in which graphs are used in the statements of problems or in their solutions as a means of testing understanding of mathematical concepts. Examples (appropriate for a beginning course in calculus and analytic geometry) include slopes of lines and curves, quadratic formula, properties of the definite integral, and others. (JN)

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

Describes origin, development, and current state of Research Libraries Information Network's (RLIN) Command Analysis System, which digests large quantities of raw data on RLIN use and performance and produces useful graphs and reports. Recent results of system and pragmatic issues in analysis of online systems are noted. (7 references) (EJS)

Discusses the hardware and software necessary to generate charts and graphs to illustrate numeric data using a microcomputer. The manufacturer, price, operating system, memory requirements, and types of graphs they can produce are given for nine graphics software packages and seven inexpensive plotters. (MBR)

Examines the line graphing ability of middle/high school students (N=625) to provide baseline data on the mastery of line graphing subskills. Results show that seventh- and eighth-grade students were less successful in graphing than high school students, suggesting that graphing skills should be introduced and emphasized in earlier grades. (JN)

A method for assessing scientific performance based on relationships displayed numerically in published documents is proposed and illustrated using published documents in pediatric oncology for the period 1979-1982. Contributions of a major clinical investigations group, the Childrens Cancer Study Group, are analyzed. Twenty-nine references are…

A supplementary treatment is proposed which helps identify sources of bias affecting groups of test items. This treatment is illustrated with the tranformed item-difficulty method as applied to an evaluation of a test used to help select applicants to be admitted to an aviation training program.
