Knowledge representations and mental models from graphically presented information were investigated for 98 college students with different levels of mathematics experience. The subjects were drawn from a remedial algebra course (n=35), a second semester calculus course (n=35), and a calculus-based statistics course (n=28); they were all exposed…

Designed to help institutional researchers transform data into useful information, this paper discusses principles for presenting research results to administrators in the top levels of management. The first section describes ten fundamental principles of data presentation: knowing what information is needed; knowing when the information is…

Ten issues of a monthly social studies resource, each with a different topical focus, are included in this document. The issues focus on: the American family; the environment; the developing world; U.S. and world population; U.S. and world energy; the arms race; employment and housing; world product and trade; social programs in the federal…

The Exstatix statistical analysis software package by K. C. Killion for use with Macintosh computers is evaluated. In evaluating the package, the framework developed by C. J. Ansorge et al. (1986) was used. This framework encompasses features such as transportability of files, compatibility of files with other Macintosh software, and ability to…

The use of quantitative graphics in newspapers requires achieving a balance between being accurate and getting the attention of the reader. The statistical representations in newspapers are drawn by graphic designers whose key technique is fusion--the striking combination of two visual images. This technique often results in visual puns,…

This research illustrates how statistical analysis of data was presented by the plaintiff's attorneys as evidence in litigation involving sexual and racial discrimination in the case Green v. City of Gadsden. Bar graphs depict the sexual and racial compositions of (1) members of the Gadsden Police Department (GPD), (2) members of the GPD in…

In the Connecticut School Effectiveness Project, data are collected on seven characteristics of effective schooling: safe and orderly environment, clear school mission, instructional leadership, high expectations, opportunity to learn and time on task, frequent monitoring of student progress, and home-school relations. These data are collected…

A subset of Statistical Process Control (SPC) methodology known as Control Charting is introduced. SPC methodology is a collection of graphical and inferential statistics techniques used to study the progress of phenomena over time. The types of control charts covered are the null X (mean), R (Range), X (individual observations), MR (moving…

The research on which this study is based found that 50% of the errors in English of French-speaking students were due to interlingual causes and 50% had their source within the target language itself. The question of a correlation between the errors and the teaching method used is explored. Five methods are discussed and evaluated:…

A photocopier or scanner can be used to produce not only the standard motion graphs of physics, but a variety of other graphs that resemble gravitational and electrical fields. This article presents a starting point for exploring scanner graphics, which brings together investigation in art and design, physics, mathematics, and information…

This publication is a statistical report that presents a variety of school district cost data for the purpose of giving the California Legislature information to use in adjusting the state foundation program for public school support. Following a brief section that summarizes the major trends identified in the study, separate sections focus in…

This paper contains sample exercises that investigate weather and air quality relationships for use in college-level introductory courses in climatology and meteorology. The exercises will provide students with an opportunity to apply meteorological principles to a specific geographic location, in an effort to better understand the significant…

Three lengthy tables and four charts present information on the 1981-82 planned tax effort of each of Pennsylvania's 501 school districts and 67 counties. The tax effort, or "equalized mills," equals each district's budgeted taxes divided by its projected 1981 market value. The report gives a brief illustration of how the tax effort…

This study guide is part of an interdisciplinary course entitled the Science and Engineering Technician (SET) Curriculum. The course integrates elements from the disciplines of chemistry, physics, mathematics, mechanical technology, and electronic technology, with the objective of training technicians in the use of electronic instruments and their…

This description of the PLATO system over its first seven years describes the development of PLATO III and PLATO IV, lists financial supporters of the PLATO project from 1960 to 1977, outlines highlights in its history, and provides a chronological list of publications about the system. Figures include the locations and increasing numbers of PLATO…
