In a high school writing workshop, students frequently would go through multiple essay drafts and conferences with the teacher and fellow students before realizing that their theses were incorrect. A teacher devised the "lexivision" to address this problem. Students used Venn diagrams, graphs, or flow charts to represent concepts in the…

This document presents 122 pages of illustrative maps, tables, and graphs that depict the following features of Europe: size, population, resources, commodities, trade, cities, energy, industries, demographic statistics, food and agriculture, aspects of the national governments, and aspects of the national economies. Numerous individual country…

This investigation of cognitive effort begins with a review of cognitive principles relating to memory and graphic encoding of information. The cognitive framework described allows explanation of improved memory due to reparsing of graphic representations. It also provides the basis for optimizing graphical material design to insure best retention…

A demonstration project was undertaken to determine whether 1978 telefacsimile technology could address the needs of rural public libraries in a cost-effective manner. The TALINET design utilized local public library staff and a research/resource information staff at the University of Denver to research questions and deliver information to five…

For decades, every chemical engineer has been asked to have a background in separations. The required separations course can, however, be uninspiring and superficial because understanding many separation processes involves conventional graphical methods and commercial process simulators. We utilize simple, user-­friendly mathematical software,…

This profile provides data from the 1980 census on American Indians, Eskimos, and Aleuts in the total U.S. population, on American Indian reservations, and in historic areas of Oklahoma (excluding urbanized areas). Bar graphs illustrate data on (1) the overall population; (2) population by geographic region; (3) population by standard federal…

The advent of calculators for graphing and function plotters is changing the way college algebra and calculus are taught. This paper illustrates how the machines are used for teaching the following: (1) domain and range; (2) product and quotient inequalities; and (3) the solving of equations. Instructional hints are provided for each topic with…

This book provides elementary and middle school teachers with practical ideas on the use and teaching of graphs. Five sections consist of: (1) "Graphs--What Are They and How Are They Used?"; (2) "Levels of Graph Comprehension"; (3) "Collecting, Organizing, and Analyzing Data"; (4) "Constructing, Interpreting, and Writing about Graphs"; and (5)…

The United Soviet Socialist Republic (USSR) is the largest country in area in the world and ranks third in world population. The geography and the people of the USSR are documented in a series of reproducible black and white maps and graphs designed for use as classroom instructional materials. Maps, graphs, charts, and tables with information…

The high percentage of high school pre-algebra students having difficulty learning the abstract concept of graphing ordered pairs on the Cartesian rectangular coordinate system was addressed by the creation and implementation of a computer-managed instructional program. Modules consisted of a pretest, instruction, two practice sessions, and a…

A graph is an example of a symbol system which encodes information through the juxtaposition of marks in a two dimensional plane; decoding the meaning of a graph uses specific attributes of the human visual system. This study was undertaken to identify some variables critical to graph interpretation as a first step in designing better curriculum…

Graphical methods for displaying data, as well as available computer software and hardware, are reviewed. The authors have emphasized the types of graphs which are most relevant to the needs of the National Center for Education Statistics (NCES) and its readers. The following types of graphs are described: tabulations, stem-and-leaf displays,…

Noting that technology in the field of graphics and printing has permitted greater use of color, photographs, and graphics by newspapers, a study examined the effects of economic factors such as newspaper competition and ownership on the actual use of new technology for color and graphics. The newspaper sample, stratified on the basis of ownership…

Two studies were conducted of students in grades 1-12 in Washington state to determine how children at various grade levels perceived males' and females' interest in using computers. A 46-item instrument was field tested using 124 students from three small school districts whose administrators had volunteered to participate. Four sections of an…

Recent technological advances and new software packages put unprecedented power for experimenting and theory-building in the hands of students at all levels. Microcomputer-based laboratory (MBL) and model-solving tools illustrate the educational potential of the technology. These tools include modeling software and three MBL packages (which are…
