Clinical interviews were conducted with 25 seventh- and eighth-grade students to determine: (1) the extent to which they could produce correct graphical representations of familiar situations; (2) to what extent they could infer relationships from graphs; (3) what are the most commonly held graphing misconceptions and how stable they are; and (4)…

While the use of informational graphics in newspapers is increasing, little is known regarding how well readers can understand them and how readers use them. A study investigated whether readers of newspapers read graphics before or after they read the headline/text, and whether people decide to read a graphic device for appearance-related or…

This investigation of the encoding features of graphs begins with a description of a cognitive framework which allows designers to factor into the process of designing displays how people interpret the information found and what display properties are responsible for this interpretation. The framework also provides a performance measure for use in…

This paper outlines the development of an activity that uses the computer's unique capabilities to provide students with a meaningful and highly motivating experience with the graphing of equations. The basic design of the game calls for the computer to display a coordinate grid on which it graphs any equations that are typed in by the student.…

Perhaps because the United States is undergoing a video revolution, perhaps because of its increasing sales of goods to non-English speaking markets where graphics can help explain the products, perhaps because of the decreasing communication skills of the work force, graphic aids are becoming more and more widely used and more and more important.…
