Discusses the construction of logarithmic and arithmetic scales illustrates why they should be used, and demonstrates the difference between them. Offers suggestions for classroom applications of the scales. (FL)

The paper describes how "IBM Graphing Assistant" and "Apple Softgraph" can foster a multifaceted approach to application of mathematical concepts and how a survey can be undertaken using the computer as word processor, data bank, and source of visual displays. Mathematical skills reinforced include estimating, rounding, graphing, and solving…

Twenty-four braille readers (grades 4-12) performed a line-tracking task on tactile line graphs which differed in the type of raised line used to represent the data curves and natures of the display backgrounds. Grids impaired the trackability of every line tested, while line type and grade level had only marginal effects. (Author/CL)

Three solutions to the problem of treating compiled statistical data graphically are proposed. The first is based on the concept of index number and the other two are based on component-bar graphs. (2 references) (Author/NH)

Reports three experiments conducted to investigate factors controlling performance of nonreinforced verbal imitation. (WY)

Uses charts and graphs to illustrate rising college construction costs. Offers information on expenses State-by-State and on average per-square-foot costs. (LR)

Argues that tables, graphs, and diagrams extend language's power by exploiting the Euclidean possibilities which a text suggests. Notes that graphic display elements form no compatible natural set and that their value and visual elements are decisively disparate. Concludes that graphic displays are unlikely candidates for unitary theoretical…

Describes research that investigated a method of automatically generating concept association maps that could be useful to abstractors. The use of word stems as concept surrogates, cooccurrence to define concept links, and a general-purpose graph-drawing algorithm is described; and results of evaluation of two link selection methods are reported.…

Treats visuals as sites of power inscription. Advances a Foucauldian design model based on the Panoptican--Jeremy Bentham's architectural figure for empowerment based on bimodal surveillance. Notes that numerous examples serve in demonstrating that maximum effectiveness results when visuals foster simultaneous viewing in the two panoptic modes,…

Discusses knowledge graphs, a new form of knowledge representation, and their possible uses in electronic study books. Topics addressed include graph structures; semantics; and representing knowledge from books, including browsing, information marking, annotations, group-based learning, information sequencing, information distribution, and…
