Our previous work interpreted single-lognormal fits to inter-gaze distance (i.e., "gaze steps") histograms as evidence of multiplicativity and hence interactions across scales in visual cognition. Bogartz and Staub (2012) proposed that gaze steps are additively decomposable into fixations and saccades, matching the histograms better and…

Skidmore and Thompson (this issue of "Educational Researcher") imply that a graph was changed with the intent to promote more experimental research in education. In this response, the author presents evidence that challenges this implication and concludes that the changed graph does not accurately capture the "declining" trend of experimental…

This article responds to arguments by Skidmore and Thompson (this issue of "Educational Researcher") that a graph published more than 10 years ago was erroneously reproduced and "gratuitously damaged" perceptions of the quality of education research. After describing the purpose of the original graph, the author counters assertions that the graph…

As a public school English teacher, the author observes standardized testing season each year with a sort of grim fascination. "So this is it," she thinks as she paces around her silent classroom, peering over kids' shoulders at articles about parasailing. Line graphs tracking the rainfall in Tulsa. Parts of speech. Functions of "x." "These are…

Graphing predictions is especially important in classes where relationships between variables need to be explored and derived. In this article, the author describes how his students sketch the graphs of their predictions before they begin their investigations on two laboratory activities: Distance Versus Time Cart Race Lab and Resistance; and…

Quantitative literacy, the ability to discriminate between good and bad data, the disposition to use quantitative information to think through complex problems are capacities that educators across fields should be helping students develop. Burke leads the reader to this conclusion through an extended example of income distribution, clarified and…

Reviews Trueswell's weeding technique, introduces possible application areas, and addresses a number of popular misconceptions. (Author)

Discusses the importance of accurate graphic presentation and describes graphs available on "LabQuest" computer software. Highlights include graphing conventions; prerequisites for computer graphing; bar graphs; pie graphs; stacked bar graphs; line graphs; x/y graphs; scatter graphs; box plots; stem and leaf graphs; best fit graphs; and…

Explains the basics of isotopic dating methods and the use of isotopic dating methods in geochronology. Presents irrelevant discussions of a creationist's views on Isochrons. (YDS)

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…

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…

Suggests that new computer software enables writers and technicians to compose graphs that rival those made by professionals. Suggests that professional and novice users of such software either intend to distort data and manipulate readers or do so out of ignorance. Describes and illuminates seven types of distortion in graphs. (PA)

William Playfair's pie chart is more than 200 years old and yet its intellectual origins remain obscure. The inspiration likely derived from the logic diagrams of Llull, Bruno, Leibniz, and Euler, which were familiar to William because of the instruction of his mathematician brother John. The pie chart is broadly popular but--despite its common…

Notes that presence of heterogeneous regression slopes in an analysis of covariance design is equivalent to presence of interaction in randomized-blocks design. Describes modification of the usual graphical representation of heterogeneous regressions that can aid in interpreting significant regions for regression surfaces. (NB)
