Dam Visuals: The Changing Visual Argument for the Glen Canyon Dam    

Arguments manifest in scientific visuals through graphic representation, content placement, and overall document structure. These arguments, designed to influence public perception, change over time in relation to sociopolitical climate. Analysis of a series of documents constructed deliberately to influence perception can help to determine patterns of argumentation and perceived exigencies. In this article, four self-guided tour brochures produced for distribution to visitors to the Glen Canyon Dam in 1977, 1984, 1990, and 1993 are analyzed in order to identify rhetorical strategies designed to influence public perceptions of the dam site, and examine how public perception of the dam, and related argumentation, is structured by sociopolitical climate.

Drawing to Learn Science: Legacies of Agassiz    

The use of visual representation to learn science can be traced to Louis Agassiz, Harvard Professor of Zoology, in the mid-19th century. In Agassiz's approach, students were to study nature through carefully observing, drawing and then thinking about what the observations might add up to. However, implementation of Agassiz's student-centered approach has struggled with the conflict between science as a form of developing "mental discipline" in which mastery of scientific facts is the goal and science learning as a socially situated activity with an emphasis on the process of learning, not merely its products. Present-day attempts to have students draw to learn science often succumb to these same conflicts, limiting their full realization.

Florence Nightingale's Visual Rhetoric in the Rose Diagrams  

Florence Nightingale is usually pictured as an angelic nurse tending to British soldiers in military hospitals during the Crimean War. Although Nightingale was indeed a tender of soldiers, she was also an administrator, advocate for the common soldier, and proponent of the use of statistics and information design. This article examines Nightingale's rose diagrams, which she designed following her service as the director of nurses at a field hospital in the Crimean War. When the war ended, Nightingale was asked by the queen to write a report on the poor sanitary conditions and make recommendations for reform. When, after six months, the government did not act on the reforms, Nightingale decided to write an annex to the report, in which she would include her invention, the rose diagrams. Nightingale's ultimate success in persuading the government to institute reforms is an illustration of the power of visual rhetoric, as well as an example of Nightingale's own passionate resolve to right what she saw as a grievous wrong.

Graphics and Invention in Engineering Writing    

This study reports on the use of graphics by engineers as a method of stimulating the writing process (rhetorical invention). Information presented here comes from working engineers, based on a questionnaire developed after informal conversations and then administered to 15 participants in private industry, with questions about specific writing genres and types of graphics. Results show that graphics have a powerful function in stimulating writing ideas. Although individual writers' preferences in graphics are strong, patterns could be seen in (1) overall number of graphics types used by each writer, (2) specific types of graphics used by each writer based on the writing genre, and (3) the most common types of graphics used overall.

Multimodal Analysis: An Integrative Approach for Scientific Visualizing on the Web    

The Multimodal approach offers technical communicators and science writers an analytical tool to synthesize the meaning made in the connections across communicative modes. This multimodal synthesis can help technical communicators better exploit the meaning-making potential of multimodal combinations and understand the needs of future generations shaped by their increasingly developed multimodal literacy.

The Relevance of Feenberg's Critical Theory of Technology to Critical Visual Literacy: The Case of Scientific and Technical Illustrations    

Andrew Feenberg's critical theory of technology is an underutilized, relatively unknown resource in technical communication which could be exploited not only for its potential clarification of large social issues that involve our discipline, but also specifically toward the development of a critical theory of illustrations. Applications of critical theory help strengthen our discipline by forcing us to delineate extant approaches and consider whether democratic goals are being achieved through those approaches. If a critical theory of illustrations can be built from Feenberg's critical theory of technology, it should be useful for classroom instructors and researchers as well as theorists.

Scientific Illustration  

Illustrations for scientific material must convey information quickly, clearly, and succinctly. They must be technically accurate as well as aesthetically pleasing. We discuss the differences between illustrations for scientific and nonscientific material and show examples of good and poor scientific illustrations.

Contemporary Educational Psychology: Cognitive Processes in Complex Science Text and Diagrams    

Ainsworth’s (2006) DeFT framework posits that different representations may lead learners to use different strategies. We wanted to investigate whether students use different strategies, and more broadly, different cognitive activities in diagrams versus in running text. In order to do so, we collected think-aloud protocol and other measures from 91 beginning biology majors reading an 8-page passage from their own textbook which included 7 complex diagrams. We coded the protocols for a wide range of cognitive activities, including strategy use, inference, background knowledge, vocabulary, and word reading. Comparisons of verbalizations while reading running text vs. reading diagrams showed that high-level cognitive activities—inferences and high-level strategy use—were used a higher proportion of the time when comprehending diagrams compared to when reading text. However, in running text vs. diagrams participants used a wider range of different individual cognitive activities (e.g., more different types of inferences). Our results suggest that instructors might consider teaching students how to draw inferences in both text and diagrams. They also show an interesting paradox that warrants further research—students often skipped over or superficially skimmed diagrams, but when they did read the diagrams they engaged in more high-level cognitive activity.
