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.

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.

Seeing Cells: Teaching the Visual/Verbal Rhetoric of Biology    

This pilot study obtained baseline information on verbal and visual rhetorics to teach microscopy techniques to college biology majors. We presented cell images to students in cell biology and biology writing classes and then asked them to identify textual, verbal, and visual cues that support microscopy learning. Survey responses suggest that these students recognized some of the rhetorical strategies used and conflated others, revealing intriguing questions for further research in undergraduate microscopy education.

A Visual and Social Analysis of Optometric Record-Keeping Practices    

This article investigates the contribution visual rhetoric and rhetorical genre studies (RGS) can make to health care education and communication genres. Through a visual rhetorical analysis of a patient record used in an optometry teaching clinic, this article illustrates that a genre's visual representations provide significant insights into the social action of that genre. These insights are deepened by an insider analysis of the patient record that highlights how content analyses of visual designs need to be elaborated by contextual considerations. A combined visual rhetoric and RGS analysis shows that clinical novices learn to interpret the record's visual cues to safely traverse the complex requirements of this apprenticeship genre. The article demonstrates that visual rhetoric research can meaningfully contribute to the understanding of genres by presenting an enriched contextual analysis achieved by consulting with context insiders.
