“This Web site responds to the need for practical application of rhetorical principles in science and organizational communication. The site offers instructors of technical and professional communication a tool that allows them to bring concrete examples that illustrate rhetorical principles into the classroom. Using the Challenger disaster as the case study and theme, the site provides the social, political, and technical context of the disaster to help develop understanding of the background and exigence of the situation.” (Association of Teachers of Technical Writing)
