Challenging students to educate the public about how rhetoric functions is a primary impetus of the argumentative dictionary eBook. In this author's classes, "rhetoric" means the communicative tactics and strategies used to motivate actions and beliefs. With its emphasis on open-access rhetorical pedagogy, this project and its impetus align with the "Mt. Oread Manifesto on Rhetorical Education," which calls for students to be "exposed to authentic projects and audiences that connect them to the public sphere" (Keith & Mountford, 2013, p. 3). The eBook project helps to fulfill this pedagogical goal by providing a free book that instills the importance of rhetoric to civil society, and by motivating students' competency to implement horizontal communication strategies. The designated courses include Rhetoric Studies, Discourse Studies, Persuasive Writing, Argumentation, and Rhetoric of Social Movements. Course objectives are: (1) This semester-long project requires each student to write one entry that will be compiled with their classmates' entries into an argumentative dictionary and published as an eBook. "Argumentative dictionary" means a book that defines terms, and argues about how they rhetorically function; (2) By writing argumentative dictionary entries that include definitions, historical contextualization, and mini rhetorical analyses, students will learn the fundamentals of rhetorical studies, including the rhetoric of definitions, persuasive writing, argumentation, rhetorical criticism, and discourse analysis, as well as ePublishing; and (3) Learning how to write for a public, open-access audience is emphasized.
