With expanded coverage of persuasion, new end-of-chapter exercises, fully integrated technology, and new up-front material designed to get students ready to present right away, the Seventh Edition of Public Speaking is more interactive and student-focused than ever. Centered around three core objectives--preparing students for civic life, respecting the diversity of the audience, and sensitizing students to the ethical impact of their words--the text continues to offer both practical advice for public speaking and an understanding of why such advice works.The Seventh Edition introduces two models of oral communication--the Mechanical Model and the Identification Model--designed to help students better understand the elements that influence oral communication. The Mechanical Model addresses the physical and technical constraints that shape communication, while the Identification Model points out the ethical consequences of oral communication. These concepts are brought to life through examples from real, student, and professional speeches; new Discussion and Application exercises at the end of each chapter; and a variety of boxed features throughout the text. While the trusted content and distinctive features of the text have been maintained, Public Speaking, 7/e, continues to evolve and adapt to changing times and the needs of its student audience.New.
