Zoller, who provides professional learning seminars and speaks on facilitation and presentation skills and leadership, and Landry, an elementary school principal who gives professional and organizational development workshops and presentations, outline seven attributes of effective presenters that can enhance the learning of participants. They detail the patterns of communication that effective presenters use, including verbal and nonverbal communication, and methods for establishing credibility; building and sustaining rapport; reading the group; balancing task, process, and group development; listening to and acknowledging participants; responding appropriately; and recovering with grace. They do not discuss creating or preparing a presentation. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
