This guide, designed for use by educators and interpreters, outlines principles and techniques for effective talks and discussions. Four main headings are included. The first, Introduction, describes the major premises of the guide, mainly (1) teaching is an art as well as a skill; (2) teaching involves a relationship between teacher and learner that goes far beyond the transfer of knowledge; (3) active involvement of the learner is central to good teaching; and (4) your audience may be free to leave physically or mentally. Setting the Direction, the second section, focuses on choosing objectives, audience characteristics, and deciding what to present and why. The third section, Reaching Your Audience, looks at the characteristics of talks and discussions and lists specific points on preparing both. Techniques useful for interpretation are summarized in section four. Topics dealt with include selecting and organizing the presentation, motivating and focusing the audience, getting feedback, questioning techniques, attention holding techniques, and others. A checklist and bibliography are also included. The guide is written in an informal style, with important words and phrases in bold face type, and includes many illustrations. (TM)
