A
Answer to Question 2
Follow these guidelines when preparing for your presentation:
(a) Prepare thoroughly. You can expect a degree of nervousness as you anticipate speaking before a group. This natural tension is constructive because it increases your concentration and your energy and enhances your performance. However, even those seasoned to the spotlight can experience a debilitating case of the jitters.
(b) Prepare effective presentation support tools. Follow the guidelines presented in the preceding section to select and design visuals, handouts, and notes pages appropriate for your audience and purpose.
(c) Practice, but do not rehearse. Your goal is to become familiar with the key phrases on your note cards so that you can deliver the presentation naturally as if you are talking with the audience-not reciting the presentation or acting out a role.
(d) Spend additional time practicing the introduction and conclusion. You will want to deliver these important parts with finesse while making a confident connection with the audience.
(e) Seek feedback on your performance to help you to polish your delivery and improve organization. Critique your own performance by practicing in front of a mirror and evaluating a recording of your presentation.
