PowerPoint is a popular program, and others will be needing computer time also. If you haven't used PowerPoint before, don't wait until the week before your presentation to learn it. You don't want glitzy backgrounds and fancy slide transitions to distract your audience from the content of your talk. Turn off any sound effects. Use good taste in selecting backgrounds, colors and fonts, and apply them consistently throughout the presentation.
Presentation Find an appropriate rate and level for speaking.
Try not to speak too fast or too slow, too loudly or too softly. Maintain good eye contact with the audience. Do NOT read your presentation Keep in mind that written sentences are very different from spoken sentences. Use an outline of main points rather than a written text to prompt you during the talk. When giving a computerized presentation, use the mouse to point out the specific regions of a slide as you discuss them.
