Using PowerPoint as a Visual Aid
PowerPoint and similar visual representation programs can be an effective tool to help audiences remember your message, but they can also be an annoying distraction to your speech. How you prepare your slides and use the tool will determine your effectiveness.
PowerPoint is a slideware program that you have no doubt seen used in class, presentation at work, or perhaps used yourself to support a presentation. PowerPoint and similar slideware programs provide templates for creating electronic slides to present visual information to the audience, reinforcing the verbal message. You'll be able to import, or cut and paste, words from text files, images, or video clips to create slides to represent your ideas. You can even incorporate Web links. When using any software program, it's always a good idea to experiment with it long before you intend to use it, explore its many options and functions, and see how it can be an effective tool for you.
