Conclusion

To finish this chapter, we will recap and remind you about the principles of effective presentation aids. Whether your aid is a slide show, object, a person, or dry-erase board, these standards are essential:

• Presentation aids must be easily seen or heard by your audience. Squinting and head-cocking are not good reactions. Neither should they look at the screen the whole time and ignore the speaker.
• Presentation aids must be portable, easily handled, and efficient.
• Presentation aids should disappear when not in use.
• Presentation aids should be aesthetically pleasing, which includes good taste. Avoid shock value just for shock value. You might want to show pictures of diseased organs and teeth, deformities, or corpses for your speech to make a point, but context is everything. Will your audience react so strongly that the overall point is missed? Additionally, electronic media today allows you to create very “busy” slides with a variety of fonts, colors, collages of photos, etc. Keep in mind the principles of unity and focal point.
• Color is another aesthetic aspect. Some colors are just more soothing, readable, and appropriate than others. Also, the color on your slides may be different when projected from what is on your computer. Finally, presentation aids must support your speech and have high relevance to your content.
