Creating a Plus or a Minus for a Presentation

2. Introducing/Referencing AVs

3. Common Errors AV does not explain concept
AV contains contrary information
AV is confusing, incomplete
AV detracts from presentation
Appearance
Use/Misuse by presenter
Error in AV- figures, spelling, etc.

4. Concept Errors
Information does not further or reinforce concept presented. Presenter says “this chart explains the trend etc,” and the AV doesn’t explain it, there is just a graph.
To make the AV effective- WATCH YOUR VERBS.

5. Clarifying Concepts with AV Use
If the AV is just to illustrate a graph, say “shows” not “explains” OR (even more effective) explain your graph orally after you refer to it.
Be sure that the concept you are explaining and the AV illustration you are using to clarify it matches (don’t point to a graph illustrating water rates and talk about stream pollution).

6. Contrary Information
Proofread both your presentation and your AV- if speaker says “ based on a population of 3 Million”, and your AV illustrates 5 Million, all of your information is suspect.
This may markedly affect your credibility.
It may also influence your audience’s opinion of your preparation.

7. Confusing/Incomplete AVs
Can be due to content- it’s just not there, or it’s phrased strangely, or it’s wrong, or it’s in variance with the oral content.
Can be due to layout, or to use by the presenter.

8. AVs That Detract It’s supposed to be an aid, not a detriment
Detraction can be due to
Where or how it is situated even before use
How it is used by the speaker (both during and after referring to it)
How it is laid out- structure, color, general appearance, misspellings

9. Illustration Use

10. Charts

11. How Much is Too Much? Don’t go overboard with Special Effects-
3 D, shadowing, graphs, pie charts
Remember that an AV clarifies, not confuses
Plan colors and layout
Make sure to illustrate important topics
Make sure AV tracks with your oral content
