Five basic parts of effective presentations:: 

Five basic parts of effective presentations: 1. Planning 2. Organization 3. Construction 4. Delivery 5. Question and Answer

1. Presentation Planning: 

1. Presentation Planning What is the objective of the presentation Who is the audience How large is the audience Where is presentation to be given What resources are available How much time do you have Ask Questions

2. Organization: 

2. Organization Carefully outline your presentation before getting into construction details Organize around effective visual aids Careful use of humor Organize presentation with: introduction body conclusion

Types of Visual Aids: 

Types of Visual Aids Chalkboards Overhead transparencies Posters and flip charts 35 mm slides Paper handouts Physical models Videotape, film Computer projection ISSUES: Cost Lead Time Flexibility Visibility Attractiveness

3. Construction: 

Start with a detailed outline Appearance is EVERYTHING Allow at least one minute for each slide Minimize the number of lines of text and the number of graphs shown on each slide. More than 12 lines of text or 5 curves are too many. Too little is better than too much. Put a frame or border around each slide Use landscape, not portrait orientation 3. Construction

3. Construction - continued: 

3. Construction - continued Mix modes - a slide completely filled with text or equations is BORING ! Intersperse pictures or graphics wherever possible to catch reader’s eye

Construction - continued: 

Construction - continued Text must be large enough to be visible. (this is a 28 point Garamond font) This is BOLD (for comparison, this is a 12 point Times Roman font) Use the 'Floor Test' DO NOT make transparencies directly from pages in books, reports or papers unless they can be enlarged Light text on dark background is very effective Don’t get carried away with fonts and colors

4. Delivery: 

4. Delivery Mechanics Eye contact Cue cards or script if desired Variation (media, voice, position, ...) Voice Speak clearly, distinctly To audience, not screen Proper tempo Avoid monotone delivery Posture

4. Delivery - continued: 

4. Delivery - continued Professional Demeanor Confidence: If you want to persuade the audience to accept your message, you must show confidence (but not arrogance) in yourself and your work. Respect your audience - don’t insult them Approach: your purpose is usually to inform or persuade, not to baffle and confuse. People are always more impressed with a clear presentation than with one they cannot understand or which makes them feel stupid. Dress to the level of the most important audience member Know your subject and be excited about it !

4. Delivery - continued: 

4. Delivery - continued Practice Know your surroundings and equipment Dry run for a test audience and solicit constructive feedback Test your equipment first Color schemes which look good on the computer monitor may look yuckie when projected Time - keep to a schedule Have a backup - if using computer technology, always bring standard transparencies just in case Murphy strikes

5. Question and Answer: 

5. Question and Answer Observe diplomacy and tact people ask questions for a variety of reasons, not necessarily to get further information. Above all, don’t lose your cool or get defensive. Keep on track repeat the question for benefit of the audience and to make sure you heard it right (this also helps you organize your thoughts). Answer the question. Do not elaborate unless asked to do so.

5. Question and Answer - continued: 

5. Question and Answer - continued Watch assertions 'In my opinion..' only works if you are qualified to give an opinion. Defer to facts and resources when possible. Don’t lie It’s unethical ! Assume that the audience knows everything about the topic -- if you lie and get caught, they’ll kill you. If you don’t know don’t be afraid to say 'I don’t know'. Tell the questioner that you do not have the answer right now but you would be happy to look it up, or discuss the concept with him or her at a later time.
