These are pointers given to me during defense of dissertation:
1. Address the right audience. In other words, do not speak with a language that is stuffy, complex, or personable and simplistic unless you first identify your audience.
2. Make sure your font is over 36pt, always bullets, no paragraphs unless they are short
3. Do not use distractors such as Clip Art unless it is directly related to the presentation.
4. Always keep the title of the presentation atop each of the slides.
5. When presenting Data, make sure you triangulate it, break it down, and analyze it in separate sheets, placing the graph next to each of the analytical points.
6. Talk slow, and have a timer for each new topic. Have someone from the audience guide you or move your slides at the time you both agree. give at least 30 seconds for the slide and the information to filter through.
7. Don't forget the natural flow of the presentation. One slide should be a continuation of the one previous. Do not jump around.
8. Always keep a "parking lot" on the back. If anyone has observations or questions, they can write them on a sticky note and place it on a large piece of paper which you will title "Parking LOT" and tell everyone that all their questions/comments should go there and you will address them at the end.Tell them to specify which slide they referred to.
9. During your Q and A you will move to the parking lot to read out questions and comments.
10. Always allow for a 7-10 minute break in a presentation lasting longer than 55 mins to one hour.
**You might do an ice breaker showing the reason behind the presentation, and even offer a piece of gum (good to stimulate thinking) or candy for a start.
Hope this helps a bit!
