How much text is appropriate for each slide?

About as much as they can read in ~1 minute.AND it helps to support text with images.

What about Colors? Black and White can be adequate

Use colors to distinguish, emphasize, clarify, & add a bit of life

IF they are used APPROPRIATELY!

Keep ‘em tasteful and professional

What about Powerpoint Animations and Tricks?

Use them to add a “bit” of variety, illustrate a point, &/or for emphasis. For example…..

But its better to error on the conservative so as not to cause a DISTRACTION

Speaker PerformanceVoice

•PROJECT

•Vary pitch, vary speed

•Punctuate with pauses (avoid monotone)

Movement

•Use deliberate hand gestures

•Moving around to reach out to audience

•Minimize nervous tics

Attitude

•Be natural

•Be enthusiastic

•Smile

Occasional Humor Helps

Pointing specifies & focuses attention

Systematic Fault Patterns on Earth

Speak accurately. 12 minutes is not timefor meaningless words/non-words…

“Like”

“Ya-know”

“Uhhh”

“Uhmm”

•Repeat or summarize the question; if needed, paraphrase it to your advantage

•Answer simple factual questions right away

•Never bluff. If a question comes up that you cannot answer, say so… strategically.

“I’ll have to give that some more thought….”

“Good question, I hadn’t thought of it in that way before. Lets have a beer and discuss this further.” (they might even buy you one)

Answering Questions

Preparation

Practice/Rehearse

• until the timing is right• until you know exactly what you are going to say with each slide• but do not over-rehearse so you loose your flare

Preparation

Know your audience

Know your venue and equipment

Check:

projectors

pointer

microphones

platformBy the way, its ok if your colors do not appear exactly as you do onyour laptop. If you must mention so, do it only once & move on!
