 During the presentation facts must be enumerated in sequential
steps, each step firmly founded on the previous one.
 Remember that your labyrinth of knowledge, with its familiar
shortcuts, alternate routes and interconnections is unfamiliar to
the audience listening to your story for the first time.
 To communicate effectively, avoid the use of hyperbole and
jargon whenever possible!
 Speech reflects our thought processes, and an imprecise
speaker is often an unfocused thinker.
 You should carefully analyze the often fuzzy borders that
separate experimental evidence from speculation. The care with
which this intellectual process is performed is reflected in the
manner in which you formulate your sentences.
 By recognizing the limits of your experiment (or theory or
explanation) and clearly defining the conditions under which your
conclusions are valid, you gain the respect and credibility of your
audience.

DELIVERY

VOICE CONTROL AND EYE CONTACT

Effective use of the voice, eye contact, posture, gestures, and
enthusiasm distinguish a routine presentation from a memorable one.
 The characteristics of delivery in terms of voice control can be
separated into several interrelated properties: sound, volume,
speed, and rhythm.
 Articulation and eye contact are the two most important
components of voice presentation. Take the time to articulate
every work of each sentence clearly, while maintaining eye
contact with your audience.
 As with written text, the end of the sentence designates the
"stress" position. It is here the audience expects to be provided
with the most important information.
 Nervous, hurried speech often leads to inaccurate articulation.
Take your time and do not speak faster than your normal
conversational speed.
