Guidelines for an Effective Presentation

                              Tell 'em what you're gonna tell 'em,
                                   then tell 'em,
                                        then tell 'em what you've told 'em.

1. Devices for shaping a presentation in an effective perspective
   • An informative title indicates the scope of the presentation.
   • In introduction "zoom in" to the topic. At the end, "zoom out."
2. Identify underlying questions that presentation seeks to address (for long talk, divide questions into hierarchy of subquestions); presentation is a series of answers to these questions.
3. The mainstream of the talk should address a single focus issue, tuned to the interest of the audience.
   • Omit information not directly relevant to presentation's focus
   • Keep sidetracks brief and always return to the same point.
   • Avoid backtracking.
4. Statements--constituting the mainstream of the presentation--should delineate a clear, logical line of thought.
   • Unambiguously formulate scientific concepts and methodology.
   • Avoid professional jargon.
5. End the presentation with a clearly formulated, concise conclusion. When this take-home message has been delivered, stop!

Most importantly,
          communicate with your audience -- articulation and
          eye contact -- convey enthusiasm about your work.
