  1. DO’s & DON’Ts of a Good TalkGarrett Ito, GG410/610, University of Hawaii Content and Structure (Big picture) Presentation mechanics (image design, timing etc) Performance (body language, voice, speaker audience rapport, answering questions) Preparation (know your audience, know your equipment, practice, practice, practice) • Explain • Convince • Entertain

  2. Content How much do you remember from a talk? Choose 2-3 points that you really want to make, and build the talk around them. Be stingy about the breadth of information covered.

  3. Structure (i.e., your good science) Introduction: what’s the scientific problem? Methodology: how to address the problem Results/Findings of Method Interpretations of Findings Conclusions: answers to the problem

  4. Structure (i.e., your good science) Introduction: what’s the scientific problem? -clearly defines the problem/question/hypothesis -outlines what’s to come (method & sometimes even conclusions) Methodology: how to address the problem Results/Findings of Method Interpretations of Findings Conclusions: answers to the problem

Content and Structure (the vitals) Presentation mechanics (image design, timing etc) Performance (body language, voice, speaker audience rapport, answering questions) Preparation (know your audience, know your equipment, practice, practice, practice)

  6. Structure (i.e., your good science) Introduction: what’s the scientific problem? -clearly defines the problem/question/hypothesis -outlines what’s to come (method & even conclusions) Method: how to address the problem Results/Findings of Method Interpretations of Findings Conclusions: answers to the problem

  7. Structure (i.e., your good science) Introduction: what’s the scientific problem? -clearly defines the problem/question/hypothesis -outlines what’s to come (method & even conclusions) Method: how to address the problem -data, experimental design, theory, analyses Results/Findings of Method -quantitative/objective products of method Interpretations of Findings -what can be inferred about the earth from results? -what should not be inferred (i.e., limitations)? Conclusions: answers to the problem -reiterate problem, summarize results, 2-3 conclusions • Explain • Convince • Explain

  8. Essential Elements: Explain Convince Explain Well-defined problem/objectives Clearly described methods. Logical interpretations. Convincing Conclusions Now for the “Icing on the Cake”: Presentation Mechanics & Speaker Performance Entertain

  9. Presentation Mechanics: Timing... Introduction: what’s the scientific problem? (1-2 minutes) -clearly defines the problem/question/hypothesis -outlines what’s to come (method & even conclusions) Method: how to address the problem (2-4 minutes) -data, experimental design, theory, analyses Results/Findings of Method(2-4 minutes) -quantitative/objective products of method Interpretations of Findings(2-4 minutes) -what can be inferred about the earth from results? -what should not be inferred (i.e., limitations)? Conclusions: answers to the problem (1 minute) -reiterate problem, summarize results, 2-3 conclusions

  10. Presentation Mechanics: Timing... Introduction: what’s the scientific problem? (1-2 minutes) -clearly defines the problem/question/hypothesis -outlines what’s to come (method & sometimes even conclusions) Method: how to address the problem (2-4 minutes) -data, experimental design, theory, analyses Results/Findings of Method(2-4 minutes) -quantitative/objective products of method Interpretations of Findings(2-4 minutes) -what can be inferred about the earth from results? -what should not be inferred (i.e., limitations)? Conclusions: answers to the problem (1 minute) -reiterate problem, summarize results, emphasize 2-3 conclusions

  11. Timing... Introduction: what’s the scientific problem? (1-2 images) Methodology: how to address the problem (2-3 images) Results/Findings of Method(2-3 images) Interpretations of Findings(2-3 images) Conclusions: answers to the problem (1 image) ------------------------------------------------------------------------------ At ~1 minutes per side you’ll have about 12 slides total 12 minutes is perfect. Never, never, ever, exceed 14 minutes

  12. Visuals... • There are more ways to get visuals wrong • than there are grains of sand on the beach. • Keep them simple!

  16. Fundamental equations If the radius of the channel is assumed to be large, such that and vertical velocity , and H is sufficiently small compared to the channel width W, then the governing equations reduce to: where is the stream function of the secondary flow and ε is the eddy viscosity. When equation (2) is integrated under the boundary conditions of at z = 0 and H, and at z = 0 and H, the solution is: where and are known functions of z/H and R is the radial cylindrical co-ordinate. It is necessary to observe the profiles corresponding to and , and then to calculate their difference following the inclusion of a small value for . Here, we assign a value of , such that the downstream and radial components of the flow have the vertical profiles shown in Figure 1. The introduction of a specific small value for the non-dimensional parameter has been undertaken solely to apply a uniformity to the results, and ensure that the profiles of and can be represented by single curves. “Whats wrong with this picture?”

  17. If the slide contains a lot of text – it is very tempting to read it all out word for word and while you do this you forget that your audience can read to themselves a lot faster than you can read the slide aloud so by the end they are getting pretty bored waiting for you to finish

  18. We’re limited to a dozen slides so….

  19. Its usually better to reduce the content….

  20. Allowing your audience to absorb as you build….

  21. And build….

  22. And develop the relations you wish to show.

  23. But then again, when you slowly reveal

  24. But then again, when you slowly reveal your slides line by line

  25. But then again, when you slowly reveal your slides line by line you are telling your audience

  26. But then again, when you slowly reveal your slides line by line you are telling your audience that you do not trust them to think

  27. But then again, when you slowly reveal your slides line by line you are telling your audience that you do not trust them to think just coercing them

  28. But then again, when you slowly reveal your slides line by line you are telling your audience that you do not trust them to think just coercing them to your own limited imagination

  29. But then again, when you slowly reveal your slides line by line you are telling your audience that you do not trust them to think just coercing them to your own limited imagination as well as conducting

  30. But then again, when you slowly reveal your slides line by line you are telling your audience that you do not trust them to think just coercing them to your own limited imagination as well as conducting coy, tantalising

  31. But then again, when you slowly reveal your slides line by line you are telling your audience that you do not trust them to think just coercing them to your own limited imagination as well as conducting coy, tantalising visual striptease!

  32. Appropriate Image Proportioning…

  35. Black and white can be adequate....

  36. Colors can distinguish, emphasize, clarify…

  37. IF they are used APPROPRIATELY!

  38. DO’s & DON’Ts of a Good TalkGarrett Ito, GG410/610, University of Hawaii Content and Structure (Big picture) Presentation mechanics (image design, timing etc) Performance (body language, voice, speaker audience rapport, answering questions) Preparation (know your audience, know your equipment, practice, practice, practice) • Explain • Convince • Entertain

  39. Performance • Movement • Hand gestures • Moving around can reach out • No nervous tics • Voice • PROJECT • Vary pitch, vary speed • Punctuate with pauses • Attitude • Be natural • Be enthusiastic • Smile

  40. Pointing specifies & focuses attention

  41. Speak accurately. 12 minutes is not time for meaningless words/non-words… “Uhhh” “Like” “Uhmm” “Ya-know”

  42. Answering Questions •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)

  43. Preparation Rehearsal • 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 Timing When the red light goes on, the audience stops listening – they are just wondering how you will be cut off and when.

  44. Preparation Know your audience Know your venue and equipment Check: projectors pointer microphones platform By the way, its ok if your colors do not appear exactly as you do on your laptop. If you must mention so, do it only once & move on!

  45. Don’t sweat it if your not perfect. But to strive for Greatness… Focus first on the essentials: Good scientific structure: clear problem/objectives, method, interpretations, conclusions Tell them what you are going to tell them, tell them, then tell them what you told them Explain, Convince, Explain Then there’s the mechanics & performance Keep your visuals visible, visual, and simple. Speak audibly, clearly, and deliberately Practice, practice, practice! Entertain
