Drawing Words from the Wrong Well
Critical Error 2

Four Sources of Speech
Speaking from points Memorizing Reading Speaking off the cuff
![Page 5: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/5.jpg)
Speaking from Points
Advantages– Credibility earned– Ease of adjusting speech– Eye contact– Natural pace
Disadvantages– Wording not exact– Long prep time
![Page 6: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/6.jpg)
Memorizing
Advantages– Precision– Smooth delivery– Credibility earned– Eye contact
Disadvantages– Potential for disaster– Unnatural pace– Inability to adjust speech– Long prep time
![Page 7: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/7.jpg)
Reading
Advantages– Precision– Smooth delivery
Disadvantages– Credibility undercut– Lack of eye contact– Unnatural pace– Inability to adjust speech– Long prep time
![Page 8: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/8.jpg)
Speaking off the Cuff
Advantages– No prep time– Eye contact– Natural pace
Disadvantages– Potential for disaster– Difficulty in organizing– Lack of visual aids
![Page 9: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/9.jpg)
Appropriate Situations
Speaking from points– Conference presentation– Business meeting– University lecture
Memorizing– First few words of
presentation– Short introduction of
speaker
Reading– Press conference– Quotation– Complex wording
Speaking off the cuff– Answering a question– Asking a question

Structure: The Strategy You Choose
Chapter 3
![Page 11: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/11.jpg)
Structure of a Presentation
Organization of the major points Transitions between those points Depth the presenter achieves Emphasis of the details
![Page 12: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/12.jpg)
Structural Differences
Begin at a depth that orients the entire audience
Map the presentation for the audience Signal transitions between major parts of the
presentation

Organization
![Page 14: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/14.jpg)
Beginning
Shows the big picture of the presentation Focuses everyone’s attention to the
particular topic
![Page 15: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/15.jpg)
Middle
Discusses the topic in a logical fashion Process Chronological Event Spatial System Follow the flow Parts Grouping into parallel parts
![Page 16: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/16.jpg)
Ending
Analyze the work from an overall perspective Summary of the most important details Closure
– Set of recommendations– List of questions to be resolved– How the work affects the big picture
![Page 17: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/17.jpg)
Key Transitions

Emphasis
People remember 10% of what they hear Repetition, illustration, and placement Say something important in the beginning
– Define the scope– Importance of the work– Map the path of the presentation
Show a logical flow in the middle Leave up the conclusion slide during questions

Leaving the Audience at the Dock
Critical Error 3
![Page 21: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/21.jpg)
Anticipate Initial Questions
What exactly is the subject? Why is the subject important? What background is needed to understand
the subject? In what order will the
subject be presented?
![Page 22: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/22.jpg)
What Exactly is the Subject?
Don’t assume the audience knows what the presentation is about
Title slide (60 sec)– Title– Name of speaker– Affiliation of speaker– Key image
![Page 23: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/23.jpg)
![Page 24: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/24.jpg)

Why is the Subject Important?
Don’t move to middle until the audience understands the importance
Importance relates to money, safety, health, or environment
Curiosity: Ganymede & Callisto
![Page 26: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/26.jpg)
What Background is Needed to Understand the Subject?
Be sensitive to the background information that audiences need
If time is limited, state up front what you are assuming the audience knows
Provide background in the introduction, or as the audience needs it
![Page 27: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/27.jpg)
In What Order Will the Subject be Presented?
Reveal the organization of the presentation Use images to make mapping memorable Repeat images in the corresponding
divisions of the presentation Audience has an idea of what has
been covered and how much is left
![Page 28: The Craft of Scientific Presentations By Michael Alley](https://reader036.vdocument.in/reader036/viewer/2022062301/56813be2550346895da50fbd/html5/thumbnails/28.jpg)

Anticipating the Audience’s Bias
Understand the bias in order to decide the strategy and energy required for a successful argument
Antagonistic audience:– Define the question up front,
but don’t give away your results– Show you truly understand the
opposition’s main arguments
