Presentations Michael Alley College of Engineering Pennsylvania

Slide 2
[Alley, 2013] To excel in your presentations, you will need
content, passion, and a keen sense of the audience

Slide 3
[Alley, 2013] audience purposeoccasion You begin preparing a
scientific presentation by analyzing your constraints what they
knowwhy they are there to inform to persuade time room
Slide 4
[Alley, 2013] * To excel in your scientific presentations, you
guide your audience up the mountain of your work Orienting audience
at the start Keeping audience on the path Appreciating the view
[Alley, 2013]
Slide 5
Slides influence the preparation, delivery, and understanding
of a scientific presentation [Alley, 2013]
Slide 6
[estevejobs.com] A key assumption is that slides are needed for
that part of the presentation [Alley, 2013]
Slide 7
Beginnings prepare the audience for the work pre-combustion
methods post-combustion methods combustion methods [Alley,
2013]
Slide 8
Success involves defining a valuable scope and a satisfying
depth unknown Valuable Satisfying [Alley, 2013]
Slide 9
A common error in the beginning of scientific talks is to leave
the audience behind [Alley, 2013]
Slide 10
Determining Whether Atmospheric Mercury Goes into Surface Snow
after a Depletion Event Katrine Aspmo Torunn Berg Norwegian
Institute for Air Research Grethe Wibetoe University of Oslo, Dept.
of Chemistry June 16, 2004 Event Ny-lesund [Alley, 2013]
Slide 11
A common error in the mapping of scientific talks is to show a
list that is not memorable [Alley, 2013]
Slide 12
This talk traces what happens to mercury after it depletes from
the atmosphere in arctic regions Environmental implications
Measurements from Station Theory for mercury cycling
Slide 13
[Alley, 2013] * To excel in your scientific presentations, you
guide your audience up the mountain of your work Keeping audience
on the path [Alley, 2013]
Slide 14
Another assumption is that the slides we project should differ
from our handout [Alley, 2013]
Slide 15
PowerPoints defaults arose before much research on slides and
have not changed significantly 1987 2003 2007 [Gomes 2007] [Alley,
2013]
Slide 16
PowerPoints defaults run counter to how people learn Does not
filter noise Leads to too many words Consumes valuable space
[Garner et al., 2009]
Slide 17
[Alley, 2013] The assertionevidence structure consists of a
message headline supported by visual evidence [Settles, 2002]
[Alley, 2013]
Slide 18
scent source The way a dog sniffs does not contaminate the
vapor stream from the scent source [Settles et al., 2002]
Slide 19
[Alley, 2013] scent source The way a dog sniffs does not
contaminate the vapor stream from the scent source [Settles et al.,
2002]
Slide 20
[Alley, 2013] The first step is to write a sentence headline
that states the main message of the slide sentence headline
Slide 21
[Alley, 2013] A succession of electron acceptors occurs when an
aquifer becomes contaminated with oil CH 4 SO 4 2 Fe 3+ NO 3 Mn NO
3 Mn 4+ O2O2 O2O2 Oil Flow [Alley, 2013]
Slide 22
A data acquisition system changes the form of the data A
digital acquisition system has to sample at a rate fast enough to
retain the shape of the analog signal Analog-to-Digital Converter
Measurement Device [Alley, 2013]
Slide 23
A digital acquisition system has to sample at a rate fast
enough to retain the shape of the analog signal Analog-to-Digital
Converter Measurement Device
Slide 24
[Alley, 2013] The second step is to find or create visual
evidence that supports the sentence headline visual evidence
[Alley, 2013]
Slide 25
Most streams were classified in fair condition because of high
chloride concentrations Delaware River Parks: 79% Fair Chloride
caused most problems Western Pennsylvania Parks: 75% Fair Chloride
caused most problems West Virginia Parks: 48% Fair Sulfate caused
most problem

[Alley, 2013] Since its construction in 1952, traffic across
the bridge has grown exponentially 1952 1.1 million vehicles
[Maryland Transportation Authority, 2007]
Slide 27
[Alley, 2013] Since its construction in 1952, traffic across
the bridge has grown exponentially 1961 1.5 million 1952 1.1

Slide 30
[Alley, 2013] At typical highway speeds, overcoming drag
requires about two-thirds of a truck engines output [McCallen,
2004] Aerodynamic Drag C D = 0.6 Rolling Friction and
Accessories
Slide 31
[Alley, 2013] Another assumption is that the slides that we
project are for our audience, rather than for us
Slide 32
[Alley, 2013] The third step in creating assertion-evidence
slides is to change the defaults of PowerPoint
Slide 33
[Alley, 2013] Before: Tsunamis cause devastating destruction,
especially to sparsely vegetated areas. 2004 Indian Ocean Tsunami:
Gleebruk Village, Sri Lanka After:

Lanka Before Tsunamis cause devastating destruction, especially to
sparsely vegetated areas After [homepage.mac.com/demark/]

Slide 35
[Alley, 2013] A common error in the endings of scientific talks
is to waste the last slide [Alley, 2013]
Slide 36
Adsorbed HOAc allows the growth of siderite A thick siderite
layer protects the steel from corrosion Questions? In summary, high
concentrations of acetic acid help protect steel from corrosion
Steel Fe 3+x O 4-y FeCO 3
Slide 37
[Alley, 2013] Many engineers and scientists have had success
using the assertion-evidence approach

Slide 38
[Alley, 2013] In scientific presentations, speakers fashion
most words on the spot, but after planning and practice Memorized
Read Impromptu Fashioned on spot after planning
Slide 39
[Alley, 2013] In her TED talk, Patek focused on the content and
her passion for the ideas Sheila Patek [TED.com] [Alley, 2013]
Slide 40
Hans Rosling Passion leads to preparation which then leads to
confidence [ TED.com ] [Alley, 2013]
Slide 41
In summary, to excel in your presentations, you will need
content, passion, and an acute sense of audience [www.psyclops.com]
