[Alley, 2013] Teaching Slides: Part I The Craft of Scientific Presentations Michael Alley College of Engineering Pennsylvania State University [estevejobs.com] [TED.com]

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

[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

[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]

Slides influence the preparation, delivery, and understanding of a scientific presentation [Alley, 2013]

[estevejobs.com] A key assumption is that slides are needed for that part of the presentation [Alley, 2013]

Beginnings prepare the audience for the work pre-combustion methods post-combustion methods combustion methods [Alley, 2013]

Success involves defining a valuable scope and a satisfying depth unknown Valuable Satisfying [Alley, 2013]

A common error in the beginning of scientific talks is to leave the audience behind [Alley, 2013]

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-Ålesund [Alley, 2013]

A common error in the mapping of scientific talks is to show a list that is not memorable [Alley, 2013]

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

[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]

Another assumption is that the slides we project should differ from our handout ≠ [Alley, 2013]

PowerPoint’s defaults arose before much research on slides and have not changed significantly [Gomes 2007] [Alley, 2013]

PowerPoint’s defaults run counter to how people learn Does not filter noise Leads to too many words Consumes valuable space [Garner et al., 2009]

[Alley, 2013] The assertion–evidence structure consists of a message headline supported by visual evidence [Settles, 2002] [Alley, 2013]

scent source The way a dog sniffs does not contaminate the vapor stream from the scent source [Settles et al., 2002]

[Alley, 2013] scent source The way a dog sniffs does not contaminate the vapor stream from the scent source [Settles et al., 2002]

[Alley, 2013] The first step is to write a sentence headline that states the main message of the slide sentence headline

[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]

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]

[Alley, 2013] The second step is to find or create visual evidence that supports the sentence headline visual evidence [Alley, 2013]

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] At typical highway speeds, overcoming drag requires about two-thirds of a truck engine’s output [McCallen, 2004] Aerodynamic Drag C D = 0.6 Rolling Friction and Accessories

[Alley, 2013] ≠ Another assumption is that the slides that we project are for our audience, rather than for us

[Alley, 2013] The third step in creating assertion-evidence slides is to change the defaults of PowerPoint

[Alley, 2013] Before: Tsunamis cause devastating destruction, especially to sparsely vegetated areas Indian Ocean Tsunami: Gleebruk Village, Sri Lanka After: PPT’s defaults crowd this slide

[Alley, 2013] 2004 Indian Ocean Tsunami: Gleebruk Village, Sri Lanka Before Tsunamis cause devastating destruction, especially to sparsely vegetated areas After [homepage.mac.com/demark/] Sparse

[Alley, 2013] A common error in the endings of scientific talks is to waste the last slide [Alley, 2013]

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

[Alley, 2013] Many engineers and scientists have had success using the assertion-evidence approach writing.engr.psu.edu/speaking.html

[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

In summary, to excel in your presentations, you will need content, passion, and an acute sense of audience [ [ted.com] [
