4. The defaults of PowerPoint are not based on research in communication or cognitive psychology [Gomes, 2007] Poor starting place

5. Our research has found that most slides are heavily influenced by these defaults [Garner et al., 2009] Too much text 40%

6. Our research has found that most slides are heavily influenced by these defaults [Garner et al., 2009] Too much text: crowded 25%

7. The past few years, this common practice of PowerPoint has received harsh criticism [Tufte, 2003] [Schwartz, 2003] [Keller, 2003] January 16, 2003 February 1, 2003 January 24, 2003

8. Several recent texts have challenged the defaults of PowerPoint 2003 2005 2008

9. We advocate an assertion–evidence slide structure that is grounded in communication research [Fishbone, 2008]

10. Xenon headlights illuminate signs better than halogen headlights do [Sylvania, 2008 ] Xenon Headlight Halogen Headlight SilverStar Ultra TM Standard Halogen Xenon

11. [Sawarynski, 2009] The structure calls for a succinct sentence headline that states the main assertion of the slide [Toulmin, 2002] [Alley et al., 2006]

12. The small size of the mouse brain makes locating specific areas extremely difficult [Welker, 2008]

13. The structure also calls for supporting that sentence-assertion headline with visual evidence [Mayer, 2001] [Paivio, 1986] [Brown, 2008]

15. The Chesapeake Bay, which is the country’s largest estuary, has only two places for traffic to cross [landsat.gsfc.nasa.gov] Dover Washington D.C Richmond Annapolis sha.state.md.us [roadtraffic-technology.com]

16. In the past 25 years, traffic has significantly increased on the Chesapeake Bay Bridge 1961 Traffic 1.5 million [Maryland Transportation Authority, 2007] 1952 Traffic: 1.1 million 2007 Traffic: 27 Million

17. How much power from a truck’s engine is needed to overcome aerodynamic drag? 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 [LLNL, 2010]

18. A third hurdle in adopting the assertion−evidence structure is to overcome the weak defaults of PowerPoint [Alley, 2003] [Atkinson, 2005] Template at first Google listing for “presentation slides”

19. In summary, assertion-evidence slides are more effective than the common practice of PowerPoint [Hamaker, 2009]
