Too Much Text

  – Instead of one slide

• He had the knack
• But lacked the cheek
• To get one back
• Burma-Shave
Too much text
 Following the nomenclature presented by Rahmani in his
 1989 paper, coal horizons are labeled from 0 to 6.
 Thickness of the coal seams varies from a few centimeters
 to approximately 1.4 m. Coals are rarely over 1 m thick,
 which may lead to problems with seismic resolution. Locally,
 the coals may form a sharp conformable contact with
 underlying sandstones, or may be eroded by overlying
 channel sandstones. Most of the coals over the section,
 however, are associated above and below with grey-brown,
 carbonaceous siltstones and shales.

 Near the West end of Willow Creek, the lowermost unit is
 sandy channel fill, overlain by coal 0, interbedded with
 carbonaceous siltsone and shale. Coal 1 is in sharp contact
 with the underlying white sandstone, and coal 3 lies above
 brown, planar-bedded silty sandstone and shale.
Better Use
• 6 coal seams, numbered 0 to 6
  (Rahmani, 1989)
• Thickness up to 1.5 m, often <1 m
• Usually surrounded by grey-brown
  siltstones/shales
• Locally may cut into or be eroded by
  sandstones
Using Graphics
Why use graphics?
• Enhance presentation
• Worth a thousand words…
• Not substitute for content
• Bells and whistles
• Can be distracting
• Ask yourself ―why?‖
  – Glitz
  – Helps
Guidelines/Suggestions
• Make focal point of slide
• KISS
• Avoid splashy
• Splashy graphics can distract
• Make your own
Guidelines/Suggestions
• Give credit for ―borrowed‖ images
• Use only when needed
• Use quality graphics
• Maximize size
Use of graphics
                  • Pay raises for all
                  • More students

Backgrounds
• Keep them simple (KISS)
• Distracting?
• Create your own
• Find others:
  – Clip art services
  – Google Images
• Make sure text can be read
Poor Background Choice
Another Poor Choice
Better Choice
Fancy Backgrounds
• Fancy backgrounds distract from text
• Try to fade photos so text is more visible




• Eliminate other background features (like
  lines) if you have a photo background

Selecting a Color Scheme
• Dark backgrounds: light text
• Light backgrounds: dark text
• Test your colors with projection
  (Red on Blue looks OK on your
  computer, BAD on a big screen)
• DON’T use Red & Green (Someone
  won’t be able to read it!)
• Colors are used for emphasis
Special Effects
• Options: build effects, transition effects,
  animations, sounds
• Fun but distracting
• Creates larger files, longer load times
• Ensure projection computer has
  components installed
What’s next?
What’s next?
• Remember why we lecture
• Look at how you use PowerPoint
• What one thing can you do differently
• Build and change slowly
• Enhance slowly
• Have some fun
  Break
   The
  Rules!!!!
It can be fun :)
