PowerPoint Slides and Overheads
- Follow the
7 x 7 rule: maximum of seven words per line and seven lines per page. This is
one of the frequently violated rules of effective presentations.
- Use short phrases, not full sentences.
- Use a large font that your audience can see.
- Display web pages infrequently. They are not designed to be projected on
a screen and will appear as a blur to your audience. When you do choose to display
a web page carefully describe the relevant parts to your audience. Minimize scrolling.
- Handouts are useful when you have lots of text that you want your audience to read
(computer code, quotations, long lists, newspaper articles...)
- Look at your audience. You should know your material well enough that you do not
need to read it.
- It's OK to use notes, but they should contain an outline of your talk rather than
- Have fun! Humor helps keep your audience's attention.
** Demonstrate your knowledge by supporting assertions with facts. Compare
the following two examples. The first example is poorly researched, provides little
helpful information and is not convincing. The second is well researched and
the assertions are well supported.
