Presenting science is more than just
content… it’s also about style!
By Jenni Metcalfe
A good presentation is not simply a good paper well
read. It's different - in structure, content, length,
and intention. Talks are delivered at one-third the pace
that the audience can read; they cannot be re-read to
check facts; and they may make use of a variety of
visual techniques to carry or enhance the message being
conveyed.

The best presenters bring enthusiasm to their
presentations. You can forgive a presenter just about
anything if they are enthusiastic.
Presentations about science are always a battle of
Detail versus Clarity versus Time.
Speakers try to cram in too much detail, and end up
obscuring their main message or gobbling out the last
sections to finish on time (or worse - running over
time).
The MOST important part of any presentation is always
the AUDIENCE.
Good presenters start by thinking of them rather than
how they are going to fit all their scientific
information into a PowerPoint presentation.
But what makes for a good presenter?
If you look at the following list of characteristics for
effective speakers and categorise each item according to
whether it relates to content, style or visuals, you’ll
find that style is the most important element separating
an effective speaker from a less effective one. While
the substance or content is critically important, the
way it is delivered separates the great speakers from
the just OK or boring speakers. Notice that visual aids
are the least important element in an effective
presentation. But, where do most presenters start their
preparation? What do they rely on the most?

Remember
90 percent of what you say will be forgotten within 24
hours
People speak at about 150 words a minutes but think at
600-700 words a minute
People can’t remember more than five things from a
presentation – and are more likely to remember only
three |
