a. 8 adavantages of using visual aids
b. 3 warnings about using visual aids

Dinckel and Parnham (1985) say that "The great danger (in using visual aids) is that
presenters place the major emphasis on visual aids and relegate themselves to the
minor role of narrator or technician. You are central to the presentation. The visual
aid needs you , your interpretation, your explanation your conviction and your
justification.

Visual aids can make information more memorable and they help the speaker.
However, they must literally support what the speaker says and not simply replace
the spoken information. It is also not enough to just read text from a visual aid.

There are many advantages of the correct use of viaual aids. They can show
information which is not easily expressed in words or they can highlight information.
They caus ethe audience to employ another sense to receive information, they bring
variety and therefore increase the audience's attention. They save time and they
clarify complex information.
