CHOOSING THE CORRECT AUDIOVISUAL AIDS
In this class, our presentations will take the form of a graphics program (PowerPoint). But, there
are many other audiovisual aids from which to choose when producing a presentation. Below is
a brief description of some of these choices.
ß Overheads/Transparencies
ß Chalkboards and Flip Charts
ß Audio and Audiovisual Equipment
ß Handouts
ß Computer-Generated Presentations
o Advantages-Inexpensive and easily available
o Disadvantages-Technology can fail (e.g. burned out bulb) and is now considered
“old fashioned”
o Advantages-Do not require electricity, chalkboards are “reusable”
o Disadvantages-Hard to “hide” from audience (can’t put a piece of paper over
them like an overhead) so can draw attention away from presenter
o Advantages-Can bring vivid examples to an audience
o Disadvantages-Presents chance of technical failure, requires great effort to
ensure that the audience can see and/or hear them
o Advantages-Inexpensive, don’t depend on technology for their use
o Disadvantages-Audience might focus on them and not the presenter
o Advantages-Allow for “special effects” such as computer-played video, Internet
connection, etc.
o Disadvantages-Potential equipment failure and can become “overdone” and
gimmicky
