2.7.4.3 Audio-visual aids in extension

The term audio-visual aid refers to anything that an extension agent uses to help to convey the message when communicating with farmers. The spoken word is the agent's main communication tool, but, whether the agent is speaking to a large village meeting or discussing a problem in a field with a group of farmers, its impact and effectiveness can be greatly increased by the use of suitable audio-visual aids. When selected and used properly, audio-visual aids can help in the following ways:

1. The interest of the audience can be maintained if the agent varies the mode of presentation. It is difficult to concentrate for long on what someone is saying; but if the agent refers to a wall chart, or illustrates a point with some slides, his audience's attention can be maintained.

2. When the information is presented to more than one sense (sight and touch, for example, as well as hearing), more is observed and it is better understood and remembered.

3. Processes and concepts that are difficult to express in words alone, can be well explained.

4. For explaining the procedure, a simple flow chart or diagram can be used and make the process clear.

5. The effects of decisions and actions that farmers might take can be shown.

6. Photographs of a particular process or procedure can give farmers a clear idea of just what it is they might be considering.

7. Pictures can have a more immediate impact on our emotions than words. Photographs of a new skill or technology are likely to persuade the interest more effectively than details of benefits that are read out by an extension agent.
