2. Introduction
Each extension method has its own advantages and disadvantages
One cannot therefore talk about the best extension method
Each method plays a part in an extension programme
Different extension methods can be combined in a purposive manner e.g. a lecture can be supported with audio-visual aids
A multi-media approach can be used for the needed effectiveness of an extension programme

3. Audio-visual Aids
Audio-visual aids tend to support talks and group discussions (group ext method)
Audio-visual aids include blackboards, flipcharts, overhead and video projectors, photographs, drawings, graphs, maps, slides, filmstrips, film, radio, television, sound and videotapes, and CD-ROMs (Compact Disc Read-Only Memory)
CD-ROMs, for instance, can carry large quantities of print images as in books and encyclopedias as well as colourful illustrations

4. Benefits of Audio-visual Aids
Audio-visual aids can increase effectiveness of extension
Audience is likely to remember more from a talk illustrated with audio-visual aids than from a speaker who uses no aids
Audio-visual aids capture audience attention
They can highlight the main points of the talk clearly
The possibility of misinterpreting concepts is reduced
People remember messages perceived with several senses better than those perceived with a single sense
Some aids help us to structure our messages in a systematic way
Software such as Microsoft Powerpoint in conjunction with a personal computer permits rapid and easy preparation of materials for projection through video screens or projectors

5. Audio-visual media can serve two different functions:
Improve the process of information transfer (mainly a cognitive process)
Develop or strengthen the motivation to change (an emotional process). Films and video can be useful here, because they arouse emotional involvement. Drama groups can also serve the purpose

6. Effective Use of Audio-visual Aids
For effective information transfer, the structure of the message must be carefully thought out
It is important to coordinate the audio or sound channel with the visual channel to ensure that the reaction of one synchronizes with the other
The audio signals must not conflict with the visual so that the receiver will not be confused
Planning for the use of audio-visual must be directed towards uniting word and image. Thus, when discussing a film you should first outline its key points, show it, then hold group discussion
Other audio-visual aids such as play or puppet show can be developed to suit the interests of specific groups or audiences

7. Effective Use of Audio-visual Aids (cont’d)
Simple media such as blackboard and flipcharts present problems with equipment maintenance, whereas films, videocassettes, and computers require relatively costly projection equipment and a reliable source of electric power
In evaluating the use of these methods, ext agents can use simple pre-tests to check whether farmers understand one type of presentation more easily than another
Points not clearly understood can be clarified when redesigning the presentation

8.  Use of Folk Media
Interest in folk media as extension method is gaining prominence
Such folk media include theatre play, songs, puppet shows, story tellers and other indigenous/traditional forms of entertainment
Interest in folk media has increased because the mass media have been less successful in promoting rural development
Again, there has been decreased emphasis on “top down” communication with rural people in favour of participatory approaches (folk media usually involve participation

9. Advantages of Folk Media
Folk media often appeal to the emotions of audience members, identify themselves with players
They fit closely with local cultural patterns, whereas the mass media bring information from urban centres and from foreign countries
They are often more effective at arousing the motivation to change
The audience tend to have confidence in the message because communication takes place in a form they are accustomed to, in their dialect and from people they often know
Village people may participate in these folk media by writing scripts for plays, composing songs or assisting in the production

10. Effective Use of Folk Media
Folk media, as a traditional extension method, may fail unless they are used by people who understand the local culture
Folk and modern media do not have to compete, but may complement each other. Folk media can be shown on television and folk songs with development theme can be broadcast on radio

11. Use of Modern ICT Tools
The emergence and development of modern ICT tools has facilitated the dissemination of extension messages to clients
Improvement in telecommunication, information technology and media broadcasting technologies offers farmers new opportunities to obtain information efficiently and effectively
Farmers can now access reports of research findings, production and market information on the Internet
The use of the mobile phone has facilitated farmer-to-farmer, farmer-extension agent and farmer-input supplier extension
