Organization of an audio-visual programme.

2. organization of an audio –visual
programme
• The following general procedure may be adopted in
organizing an audio –visual programme.
• Planning
• Identify the objective and audience.
• Plan for a simple, practical, educational and
interesting presentation.

3. PREPARATION
• Collect relevant equipments and materials.
• Pre-view the audio-visual aids.
• Rehearse and adequate preparation.
• Check power supply, lighting, need for total
darkness, seating arrangements etc.
• Select and train the audio-visual operator or any
other suitable person in the organization.
• Arrange the audio-visual aids in a sequence and
have them within easy reach.

4. PRESENTATION :
• Motivate the audience and stress on the key points.
• Present aids at the right moment and in proper
sequence.
• Take precaution against wrong presentation.
• Stand on one side of the material presented and
speak facing the audience.
• Avoid a hurried presentation.

5. FOLLOW-UP:
• Observe reaction of the audience.
• Clarify doubts and dispel misunderstanding, if any.
• Improve subsequent presentations by deleting
irrelevant and old materials and adding something new,
if required.
LIMITATIONS:
• Because of cultural difference, the audience may form a
mistaken or distorted impression about the audio-visual
aids.
• Teaching may be scratchy instead of being complete.

6. • Over-reliance on audio-visual aids may convert
teaching to showmanship.
• For fool-proof and effective presentation, pre-testing
and/or pre-view of audio-visual aids is a-must.
• Proper strong and maintenance of audio-visual aids
are important.
• To facilitate running of audio-visual aids on
electricity, a stand by portable generator, a multiple
switch-board with a long flexible cord for-back
screen and a folding table may be kept ready at
hand.

7. CRITERIA FOR SELECTION AND EVALUTION OF AUDIO-
VISUAL AIDS:
• Selection and evaluation of audio-visual aids may be
made on the basis of some items suggested below .
• The scoring procedure is given on the right hand
side.

9. • This is an illustration and the investigator may add
or delete some items. For the format given here.
The range of scorers is from 0 to 21.
AUDIO AIDS:
• TAPE RECORDER:
• Is an equipment for recording sound on magnetic
tape by electromagnetic process. which may be
played back when needed.
• The tape may be of celluloid, plastic or high
tensile polyester film.

10. • These have an ultra thin coating of iron oxide on one
side. the tape is magnetized as it passes through a
recording head.
• To play back the tape is passed again through the
magnetic head.
. The recording and play back processes are
accomplished by the same head.
• The tape recorder is suitable for use in meeting,
training programme, campaign, recording radio
programme etc.

11. ADVANTAGES :
• 1. Facilitates on the spot recording of sound.
• 2. Helps in duplication and dissemination of sound.
• 3. The recorded tape can be immediately played back
without any processing.
• 4. Facilitates editing of sound by adding, deleting and
adjusting tapes back and forth.
• 5. Helps in synchronization of sound with picture.
• 6. Preservation of recorded sound in tapes for future
use.
• 7. Easy to operate
• 8. Low operation cost, as the same tape may be used
over and over again.

12. • A recorder for extension work should have the
following features.
• Simple with minimum number of buttons and
knobs.
• Light weight and easy to carry.
• Battery operated, but can also be used on AC/DC
power supply.
• Variable speed with 1to2 recording tracks Sturdy in
construction and moderate in cost

13. 2. PUBLIC ADDRESS SYSTEM
• Public address system is a set of equiepments to
amplify sound so that it is audible to a large audience
over a distance.
• It is useful for extension programmes involving a large
number of people such as mass meeting, training
programme, field day or farmer’s day campaign,
exhibition etc.
• The public address system has three components
microphone, amplifier and loudspeaker. The
microphone is connected to the input terminal of the
amplifier and the loudspeaker to the output terminal.

14. • It may be run on dry/wet battery, or ac/dc power
supply. Test the microphone before use.
• Place it at distance of about 25cm.From the person or
instrument producing the sound.
• The distance should be maintained to get a good clear
sound.
