The Merriam-Webster dictionary defines audio visual aids as “designed to aid in learning or teaching by making use of both hearing and sight.” The Dictionary.com definition is “training or educational materials directed at both the sense of hearing and the sense of sight; films, recordings, photographs, etc., used in classroom instruction, library collections, or the like.” The Instructional Technology course offered by ecoursesonline describes them as “instructional devices which are used to communicate messages more effectively through sound and visuals.” From the definitions, we can surmise that audio visual aids are devices or materials that tap into both the hearing (or auditory) sense and sight (or visual) sense. Their purpose is to provide instruction, education or communication. Audio visual aids may take the form of a: Powerpoint presentation in support of a verbal lecture Video clip with voice over, and moving or still images Interactive whiteboard Television Projected images in support of verbal dialogue A graphic, chart or written material in support of verbal dialogue Furthermore, a study on Visual, Audio, and Kinesthetic Effects on Memory Retention and Recall by Udomon, Xiong, Berns, Best, and Vike (2013) revealed that retention and recall of information is significantly improved when two or more senses are engaged in learning the information. Information presented in both audio and visual formats is more likely to be retained than information presented either way alone. Interestingly, you can further improve retention by encouraging note-taking while listening to and viewing the audio visual information. The act of writing taps into the kinesthetic style of learning.

15. PRODUCTION OF AUDIO
VISUAL AIDS
Production Of Av/Training Materials
Broadly speaking, there are two types of production:
(i) Commercially produced
(ii) Locally produced materials/aids
• Commercially produced materials are designed for a
relatively heterogeneous audience and they The
locally produced materials are designed for more
specific purposes and for relativelycould be useful for
multiple purposes.
• homogenous learner For adequate use of training
aids in extension work, it is imperative to encourage
extension agents to acquire and develop skills in the
design and production of simple learning aids.

16. GENERAL GUIDELINES FOR THE PRODUCTION OF
TRAINING MATERIALS/AIDS
• (1) Identification or understanding of the specific training
objective.
• (2) Familiarity with the characteristics of the target audience to
ensure suitability in terms of age, social and cultural background,
beliefs, linguistic competence etc.
• (3) The content of the message should then be selected based
on the first 2 guidelines.
• (4) Cost effectiveness must be ensured.

17. FACILITIES NEEDED FOR
PRODUCTION
•1. Spacious room for planning, design and
development.
•2. Provision for graphics, photographic and
audio materials
•3. Storage space for quick and easy and
retrieval of materials
•4. The maintenance culture to ensure
continuous usefulness of the facility.

18. MATERIALS FOR PRODUCTION
• Adequate materials should be provided for graphics,
sound recording, photography, duplicating and
reproducing materials and some printing material.
• e.g. graphics require ampie supply of card boards,
newsprints, brown papers mechanical lettering
devices cut out letters, pens, inks, pencilsmarkers,
rulers, water colour transparency sheet, laminating
materials etc. For photography, we need ample
supply of films and printing materials.

19. EQUIPMENT FOR PRODUCTION
•Equipment should be provided for typing
and production of materials.
•Tape recorders, editing equipment, tape
duplicator for audio aids.
•Video camera and still camera.

20. CONCLUSION:
• The modernising world needs a modren thoughts
and technology audio visual aids are one of those to
teach many and to give knowledge for big size of
people
• There are many advantages and disadvantages too
for this type of modernization but we should use
them in a fair way
