Audio-Visual Media: Concept, Importance and Various Forms - Use of AV aids: Types,

Advantages and Problems involved.

Audio visual aids are important in education system. Audio visual aids are those devices which

are used in classrooms to encourage teaching learning process and make it easier and interesting.

Audio visual aids are the best tool for making teaching effective and the best dissemination of

knowledge.

According to Kothari commission. “The supply of teaching aids to every school is essential for

the improvement of the quality of teaching. It would in deed doing about an educational

revolution in the country

The National Policy on Education, 1986 and as modified in 1992 has laid a great stress on the use

of teaching aids, especially improvised aids, to make teaching-learning more effective and

realistic.

Meaning of Audio-visual aids Audio-visual aids are instructional devices which are used to

communicate messages more effectively through sound and visuals. Audio-visual aids help in

stimulating the sensory organs like ears and eyes and facilitate quick comprehension of the

message by the audience. These may be used for literate as well as illiterate people.

Audio-visual aids are used to improve teaching, i.e. to increase the correctness, clarity, and

effectiveness of the ideas and skills being transferred. They enable the learner to LOOK, LISTEN,

AND LEARN ; to learn faster, to learn more, to learn thoroughly and to remember longer. The

audio-visual aids help in completing the triangular process of learning, motivation, clarification

and stimulation.

According to Crow & Crow – “ Audio-visual aids gives learners the opportunity to benefit from

vicarious experiences with people events, objects, ad cause and effect relationship.”

Types of Audio-visual Teaching Aids Audio-visual teaching aids can be divided into three

categories.

 Audio-teaching aids – The teaching aids where ears are used. Examples are Tape-

recorder, Radio, Gramophone, Audio record player.

 Visual-teaching aids – The teaching aids where eyes are used. Examples are Chart, Black

and white board, Maps, Pictures, Models, Text books, Slide projector, Transparency, Flash

cards, print materials etc.

 Audio-visual teaching aids – The teaching aids in which both eyes and ears are used

together. Examples are LCD project, Film projector, TV, Computer, VCD player, Virtual

classroom, Multimedia etc.

Need of Audio-visual aids Every individual has the tendency to forget. Proper use of teaching aids

helps to retain more concepts permanently.

 Students can learn better when they are motivated properly through different teaching aids.

 Teaching aids develop the proper image when the students see, hear, taste and smell

properly.

 Teaching aid provide complete example for conceptual thinking

 Teaching aid provide direct experience to the students.

 Teaching aids make learning permanent.

 Teaching aids create environment of interest for theØ students.

Importance of Audio-visual aids Audio-visual aids are aids used in the teaching-learning process

have wide significance from the view points of teachers as well as learners.

The importance of audio-visual aids are

 Use of maximum senses – Senses are said to be gateway of· knowledge. Audio-visual aids

call for the utilization of as many senses as possible and thereby facilitate the acquisition

of maximum learning on the part of the students.

 Based on maxims of teaching – The use of audio-visual aids· provide assistance to the

teacher for following maxims of teaching like ‘simple to complex’, ‘concrete to abstract’

‘and ‘known to unknown’ and ‘learning by doing’, etc.

 Helpful in the process of attention – Attention is the key· factor in any process of

teaching-learning.

 Audio-visual aids help the teacher in creating proper situations and environment for

capturing as well as maintaining the interest and attention of the students in the class room

activities.

 Save time, money and energy – Time and energy of both· teachers and students may be

saved due to audio. The abstract concepts may be easily clarified, understood through

their use.

 Meet the individual differences requirements – There are· wide individual differences

among learners. The use of various types of Audio-visual aids helps in meeting the

requirements of different types of pupils.

 Solve the problem of indiscipline – With the introduction· of Audio-visual aids, there is

less room for the creation of a passive , dull, and uninteresting environment in the class

room.

 Help in the development of scientific attitude –· Use of Audio-visual aids helps in

cultivating scientific attitude among students.

 A good motivating force – Audio-visual aids match the inner· urges, instincts, basic

drives, and motives of the student and thus prove a potent motivating force for energizing

learners to“ learn effectively”.

 Clarity of subject matters – Audio-visual aids bring clarity to· the various difficult,

abstract concepts related to subjects.

Objectives of Audio-visual Aids

 To make teaching-learning process effective.·

 To make the students more active.·

 To develop interest towards learning.·

 To make the teaching, clear, easy and understandable
