The roles of audio-visual aids in teaching and learning

Audio-visual aid is the best tool for making teaching effective and the best dissemination of knowledge. Audio–visual materials include tape recorder, radio, movie, projector method etc. If we use the audio-visual material for elementary education as curriculum, the objectives would be followings:

  • Augmented instruction: This is one of the important objectives of using audio visual material, using the application of slides and films in the classroom. Here teachers can use the audio visual aids to reinforce their teaching in the context of a lecture or activities based lesson. Thereafter, teachers can demonstrate any motivational movie according the needs of situation and relevant topic.
  • Independent learning: In the classroom, films, audio tapes and video tapes can be used instead of personal student teacher contacts. This forms of instruction can be used in continuing government schools where the teachers are not available adequate. Typically, informative and motivational films on selected topics and video tapes transmitted via various TV networks are typical of these types of material.
  • Self-assessment, evaluation and role playing: At the elementary school, the introduction of video tape recording equipment which does not require elaborates production facilitates stimulating the use of television for the self-assessment of children. Tape recorders can be replayed for the purpose of self-analysis by the children or peers analysis with their classmates. Therefore, “small group is an integral part of the Problem Based Learning approach, used consciously and conscientiously to achieve the learning outcomes”.
  • Enhance capacities for learning– It is argued that purposefully designed and successful small group learning facilitates learning through the development of audio-visual material that supports and promotes both cognitive and meta-cognitive development. Teachers may show some movie, cartoon and slow-motion animation for the use of teaching. Having finished, teacher can instruct children to sit in small group and tell what they saw. The ‘structures’ in small group can be applied as problem based learning, along with the tutorial process and the use of scenarios, help the students to learn how to learn in groups and learn how to anticipate, prevent, cope and deal with the difficulties that they will experience working in this way.

Manner of using audio and visual aids

Learning of children can be influences effectively by the audio-visual aid. Teachers can use television or projector method to explain the scientific phenomenon. It will take less time in describing the minute details of the things comparatively traditional method. Through television children can watch the big image of the object such as solar eclipse, use of water cycle , vermi composting, vermiculture , stories , drama, and composting in elementary education text book etc..

Audio visual will very useful and meaningful for those students belonging to literature background. All the genre of literature (novel, drama, tragedy, comedy etc.) can be shown easily through this device. Students will learn to understand it very soon without reading. Reading may seem little boredom but audio visual aid will maintain and hold the interest of students. The impact of television would be hundred times more than book.

Nature of learning

Audio visual aid will serve effective method in disseminative knowledge even in overcrowded classroom. Without this technical device, poorly teacher prepared cannot hold the class properly. If teachers use the help of audio visual in class such as projector, which would definitely stimulate imagination and catch the attention of students. Teachers often give instruction heavily loaded abstract verbalisms which seem meaningless sometime. So in case, teaching should be in simple and lucid manner. Hence, use of audio visual aid in classroom, will lead towards learning with understanding, learning by watching and learning as fun not as burden. Teachers should know which things of it are relevant and which are irrelevant, specially which how audio visual aid may contribute to an understanding of the lesson being taught.

 Benefits of audio-vsual aid

Teacher may demonstrate in many types of slide and movie in the classroom. It will enrich their understanding and vocabulary about the uses of language. Through recording, radio and tape, teacher can tell telecast many interesting and informative news, history and story. These will build a creative environment in elementary class children. Apart from that “an understanding of the arts-painting, sculpture, the dance, handcrafts-can readily be taught by means of television. And both radio and television are valuable media for teaching musical forms”.

Audio is a very effective medium of communication, which catch the heart and mind of people. Specially, it is useful for blind children, who can identify and recognise the various things surrounding them by listening different calls of animals, or sounds like rainfall etc.

Limitations of audio-visual aids

Using of audio visual aids decreases teacher’s autonomy in the classroom. For effective functioning of the audio-visual aids the trained experts are required which is not possible all the time.

Conclusion

In this way, we understood that audio-visual aid is the best tool for making teaching effective and the best dissemination of knowledge. Audio –visual material can be included tape recorder, radio, movie, projector method etc. Not to say that it has also some limitation that all schools cannot afford this modern technological devices because it is difficult to adopt this approach in government schools where still no adequate teachers, funding and proper infrastructure of classroom and water, toilet facilities. If this audio visual material is provided to govt. school, it will be a only show piece because teachers are also not very acquainted with it. Audio-visual material can be afforded by elite schools and also its use can be realized truly.
