Education is an integral part of society. Everyone must get an education and teaching students is not an easy profession and even to get the knowledge is not easy as it sounds. So, teaching aids are necessary today. It promotes students to learn and engages them in learning in various engaging ways. The meaning of teaching aids is a tool that helps to understand both are them. In today’s world, there are many different audio-visual aids available. From early childhood education to the adult learning environment, these tools have become a necessity in classrooms. These tools have helped students learn and retain more information, as well as make it easier for them to focus their attention. Communication has evolved with the growing use of audiovisual technology. And we can also apply these innovations in the classroom environment to improve communication between students and teachers. As stated by Postman in the article the classroom is a place for social interaction. One key to using audiovisual technology effectively is to use it as a teaching tool. For example, teachers can use video to illustrate concepts and audio for verbal explanations or presentations. Teachers can also use an interactive whiteboard that displays images from around the world. With a better understanding of audiovisual technology, teachers can learn how different equipment can play various interactive roles in the classroom, which will enable them to interact more easily with their students.
During my school times, We usually go to computer classes once or twice a week and too just learn computer lessons within a class only blackboards were used for visual learning purposes, and textbooks were to be considered the sole learning tool. However, when I started teaching I realized that an audio-visual aid will serve as an effective method of disseminative knowledge even in an 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 a projector, which would definitely stimulate imagination and catch the attention of students. Teachers often give instruction heavily loaded abstract verbalisms which seem meaningless sometimes. So in case, teaching should be in a simple and lucid manner. Hence, the use of audiovisual aid in the classroom will lead towards learning with understanding, learning by watching and learning as fun, not as a burden. Teachers should know which things of it are relevant and which are irrelevant, especially how audiovisual aid may contribute to an understanding of the lesson being taught.
In this way, we understood that audio-visual aid is the best tool for making teaching effective and the best dissemination of knowledge. Audiovisual material can be included tape recorder, radio, movie, projector method, etc. Not to say that it has also some limitations that all schools cannot afford this modern technological device because it is difficult to adopt this approach in government schools where still no adequate teachers, funding, and proper infrastructure of classrooms and water, and toilet facilities. If this audio-visual material is provided to govt. school, it will be an only showpiece 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.
