audiovisual education or multimedia-based education ( MBE ) is an instruction in which particular attention is given to audio and visual presentation of material in order to improve understanding and retention.

Following the use of training films and other visual aids during World War II, audiovisual technology gradually developed in sophistication and use into a wider range of educational institutions such as schools, colleges, universities, museums and galleries, as well as in tourist destinations.

Children learn best by observing and imitating adult behavior. It is therefore evident that learning is more effective when sensory experiences are stimulated. These include images, slides, radios, videos, and other audiovisual tools. According to Webster's dictionary, audio-visual aids are defined as "training or educational materials directed at the senses of hearing and the senses of sight, film, recording, photographs, etc. Used in classroom instruction, library collections, or the like.". The concept of audiovisual aids is not new and can be traced back to the seventeenth century when John Amos Comenius (1592-1670), a Bohemian educator, introduced the image as a teaching aid in his Orbis Sensualium Pictus ("Sensual World image") illustrated by 150 pictures of everyday life. Similarly, Jean Rousseau (1712-1778) and JH Pestalozzi (1746-1827) advocated the use of visual material and play in teaching. Recently, audiovisual aids were also used extensively during and after World War II by the armed services. The successful use of images and other visual aids in the US armed forces during World War II proved the effectiveness of instructional tools. There are different types of audiovisual materials ranging from filmstrips, microforms, slides, projected opaque materials, tape recordings and flashcards. In today's digital world, audiovisual aids have grown exponentially with some multimedia such as educational DVDs, PowerPoint, educational television series, YouTube, and other online materials. The purpose of audio-visual assistance is to improve teachers' ability to present lessons in a simple, effective and easy to understand way for students. Audiovisual materials make learning more permanent because students use more than one sense. It is important to create awareness for federal states and ministries of education as policymakers in secondary schools from the need to instill audiovisual resources as the main pedagogical teaching in the curriculum. The result is to promote audiovisual material in high school because they do not have the resources to produce it. Visual instruction makes abstract ideas more concrete for learners. This is to provide a basis for schools to understand the important role in encouraging and supporting the use of audiovisual resources. In addition, studies have shown that there is a significant difference between the use and not using audiovisual material in teaching and learning.

Advantages

In this modern world we use digital tools to improve teaching and learning process. The most common tool we use in today's class is the PowerPoint slides, which make the class more engaging, dynamic and effective. It also helps introduce new topics in an easy way. The use of audiovisual aids allows students to remember concepts for longer periods of time. They convey the same meaning with words but give clear concepts that help bring effectiveness in learning.

Integrating technology into the classroom helps students experience things virtually or representative. For example, if the teacher wants to teach a lesson about the Taj Mahal, perhaps not all students in India have visited the venue but you can show it through the video to allow students to view the monument with their own eyes. Although first-hand experience is the best way to educate experience but such experiences are not always practical so in some cases we need to have substitutions.

The use of audio-visual aids helps in maintaining discipline in the classroom because all students' attention is focused on learning. This interactive session also develops critical thinking and reasoning which is an essential component of the teaching and learning process.

Audiovisuals provide opportunities for effective communication between teachers and students in learning. For example, in English as a Foreign Language (EFL) lesson, the difficulties faced by EFL learners are lack of motivation, lack of exposure to the target language and lack of pronunciation by teachers, and such difficulties can be overcome by Audio as communication and visual purposes as more lots of exposure.

Students learn when they are motivated and curious about something. Traditional oral instructions can be tedious and painful for students. However, audio-visual use provides intrinsic motivation to students by peaking their curiosity and stimulating their interest in the subjects.

Disadvantages

One should have the idea that too much audio-visual material being used at a time can lead to boredom. This is only useful if implemented effectively. Considering that every teaching and learning situation varies, so it is important to know that all concepts can not be effectively learned through audiovisuals. Most of the time equipment such as projectors, speakers and headphones are rather expensive so some schools can not afford it. It takes a lot of time for teachers to prepare lessons for having an interactive class session. Also valuable time teachers can be lost in getting familiar with new equipment. Some students may feel reluctant to ask when a movie is playing and in a small room can be a physical barrier. In places where electricity is not available in rural areas, it is impossible to use audio-visual aids that require electricity.

Conclusion

It is clear that audio visual aids are an essential tool for teaching and learning. It helps teachers to present lessons effectively and students learn and retain better concepts and for longer durations. The use of audio visual aids enhances students' critical and analytical thinking. It helps to remove the abstract concept through a visual presentation. However, improper and unplanned use of these tools can have a negative effect on learning outcomes. Therefore, teachers should be well trained through in-service training to maximize the benefits of using these tools. The curriculum should be designed in such a way that there is an option for activity-based learning through audio-visual aids. In addition, the government must fund resources to purchase audio-visual aids at schools.
