What is Audio Visual Media

Navigasi - Audio-visual media is one of the media that can be used for learning activities, even though there are differences of opinion from experts regarding the meaning, advantages and disadvantages and benefits.

Understanding Audio Visual Media, Strengths and Weaknesses and Benefits are described by experts at length. Understanding Audio Visual Media According to Marshall Meluhan (2008: 99) is a form of audio-visual intermediary used by humans to convey or spread ideas, ideas, or opinions so that the ideas, opinions or ideas put forward reach the intended recipient.

Audio-visual learning media can also mean teaching media and educational media that activate the eyes and ears of students during the teaching and learning process. Audio-visual media is a type of media that in addition to containing sound elements also contains elements of images that can be seen, such as video recordings, various sizes of films, sound slides, and so on. The ability of this media is considered better and more interesting, because it contains both elements of the first and second types of media.

In the teaching and learning process, the presence of the media has a fairly important meaning. Because in these activities the unclear material to be delivered can be helped by presenting the media as an intermediary.

One of the technologies in the teaching process is choosing learning media. According to Rossi and Breidle, learning media are all tools and materials that can be used for educational purposes, such as radio, television, books, newspapers, magazines, and so on. This learning media will help make it easier for students to digest the knowledge information conveyed. Learning media according to the characteristics of sensory stimulation can be in the form of Audio (sound), Visual (image), and Audio Visual.

According to Basyirudin Usman (2001:99), classifying the main characteristics of media on three main elements, namely sound, visual, and motion. The visual form itself is further divided into three forms, namely visual images, lines (linear graphics) and symbols. As in general, audio-visual media has a fairly high level of effectiveness, according to research, the average is above 60% to 80%.

Teaching through audio-visual is clearly characterized by the use of hardware during the learning process, such as film projectors, televisions, tape recorders and wide visual projectors. So teaching through audio-visual is the use of material that is absorbed through sight and hearing and does not entirely depend on understanding similar words and symbols. This type of audio-visual media has better capabilities because it includes the first and second types of media. This medium is divided into two:

Silent audio-visual: media that displays sound and still images such as sound slides, soundtrack films, sound prints.

Audio-visual motion: media that can display elements of sound and moving images such as sound films and video-cassettes.

Advantages of Audio Visual Media

  1. Teaching materials will be clearer in meaning so that they can be better understood by students, and allow students to master teaching objectives better.
  2. Teaching will be more varied, not merely verbal communication through the utterance of words by the teacher. So that students do not get bored and the teacher does not run out of energy, especially when the teacher teaches for every hour of the lesson.
  3. Students do more learning activities, because they do not only listen to the teacher's description, but also observe, perform, demonstrate, and so on.
  4. Teaching will attract more students' attention so that it can foster learning motivation.

Weaknesses of Audio Visual Media

  • Audio media, which uses more sound and verbal language, may only be understood by listeners who have a good level of mastery of words and language.
  • Presentation of material through audio media can lead to verbalism for listeners.
  • Less able to display the details of the object that is presented perfectly.

Functions of Audio Visual Learning Media

Learning media is an important part in the implementation of education in schools. Through learning media, teachers will find it easier to convey material and students will be more helpful and easier to learn.

Learning media are intermediaries that carry messages or information between sources and recipients. Learning media or learning materials generally consist of knowledge, skills and attitudes that must be learned by students in order to achieve predetermined competency standards (Depdiknas, 2006:4).

Learning media are arranged with the following objectives:

  1. Provide learning media in accordance with the demands of the curriculum by considering the needs of students, namely learning media that are in accordance with the characteristics and settings or social environment of students.
  2. Assist students in obtaining alternative teaching materials in addition to textbooks which are sometimes difficult to obtain.
  3. Make it easier for teachers to carry out learning.

According to Arief S. Sadiman, et al (2011: 84) stated that media voters include a) intending to demonstrate it as in lectures on media, b) feeling familiar with the media, for example a lecturer who is accustomed to using a transparency projector, c) want to give a more concrete picture or explanation, and d) feel that the media can do more than what can be done, for example to attract students' interest or passion for learning.

In line with the development of technology, the learning media also experienced development through the use of technology itself. According to Azhar Arsyad (2011: 71) in applying learning media, it should pay attention to the following criteria:

  • Ability to accommodate appropriate stimulus presentation (visual and/or audio)
  • Ability to accommodate appropriate student responses (written, audio, and/or physical activities)
  • Ability to accommodate feedback
  • Selection of primary and secondary media for presenting information or stimuli, and for exercises and tests (preferably exercises and tests using the same media)
  • Enjoyment level (institution, teacher and student preferences) and cost-effectiveness

According to Azhar Arsyad (2011: 15) the main function of learning media is as a teaching aid that also influences the climate, conditions, and learning environment that is organized and created by the teacher. Meanwhile, according to Hamalik (in Azhar Arsyad, 2011) that the use of learning media in the teaching and learning process can generate new desires and interests, generate motivation and stimulation of learning activities, and even bring psychological effects on students.

  1. According to Arif S. Sadiman, et al (2011) states that the uses of learning media are:
  2. Clarify the presentation of the message so that it is not too verbalistic.
  3. Overcome the limitations of space, time and senses.
  4. The use of appropriate and varied learning media can overcome the passive attitude of students.
  5. Provide the same learning stimulus.
  6. Equal experience.
  7. give rise to the same perception.

The principle of relevance means that relevant learning materials should be related to the achievement of competency standards and basic competencies. The principle of consistency means that there is a consistency between teaching materials and basic competencies that students must master. The principle of adequacy means that the material taught should be adequate in helping students master the basic competencies being taught. The material should not be too little, and not too much. If too little will be less helpful in achieving competency standards and basic competencies. On the other hand, if it is too much, it will waste time and unnecessary energy to learn it (Akhmad Sudrajat, 2008).
