Making Your Classroom Interactive – Audio Visual
AV FTG is the electronic media containing both a visual and a sound component, for instance, slide-tape, films, video tapes, computer video, corporate events, and live theatrical productions. The term ‘audio visual’ could also be applied to a wider range of mediums, including television commercials (as in ads for products), audio books (containing fictional audio stories), spoken word or other recorded audio, sung words, instrumental music, computer animation, computer graphics, and video animations. Audio visual is often confused with information systems or entertainment systems, but they are very different from one another and their scope is much wider. Audio visual consists of equipment that either complements or acts as a part of the information system, for instance, an audio-visual system might include audio-visual equipment such as DVD players, VCR/DVD recorders, game consoles, televisions, personal computers, DVD/VCR writers, recorders, and headphones. It also often involves the use of a form of electronic communication such as e-mail or audio and voice conferences.
Audio visual is a form of visual communication, in which the content or information presented either way involves some type of movement. Audio-visual presentations could include audio and or visual aid(s) such as text translation, interpretation, audios or subtitles, interactivity, and kinesthetic representation. Kinesthetic representation refers to the emotional response one experiences when viewing a text or seeing a moving picture.
This medium is usually used for training purposes in schools and colleges, or in corporate or business settings for presenting short courses or seminars to audiences. Audio visual aids can be non-interactive, or they can incorporate interactive features such as questions and discussions, that require participants to engage physically and mentally with the material. The effectiveness of audio visual aids depends on how well the content is presented, and on the understanding of the users regarding the cues used to guide the presentation, and the implications that follow from these cues. For example, if you are teaching a group of school children how to spell, you will probably need a book and a pen and paper, a long spoon to put the spell checker down, and perhaps some clear instructions about the various parts of the word. You do not want to have your class members fumble with their pens and paper, so audio visual aids can help your students to learn faster.
