Audio-visual aid is the best tool for making teaching effective and the best dissemination of knowledge. Here a student can develop his/her communication skills. Audio-visual tools allow musical and visual learners to learn information in a way that stimulates their intelligence style. Students are introduced to the concept of conveying information creatively – which comes in handy when they must give presentations in class or later in their careers. Exposure to audio-visual aids in school teaches kids how to communicate through sight and sound, and to tie the things they see and hear together to understand an important message.
