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. Audiovisual 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 audiovisual 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.
