Audio visual aids are instructional devices that allow a message to be both heard and seen simultaneously, such as television, video films, and documentary films. They are supplementary teaching devices that assist the teacher in the learning process by helping to convey meaning clearly, capture attention, highlight main points, and allow students to remember information longer. Audio visual aids can be classified according to the senses involved (audio, visual, or both), the method of projection (direct, indirect, or reflected), or the generation of technology used (handmade, printed, photographs/film, or computer-based). Projected aids are those that use equipment like slide or film projectors to magnify an image on a screen.
