Comprehensibility:In selecting and using visual aids we must try to choose those things as aids which relate the new experience with past experience and which are within the comprehension of the students who are to use it.
For instance; lee’s take-a teacher finds that his class is experiencing substantial problem in locating and understanding the connection between the parts of a circulatory system. And the instructor then draws purely a diagrammatic draft on the blackboard very clearly. This clarified the difficulties and issues because it is simple and readily comprehended by the students.
Motivation:How to motivate students for learning language? Audio visual aids motivate and act as a catalyst for learners as they make the learning process in the classroom interesting especially in activity-oriented subjects for effective learning.
Realism:A visual aid must necessarily possess the quality and niche of developing real concepts of different areas of life. Instead, we may try to develop in our students the concept very similar to that of the movement of electrons in the atom. We the teachers, in this case, try our best to describe accurately with the help of diagrams and charts but the students are shown the actual film of the movements of electrons; an entirely very different, but effective concept will emerge. Nearly all the visual aids are lacking one or the other characteristics but the actual specimen clarifies the concept due to realism, as the learners experience the fact in a practical approach of learning and understanding.

Advantages of Audio-Visual Aids:

To Challenge the Attention of the Pupils: The teacher who uses devices can usually see that the attention of the whole classroom is on the lesson and that should not be distracted. This is generally true when teachers are dealing with the lower classes. Devices should never be used by the teacher as mere attractions or entertainment. Exposure to visual or audio-visual material and nothing more is not an educative procedure.
