The document discusses how people learn and remember information differently depending on their senses. We remember the most - 83% - through sight. Audio-visual aids can help learning by making abstract concepts more concrete and memorable. They motivate learners and make the learning process more interesting and effective. When using aids, teachers should select ones appropriate for the age and experience of the students, and choose aids that are realistic. Audio-visual aids are classified into projected, non-projected, and activity aids. Effective use of aids involves planning, preparation, proper presentation, and evaluation.

1. There is an old saying "What I hear I forgot,
What I see I remember, What I do I understand”
Research finding understands that generally we
learn one person through 1% by taste, 1.5 % by
touch,3.5% by smell,11% by hearing and 83%
through sight. We remember 20% of what we
hear,30% of what we see,50% of what we see
and hear,80% of what we say,90% of what we
say and do..

2. Audio-Visual Aids :
•Help to learn more and remember for long
•Give reality and vividness to learning
situations
•Motivate the learners
•Reduce verbalism
•Make the abstract concrete
•Make learning interesting, meaningful and
permanent
•Develop deeper understanding

3. •Using Visual Aids should not be considered as a substitution for teaching. It
only meant to supplement oral and written presentation.
•Use of aids in the class room should not be confused with providing
entertainment. The aim of using aids should be to make learning more
interesting and effective.
•Aids must be suited to the age and intellectual level of the pupil and to the
nature and extent of their previous experiences
•Aids should be realistic in nature. The use of actual specimen should be
preferred to showing a photograph or slide
•When a teacher has to select one aid from among a possible set ,economy of
time, effort and money and the efficiency of the aid should be the criteria for
making the selection
