Fisheries Extension Education (2+1)

Factors to be Considered in Selection of Audio Visual Aids

1. The teaching objective must cover the type of behaviour change, gaining information, changing attitudes or learning some skill.
2. The nature of the subject matter being taught.
3. The nature of audience – age, education, interest, experience, knowledge of subject, intelligent level of the group, etc.
4. The size of the audience – for instance flash cards can be used for small group only, motion pictures for large audience.
5. Aids must be easy to handle and transport. And it should be clean attractive and clean.
6. Relative cost of various aids. Effective aids need not necessarily be costly.
7. An extension worker makes use of indigenous material, when the teaching aid is not available for the presentation.
