WHAT TEACHING AIDS CAN DO?
1. Provide greater sensory experiences to help the students develop understanding and retain knowledge for a longer time through five senses - vision, hearing, touch, smell and taste,
2. Provide a variety of learning materials and experiences; using chart, films-strip, model, puppet, tape etc.,
3. Increase interest and involvement of students' in learning; instead of plain lectures. Lectures with teaching aids can hold attention and interest of students,
4. Supply a concrete base for conceptual thinking; developing a concept of colour harmony through a colour wheel, Aid a teacher in giving clear explanations; explaining process of reproduction with the help of charts and models,
5. Provide experiences which are not easily available to make learning wide and deep; video tapes on life of people in other countries.
6. Help to increase meaningful vocabulary; learning correct names of Indian embroidery with the help of samples of embroidery,
7. Develop continuity of thought; need for good health need for population education,
8. Introduce self-activity; making posters, reading maps; making flowers from waste materials,
9. Aid in mass communication; using films, television, radio broadcasts, leaflets, folders, pamphlets.
However, remember that the teaching aids cannot do one thing, that is replace 'a teacher'. They are in general, to 'aid' the teacher in enriching the learning experiences to communicate better. A teacher cannot entrust her class to a teaching aid and leave the room to attend to some other work.
