GRAPHIC AIDS
Graphic
aids are charts, diagrams, graphs, maps, flashcards, posters, pictures,
photographs, leaflets, folders, pamphlets, cartoons and comics. They are
two-dimensional materials having no depth which communicate facts, ideas and
relationships clearly through words, lines, drawings, symbols and pictures.
Graphic aids can serve many educational objectives for group teaching of 20 to
30 students. They help to:
1.
Visualise abstract concepts which are difficult
to understand - concepts of size, rate of growth, inner structure of an object
or machine etc.
2.
Reduce the amount of verbal talking and help in
giving clear explanations; visuals in charts, graphs, diagrams and posters, cut
down words.
3.
Present the information in a specific and
systematic manner. Since majority of them are formal aids, they have to be very
systematic and organised.
They are also popular
because they are
1.
Comparatively less expensive.
2.
Easy to make as no technical skills are
required. Regular teachers, with some knowledge of drawing and who desire to be
creative can prepare them.
3.
Easy to use. Very special arrangements and
machines are not required.
4.
Easily usable and reusable as they are flat,
two-dimensional materials.
Graphic Aids - I
This section includes those graphic aids which have similar principles
of preparation, presentation and storage, and can be employed to do serious
classroom teaching in home science.
Graphic Aids - II
This
section includes those graphic aids which primarily may not be used for serious
classroom teaching, and have individual, specific principles of preparation and
presentation. Nevertheless, their knowledge may aid a home science teacher in
doing her job efficiently.
POSTERS
A poster is a bold illustration with little or no writing. A good poster conveys the message at a glance. It is not used
for serious classroom teaching as its main purpose is to publicise an event - demonstration, lecture,
exhibition etc. or a product -
embroidered garments, children's clothes, knitted articles etc. or an idea - save money, give up smoking,
preserve water, keep clean, abolish dowry, conserve energy, etc.
While preparing a poster
1.
Have only one idea suggesting an action.
2. Use a thick chart or drawing paper, which is usually available in 22 x
28 inch size, keeping to 1 inch margin on all sides.
3.
Have an informal but balanced layout.
4.
Use large, bold and simple illustrations for a
passerby to get the message easily. Avoid details and shading.
5. Have brief, personal, forceful and appealing titles. For example eat
vegetables, - be healthy - health is important, etc.
6.
Use simple, large, bold, horizontal lettering.
7.
Plan definite eye movement.
8.
Use colour to make the poster attractive. A dark
colour background with white or light colour lettering, and an illustration
make a very appealing and unique poster. Use a few, well matched colours to
have a pleasant picture, and bright colour in small proportion to attract
attention.
Place a
poster at a high level, in a place which is free from other advertisements, and
from where many persons pass by; examples - cafeteria, library, common room,
etc.
