Illustration—
Illustration is a device that
stands for the use of means and materials in order to help students to acquire
concrete knowledge of the materials presented by making it clear, interesting,
intelligible and comprehensible. Illustrations are divided into two categories:
—
1.
Verbal and 2. Concrete

word, pictures, examples, metaphors, analogies, etc. then he makes use of
verbal illustrations. But when he/she uses objects, models, charts, maps,
diagrams, etc., he/she makes use of concrete illustrations.

a.
To make abstract ideas concrete.
b.
To introduce nobility and variety in the
class.
c.
To make an appeal to the senses and the
imagination of the student.
d.

precise.
