In narration, the teacher may go astray. There is a possibility that he will speak irrelevantly and that he will waste a lot of valuable time. It is prescribed for memory and comprehension.
There should be the art of excellent communication involved. The teacher must have thorough knowledge or imagination about the item and event to be narrated to project the proper picture before the learners.
The teacher must be confident and patient during narration. Names of objects, and places, should be written on the blackboard in order to facilitate recall. The pace of narration should be taken care of. It should neither be too fast nor too slow.
Here, the teacher has to elucidate, explain, or present facts and phenomena using certain aids in verbal form.
Illustration is divided into two categories: verbal and concrete.
When a teacher applies the use of words and pictures, puts examples of comparisons, studies analogies, uses metaphor, and explains the meaning of a thing, object or phenomenon by giving equivalent terms for associating with previous knowledge of students, he is said to employ verbal illustration.
When a teacher makes use of concrete material like real objects, specimens, models, charts, pictures, graphs, maps, and diagrams by making a direct appeal to the senses of the students, he is said to make use of concrete illustration.
USE AND IMPORTANCE
The Illustrations make abstract ideas concrete and thus make teaching and learning meaningful and interesting.
In terms of catching devices and motivation agents, they are most effective.
The mental picture of the presented material becomes clear, definable, precise, and graspable with the help of appropriate illustrations.
The use of illustration as a teaching method proves quite useful and effective in the teaching of almost all the subjects of the school curriculum.
In language, teachers may use metaphors, incidents, stories, equivalent words, popular sayings, and idioms as verbal illustrations. He may also use pictures, charts, models, and maps to make language classes more interesting.
Geographic facts, ideas, concepts, and principles can never be properly taught without the use of maps, models, globes, and pictures.
DEFECTS AND LIMITATIONS
Overloading the lesson with illustrations, may adversely affect the teaching-learning process.
As a result, children may lose interest and lose their curiosity.
In the absence of a judicious selection of illustrations, they may not produce any positive results.
The use of illustrations requires a lot of time, energy, and resources-both human and physical-in an educational setting.
Moreover, in a crowded environment of classes in our country, we cannot expect the teacher to cover the entire syllabus with the help of illustrations in a limited time.
The teacher should properly plan the use of illustrations in his lesson.
The teacher must carefully locate where verbal and concrete illustrations should be used.
Learners must be able to understand and accept the illustration based on their experiences.
Illustrations must be relevant to the topic and content taught and must be used at the proper time.
Providing simple and understandable information should be their aim.
There should be a proper balance in the use of illustrations.
Constant use of the same type of illustration makes presentations dull, boring, and monotonous.
All students should be able to see the concrete illustrations presented.
Hence, both narrative and illustrative methods of teaching are quite beneficial in classroom teaching.
The narrative method makes use of the art of narrating an event, incident, or experience of oneself, someone else’s or using one's imagination.
The illustrated method employs words or concrete examples to demonstrate or illustrate points.
