WINTER HOLIDAYS’ HOME WORK 2017-18

Read the passage below, and answer the questions that follow. Paste the worksheet in your

HW copy.

While conducting a workshop in a school, I was shocked to see that children were punished if

they drew mountains without a scale. Each hill had to be of the same size and if any student

looked out of the window and drew the landscape as it appeared before his eyes, he was

given a ‘zero’ by the drawing master. In India, once art and life flowed in one graceful

balanced line, but now there is a total neglect of art in education.

According to Indian classical tradition, a person was considered properly educated and

cultured only if he was fully knowledgeable about all the sixty-four arts listed in the scriptures.

Today there is an urgent need to reintroduce art education in school curriculum. All children

have a vivid imagination which makes them natural artists. Unless this skill is allowed to grow

it will never reach its potential. Most children become conscious of their artistic skills after the

age of eight. Till then they draw and paint with immense enthusiasm and are confident about

their art. Like seedlings they need to be protected and sheltered at this stage. An insensitive

remark kills this budding talent and the child will never be interested in art again.

Creativity is a misunderstood word. Creativity in education is even more ambiguous. The aim

of art activities is not to make the child an artist. In fact, most children will not be interested in

professional careers as painters and will choose more conventional professions, but a good

art education will help the child to grow into a more sensitive adult. It will enable him to acquire

knowledge on a different plane, develop communication skills and express ideas through non-

verbal means, since visual art is a highly effective tool to communicate in an abstract and

multi-dimensional way. It will help the child to look at his world with new eyes and develop

keen powers of observation.

Art activities need not always be isolated. There are many meaningful ways of integrating

visual art experiences with the study of other disciplines. Language, science, mathematics

and even basic hygiene can be taught through creative art workshops. Original thinking,

diversity of creative expression and freedom of expression will enhance the learning process

and allow the child to experience art at its best and most rewarding form. It is the responsibility

of teachers, artists and parents to ensure that even the most simple art activity is carried out

with care to enable our children to grow into good human beings.

a) The problem with Indian art education, nowadays, is that ……………………….

b) Indian tradition would consider a person educated only ……………………………………..

c) All children are natural artists because ……………………..

d) The child loses interest in art when ……………………..

e) A good art education helps a child ………………………….

f) A child can express ideas through non-verbal means because …………………….

g) The learning process can be enhanced by …………………………...

h) A word in the passage that means callous ………………………

i) A word in the passage that can be replaced with puzzling ……………………

j) What is the antonym of the word enhance? …………………………..
