ASSIGNMENT FOR THE SESSION 2021-2022

Class: XI Subject : English Assignment No. 1

I. Education facilitates learning by creating opportunities which help in acquisition of

knowledge, skills, values, beliefs and habits. Acquiring bookish knowledge is not the true

essence of being educated. Education is much beyond achieving degrees. It is more of

inculcating values – moral and social , developing a positive outlook and building great

humans with great characters.

There are various aims of education–social, vocational and intellectual. Social aims of

education emphasize more on the welfare of the society rather than of an individual .Society

is the whole and each one of us is a part of the big whole .We must work towards the

benefit of the society. It stresses on the welfare of the state and ensures that people posses

virtues like co-operation, loyalty and sacrifice.

The vocation aims of education create an environment suitable to hone the skills of a learner

so that one emerges as a better worker in the field one wants to excel into .They become

better workers by acquiring all the required skills.

The intellectual aims of education make the learner confident so that he or she can lead a

confident life. They aim at providing enough opportunities so that innate intellectual

capability of a learner can reach the optimum level. They provide the best environment for

the intellect to grow and direct towards the right track.

Without education ,humans will be wandering aimlessly groping into the dark and looking for

some light to illuminate their paths to development.
