Poems are considered the windows that let us look into the mind of the poets. The poems included in the syllabus of the CBSE English are chosen to deliver such bliss to students. One such poem is in the Class 12 syllabus named ‘An Elementary School Classroom in a Slum’. This poem is written by Stephen Spender, one of the eminent poets who perfectly described their political, economical and social views through his creations. This poem reflects the communal disharmony and inequalities in society. It reflected in the deepest corners of the slums where the kids had to go to a school in a rugged room.

The poet Stephen Spender has written the poem ‘An Elementary School Classroom in a Slum’ and published it in 1964. The lines of the poem describe how deteriorating the condition of a slum school is. His views related to social norms, politics and children of the slums resonate pretty well in the lines of the poem. He witnessed the pain in the eyes of the children visiting the school to study.

As per the Elementary School Classroom in a Slum Summary, the poet saw the kid coming from different families living in the slum to study. They had bright eyes but were marred by malnutrition and poverty. They have the eyes to dream but not the platform to make them come true. He saw one kid, sitting in the corner at the end, with bright beautiful eyes. He saw dreams and sparks in those eyes but covered with utter despair.

The classroom was very dirty and the walls were made of mud. People donated charts for studying. There was a poster of Shakespeare and his bald head. There was beautiful scenery of Tyrolese Valley hanging from the wall. There was also a world map hanging from the wall. It is not the same world they live in.

The poet expressed his pain that these children will always be stuck in the slums and will not be able to see the light of hope. Their future is dim and they have no options but to follow the footsteps of their parents. He was disappointed with the social system. Nobody cares about these children. An Elementary Classroom in a Slum Summary tells us that the poet understood that the kids do not even know who Shakespeare is or where that valley is located. They were not loved or cared for. At a very young age, they are forced to work. Most of them end up mingling with the wrong groups. They commit crimes in search of love and attention.

In this Summary of Elementary School Classroom in a Slum, we see that the kids are very thin. They are malnourished and their bodies are weak. The bones can be seen prominently protruding. The glasses they use to drink water are cheap and very heavy. He feels very sad as there is very less probability that these kids will someday overcome poverty and lead a good life.

In the Summary of the poem An Elementary School Classroom in a Slum, he focuses on the government and societal norms that create slums. There are no steps taken by the government to remove the slums and give these people a better life. The government is not willing to bring any change which restricts these innocent lives inside the boundaries of these dark alleys. The poet wants the kids to witness the beauty outside in the real world. He wants them to feel the green nature and play in the fields.

Conclusion:

According to The Elementary School Classroom in a Slum Summary, the poet wants the children to become successful in their lives by making their dreams come true. He wanted those bright eyes to become capable enough to dream. This poem teaches us the value and importance of education in everyone’s life.

Gandhiji says that an action done for considerations of comfort and personal happiness in another world is non-moral. That action is moral which is done only for the sake of doing good.

Interpolation is the technique of estimating the value of dependent variable (y) for any intermediate value of the independent variable (x). Extrapolation is the technique of estimating the value of dependent variable (y) for any value of the independent variable (X) which is outside the rouge of the given series.

1. Aggregate Expenditure Method (A.E.M). 

2. Family budget method (E.B.M.).

Normal equations are :

na + bΣx + cΣx² = Σy.

aΣx + bΣx² + cΣx³ = Σxy

aΣx² + bΣx³ + cΣx⁴ = Σx²y

Let x be the numbers students opted first language kannada is a Binomnal variate with the parameters.

n = 4; P = 40% = 0.4; q = 1 – p = 0.6 and N = 20.

The p. m. f. is P(x) = ⁿC_xP^x q^n-x = 1 – p = 0.6 and N = 20

P(x) = ⁴C_x(0.4) x (0.6)^{4 – x} ; x = 0,1,2,3,4

Number of teachers will report 2 or more students opted for first language kannada

= P(x = 2) + P(x = 3) = ⁴C₂(0.4)² (0.6)^{4 – 2} + ⁴C₃(0.4)³(0.6)^4-3

= 0.3456 + 0.1536 = 0.4992 × 20 = 9.98.

1. There are no sudden jumps in the values of dependent variable from one period to another. 

2. There will be no conscutive missing values in the series.

Analysis of time series is useful to 

1. Understand the past behaviour of the data. 

2. Predicting the future trend.

Linear equation is: y = a + bx

Normal equations are : na + bΣx = Σ y

aΣx + bΣx² = Σ xy.

na + bΣx = Σy

aΣx + bΣx² = Σxy.

The conditions are: 

• The values of the independent variable (x) should have a common difference, i.e., in A.P. 

• The value of ‘X’, for which the value of’Y’ is to be interpolated must be one of the value of x.

• Registration method 

• Census method.

Interpolation is the technique of estimating the value dependent variable(Y) for any intermediate value of the independent variable(X).

Extrapolation is the technique of estimating the value of dependent variable (Y) any value of independent variable (X) which is outside the given series.

1. There are no sudden jumps in the values of dependent variable (y) from one period to 

2. There will be no. consecutive missing value int he series.

Let the monthly incomes be 2x and 3x respectively. Since their savings are Rs. 100 each their expenditure would be 2x – 100 and 3x – 100

∴ \(\frac{2x - 100}{3x - 100} = \frac{3}{5}\)

10x – 500 = 9x – 300; x = Rs. 200 

Hence the monthly income of A = 200 × 2 = Rs. 400 

The monthly income of B = 200 × 3 = Rs. 600

d) Creates movements of the sensory hair cells, a) Generates impulses. 

c) Impulses are transmitted by the vestibular nerve to the cerebellum.

f) Cerebellum coordinates muscular activities.
