Help: "the best of school" poem

The Best of School

The blinds are drawn because of the sun.
And the boys and the room in a colourless gloom
Of underwater float: bright ripples run
Across the walls as the blinds are blown
To let the sunlight in: and I, As I sit on the shores of the class, alone,
Watch the boys in their summer blouses
As they write, their round heads busily bowed:
And one after another rouses
His face to look at me
To ponder very quietly
As seeing, he does not see.

And then he turns again, with a little, glad
Glad thrill of his work he turns again from me
Having found what he wanted, having got what was to be had

And very sweet it is, while the sunlight waves
In the ripening morning, to sit alone with the class
And feel the stream of awakening ripple and pass
From me to the boys, whose brightening souls it laves
For this little hour.


I'm suppose to write a critical commentary on the poem but really have no idea what to talk about. I dont really get the idea of the sea side too... and why the teacher is so pleased. We just read the "last Lesson of the Afternoon" poem and its so different from this poem. I'm suppose to give a brief contrast description of the 2 poems too.

Would you care to offer your thoughts on this poem? thanks

the second stanza and onwards, I have that same poem except mine goes like this:

With glee he turns, with a little glad
Ecstasy of work he turns from me
An ecstasy surely sweet to be had.

And very sweet while the sunlight waves
In the fresh of the morning, it is to be
A teacher of these young boys, my slaves
Only as swallows are slaves to the eaves
To the man who threshes and sows the sheaves

and I have 3 more paragraphs after that. This is the same poem, weird.
