The tests don't purported to be "testing ability at deep literary criticism." The kids aren't learning poetry, they're reading poetry to help develop general reading comprehension skills. If you look at the STAARS curriculum for Grade 8, the tested skills include:
> Students understand, make inferences and draw conclusions about the structure and elements of poetry and provide evidence from text to support their understanding.
That's exactly what the questions are asking about: the structure and elements of the poem.
And I'm sure they do get technical writing samples to analyze. Also poetry. Why? Why not! Why not, vary it up a bit. They could have done the same exercise with Rap lyrics.
Again, I'm not sure what the problem is?
>They want to PRETEND to be testing ability at deep literary criticism.
I think you need to manage your expectations. Kids aren't going to give you 'deep literary criticism'.
I think we all know why they're using poetry, though. They want to PRETEND to be testing ability at deep literary criticism.
