How do I discuss different interpretations or readings of a text in an essay (text response), specifically, twelve angry men by Reginald Rose..thanks!

When my students were learning about Literary Analysis in
College Composition,  we read Anthem by Ayn Rand together as a
class.  Anthem is a short, easily read, but very thought
provoking, dystopian novel.  It is filled with great discussion fodder. You can also
receive a classroom set of it free through the Ayn Rand
Institute.

Then as a class we looked at it through many
different lenses.  We discussed how it would work with Reader Response,  with
Deconstructionism, with Feminisim, with Marxism, with Historical Analysis, et cetera.
 We discussed this in depth, using only one or two of the literary theories a
day.

After they had a firm grasp on the many different
'lenses' they could look at a text through,  we moved on to a classic book of their own
choosing. They each wrote an essay about the book using the Literary theory of their
choice.  It was highly effective, and I felt I had prepared my seniors for how to write
about a book on a college level.

Good luck to you with your
lesson.
