Critiquing in a writing class serves several purposes:
Critiquing is about readability-not the reader or the writer. Therefore, remarks about the reader's choice of topic or the reader's or the writer's beliefs are inappropriate, as are suggestions based on a reader's experience with a similar topic. It doesn't matter if you too have been to England, owned a dog, or lost a parent. You cannot say, "If this was my piece . . ." You can say, "I became confused here, or this piece became slow there." We must remember and respect the writer's right to take on different subjects and content. We, as readers, are there to comment on what elements make us as a reader more or less inclined to continue reading.
Also we are not grading a piece of writing or enforcing so-called rules of good writing. Instead, think about ways in which you can comment on the piece and suggest to the writer how their piece can become irresistible to read. And, don't feel that you have to solve the writer's problems. Ultimately, the writer must determine what the piece is about and how it should read. Finally, a writer can break any rule with which he or she can get away.
Here's how to proceed:
The Five-Step, In-Class Discussion format:
If, during class discussion, you find yourself arguing, stop. There are no right and wrong ways to see a piece. Discussion is not about you, the reader. Analyzing a piece is not the point, either. Readability is the sole purpose of critiquing. Also, you may not be the audience for this piece. If you still can't let go of your position, make your argument a writing assignment.
Critiquing is an opportunity for the writer to hear different experiences from different readers . . . then determine which comments will help advance the piece.
