When you ask your kids to do peer-editing do they write "good job" at the top of the page and call that effective critique?!
This trio of peer-editing charts will help your students critique one another's creative nonfiction articles/essays. There is one for personal experience/autobiographical incident writing, one for humor writing, and one for informative/expository writing. Each chart has space for two separate peer critiques. (You could also use one space for self-critique and one for peer).
I use these with my creative writing students during our creative nonfiction unit; however, you could use them with any English or writing course.
