Peer Review and Writing Workshops is a wonderful resource when utilizing peer revision in the classroom. The website offers instructions on conducting a peer edit workshop, as well as provides handouts ranging from the less detailed to the more complex, depending on your student make-up and their writing needs.
This activity is intended specifically for critiquing students' creative writing, namely a short story. Short and sweet, this .pdf provides three items to comment on when reading a students' work and also gives brief instructions on what to look for in a creative piece during a Short Story Peer Review Workshop.
Here is another great checklist to use when conducting peer edits, albeit this one is a bit more detailed than the other checklist provided in this collection. I have used this list too much success during a Screenwriting Peer Review Workshop.
