The benefits of reviewing one's work are undeniable. However, students often struggle to give specific and useful feedback for their peers that go beyond 'Good job;' 'Nice examples,' or 'Watch spelling.'
This is a cover page that I use frequently in my classroom. I have two folders pinned to the bulletin board at the back of the room: one is labelled Oral peer review sheets and another reads Written peer review sheets. All student work (compositions, presentations, etc.) must be accompanied by a cover sheet to demonstrate that their work has been reviewed prior to submitting their final copy. In the case of oral work, peer reviewers can either listen to the oral presentation live, or they can listen to a recorded version of the assignment via youtube or shared via the recording device (iPhone, iPad etc.).
I like using this cover page because it encourages self and peer review as well as accountability and independence. The author of the work must decide on specific elements they would like feedback on which encourages self reflection on his or her relative strengths and weaknesses. This focus then allows the peer reviewer to give more specific and relevant feedback related only to these elements. Best of all, these sheets can be applied to any written or oral task and students can access them when they are ready, allowing me to focus my time on students needing greater support!
I have seen great success with these self/peer review sheets - I hope you find them useful too!
