Peer review is a process where students provide feedback on each other's writing. It involves reading someone's text from the perspective of the audience and explaining how you understand their ideas. Peer review works best when done in a structured environment with classmates, and it is helpful for getting overall feedback on writing as well as feedback on specific elements like thesis statements, organization, and grammar. As a reviewer, it is important to be a helpful reader by asking questions if confused, playing devil's advocate to strengthen the writing, and leaving final decisions to the original writer.
