The document discusses peer editing, which involves students reviewing each other's writing to provide feedback for improvement. It explains that during peer editing, students read each other's work, comment on strengths and areas needing clarification or development, and may discuss revisions. The purpose of peer editing is to get an outside perspective to help writers better organize their ideas, address any issues with understandability, and identify unnecessary information. It suggests peer editors ask questions politely and mark important elements like the topic and concluding sentences.
