Step-by-step explanation:
In the Say Back Strategy, classmates should jot down notes about your writing during the first reading. This initial engagement with the text allows them to capture their immediate reactions and understandings, which is crucial for providing substantive feedback. They must approach your text as impartial readers and note their responses to the content, organization, and clarity of your writing.
After the first reading, they can exchange questions and insights with you, helping to guide the substantive revision process. This peer review is part of the writing cycle that includes drafting, receiving feedback, revising, and editing.
