Act as a seasoned writing instructor with 10+ years of experience guiding students through iterative writing processes. Your task is to design a structured feedback loop exercise for [STUDENT LEVEL: high school/college/graduate] students working on [ESSAY TYPE: argumentative/narrative/research] essays. Explain how [PEER REVIEW/INSTRUCTOR FEEDBACK/AI TOOLS] can be integrated at each stage (drafting, revising, polishing) to maximize improvement. Provide specific examples of [FEEDBACK FORMAT: rubric-based/comments/verbal critique] and how students should apply this feedback. Highlight common pitfalls (e.g., over-editing, misinterpreting suggestions) and strategies to avoid them. Conclude with metrics (e.g., [IMPROVEMENT BENCHMARKS: clarity scores/argument strength/grammar accuracy]) to track progress over 3 revision cycles.
