Metacognition is a typical learning outcome in composition courses, but providing feedback on low-stakes reflective writing and assessing highstakes reflective writing are complex tasks that warrant more attention in the literature. Consequently, this article explores how the assignment of and response to low-stakes reflective writing can provide effective scaffolding to higher-stakes reflective writing tasks. We present an example of our strategy for response through one instructor’s experience with responding to her first-year composition student’s low-stakes reflective writing. Ultimately, we call for more research on responding to reflective writing that will ensure the valid and reliable assessment of metacognition in composition courses.
