So I sort of knew what his comments might be even before I got them back. On drafts of student papers, provide specific written comments that students can use when they revise. Not a mark on the whole thing. That doesn't do me any good. I want to see meaningful feedback.
Instructors can guide students by modeling how to respond to papers.
You had to write your papers and let other people read them. And it felt good to see good comments from peers. You know, because usually only your teacher will see it. But it's good to see what your peers say about your writing. If they agree, I must be doing something right.
