I want my students to learn how to edit each other's work. I tell them that professional writers know they don't catch their own mistakes and have others look over their work before submitting it for publication.
I am a third generation public school teacher who has been in education since 1987. I have taught elementary students full time for 20+ years. I am also a freelance curriculum writer. You can contact me at mrs.mjbauer(at)gmail(dot)com.
