This document summarizes Jeremy Harmer's book "How to Teach English" and provides guidance on teaching writing. It discusses that writing is important for language development and reinforces visual and mental skills. Teachers should consider students' interests and abilities when assigning writing tasks. Writing sequences should start simply and become more complex, from elementary to advanced levels. Teachers are advised to correct writing by having students self-correct or using symbols rather than red ink, and to accommodate different handwriting styles when possible. The document also notes that writing fits well into the "Engage, Study, Activate" teaching model and can promote literature and journaling.
