It is fairly common practice for TAs in my school and previous school to 'support' SEN or early writers by writing out a sentence (usually on a small whiteboard) that a child says and then child copies it. The children often 'have a go' at independent writing in literacy lessons but not in other lessons. I prefer to either ask the child to tell me what they've written and then write it myself or write what the child says and then give them a different activity or let them have a go at writing another sentence. Is there any value in children copying sentences? Am I missing something? i just think if someone is going to write the sentence they may aswell just do it in child's book in quotation marks and let the child get on with something more useful than copying.
