DD is a high school junior in an IB program. Started about a week ago. DD came home and said that her Spanish teacher wants parents to sign off that students worked on their homework for 45 minutes. DD finds this insulting. I think that my signature is meaningless in this context. I do not monitor her homework. DD has been completely independent in scheduling her time and managing her homework for YEARS. She is an excellent student. Do I say something to the teacher or do I just sign off?
