One of my practicum supervisors told me that you know you've given enough homework when the students start complaining. It surprises my students sometimes as usually the homework in other classes gets piled on if they complain.
So we're always told at Pro-Ds that we shouldn't be teaching kids to use the tools of yesterday and instead teach them to use the tools of the future. Yet at all the schools I've been to, most teachers and admin do everything they can to get rid of the tools the students will be using once they are out there.
