Its probably OFSTED.
But that doesn’t mean that it doesn’t make sense to print it out. Say the teacher wanted students to try question 3 again in class. Or the teacher wanted to circulate talking to students about problems they had with the home, they might all of course done different home work each week
Also even without OFSTED its not to crazy for all of a students work to be available on one place
Last week a student sent me their home work as a pdf from his microsoft surface. I printed it out but politely asked him to print it out for me in future
Oh and finally
the teachers can obviously then see it and assess it online.
Your not use to education software aren’t you. I worked in school that spent a fortune on electronic registration software, oh and a laptop for every member of staff to run it on
About a few months into its use I set out to find out if a girl in my tutor group was going to English regularly. After 2 hours of asking everyone how I went about this I was given the answer that the only person who could see if she went to English, was her English teacher. At a trade fair I asked the sales man of this software if this was true and he admitted it was. Of course a search for the information could be written, but we din’t have anyone who could do this.
So no I wouldn’t assume that the teacher gets a sensible view of the home work from the other side unless you’ve been specifically told that they do.
I have further similar stories of educational software
Not sure of this reflects more badly on the public or private sector
