which ones do you know that are already teaching all years face to face?
What a lot of HE bashing parents don't seem to understand is that universities are independent institutions. There is no national curriculum.
And furthermore, we are subject to the law of the land - together with the fact that government pronouncements on HE are an afterthought. We are often having to develop our practices via reading press releases eg. the 3 day pivot to total online teaching in January 2021. There was no consultation with HE leaders. We did not know until the gov't announcement what HE would be required to do.
Since at least February 2020, university staff at all levels - from senior management teams to department teaching & admin staff - have been developing plans & scenarios to meet several possible sets of national guidance. We still are.
The communication with students at my institution has been regular & thorough, and has explained our reasons for doing what we are doing - this is at both institutional & departmental level. I suspect many students are ignoring emails, and venting to parents.
And as for "confined to rooms" - all students in university or private housing are in designated bubbles or households. I live adjacent to a an area of student rental houses in my town, and I see groups of students all the time - outdoor parties and groups in town.
