Pondering how it is all going to work post lockdown makes me think about what school is like here as opposed to other countries.
It has always struck me as a bit eccentric that secondary schools in the UK think that moving 1000 students is preferable to moving 100 teachers. When I was in school classes stayed in their classroom for everything but PE, music, art and science. The teachers moved around from class to class. This obviously only works if classes are taught in forms, but there would be a lot less trouble if the teachers instead of the students moved classes...
Just as an aside: I didn’t have my own classroom for a year and absolutely hated it!
