@homerdog , the way schools are being opened in Germany has very little relevance to residential college life as it has been so far.
Class sizes have been halved, groups of no more than 15, in many cases no more than 10.
Schedules have been staggered (beginning and end times, elementary kids go every other day, older kids every other week).
Juniors and seniors have classes only in the three subjects they take written exams in, once those are done, the two classes they take oral exams in (comparable to IB, with HL and SL classes).
Grades 2, 3, 7, 8 and 9 haven’t come back at all yet.
All specials and extracurriculars cancelled.
Every group stays together in the classroom for as long as they are in school, the teachers move. Designated bathrooms for the groups. Recess and PE in the same groups, outside when possible.
Desks spaced out in the classroom, windows opened every 45 minutes, masks in the hallways.
In effect, they have created little bubbles of ten, so if a student tested positive, relevant exposure would be limited to the bubble and the few teachers they have had, all of whom have distanced themselves.
And don’t forget, everyone’s come out of isolation. No one has traveled for months.
Everything after class, the school can not control. That I think is the biggest danger. H teaches High school and says students are super disciplined in the classroom, but start congregating without masks after class. The teachers disperse them, but out of the building, they have no jurisdiction.
If a college we’re to recreate that, they’d have to welcome all students on campus who they eventually want to house in doubles and put them In singles first, Test, isolate for at least 10 days, test again.
Move them together in doubles, deep clean singles, welcome the rest, test-isolate-test them first.
Everyone chooses one online class and on F2F class, with dorm composition determined by F2F class. Create bubbles, with staggered class and mealtimes. Everyone must distance with everyone outside the bubble. Apply for permission to leave campus. If there is an outbreak, test and isolate the relevant bubbles.
If you have no outbreaks after 7 weeks, you ca have another two F2F classes. If there are, online classes for the rest of the semester.
I do not know how many colleges have the resources/dorm space/independence from the community around them to set this up.
