Educational pods

What is the optimal size for a learning cohort that offers positive returns to social interaction but allows for distancing?

Dunbar’s number is 150.

Average student/teacher ratio is 16.

A military squad is 8-12 people.

CDC’s number for gatherings in times of COVID is 10.

So, 10?

Could a system of 10 people in a learning cohort include a ‘mentor’ that was able to tap into a larger organization of cohorts and mentors with teachers/editors providing support to create an educational experience that was at least as good as the current scenario?

If these groups were placed together in relative isolation for 2 week chunks, they should be able to then come together for larger gatherings. By allowing themselves to be isolated and monitored within the smaller pod, they could trade for future benefits like attending a festival with other pods.
