Maybe? The major, MAJOR difference is that if a kindergarten class is in front of a teacher, the teacher can see the class and there are consequences for misbehavior / disobedience and the teacher can manage the class. The teacher has tools for making the kids pay attention that don't really seem possible over a longer-term Zoom meeting.
The kids require supervision by parents on the other end of the call to achieve even close to this (the parents don't have the same "classroom management" skills), so I figure... "Might as well do it myself". That's the main Zoom vs. Kindergarten difference.
