Hypothetically, if you were going to loop up with the same group next year, knowing every group has its assortment of wonderfully behaved kids and "beloved rascals" (as Whole Brain Teaching calls the troublemakers, haha) would you rather: A) keep the class as is, knowing that you've built relationships even with the difficult students, or B) mix up some students, swapping some of your more difficult kids with another teacher's, knowing they may do well with another teacher or group? or even C) not keep the class at all and completely randomly regroup and redistribute the students, knowing you'd have some of the same but not as many. I'm leaning towards A. Not sure whether this is a real scenario for me, but it's a possibility. What would you choose?
