If we start dividing kids into groups, these are probably the kids that would be put into the "extra needs" group. We do not need to be dividing kids further and creating more separation in the school system. We are already trying to overcome huge gaps that created lasting differences between student achievement. We have least restrictive environment for a reason. These students can and want to succeed, removing them to the "special" unit is not going to achieve this. Put all the disruptive kids in one class and what expectation are you setting for that period? What message are you telling the students, they can't learn?
Is the goal to help those students or remove them so others can learn. Sure, other classes will run more smoothly, but these will fall far behind. Yeah, it worked in the Wire, but schools are not Emmy nominated TV shows. Who will teach these students? If teachers can't handle three at a time, how will the teacher handle 26 at a time? It is not about separating out the bad, it's about supporting teachers, additional resources and the bigger issues in schools to successfully instruct all students in a classroom.
These kids do not need to be removed, they need positive motivation, encouragement and a school that believes in them.
