As it will always be in the classroom, some students are more motivated and adaptable than others. I've learned over the years that alienated and disruptive students might need a little more personal coaching and reminding of protocol to make them more agreeable. A little understanding goes a long way.
I also have everyone understand that their focus needs to be on their classwork and not outside happenstances. Life occurs...but our class is an oasis of cooking and cooperation for a few hours a day. If there is truly a disruptive and violent student then policies are in place to deal with that.
