I'm only a second year teacher, but the majority of my experience has been with very reluctant learners. I learned that I had to find/make lessons and activities that get kids up and moving around to keep them from messing with each other. Plus they enjoy coming to class when the know they won't be stuck in their seats.
I stick with my college motto in my classroom: "Learn by doing."
