Since you're a researcher in the field, what would you suggest a teacher (specifically an after-school "enrichment" teacher - who cannot give grades and/or homework) do to maintain better classroom control? I'll be honest, I'm getting to a point where if there's a boy in my class, he gets one class session to prove whether he's one of the loony kind or will actually focus - and then almost completely ignore him and his behavior if the former. It's not good for the kids, it's not really a productive thing on my part, but it's been the only thing that works.
Occupational therapists can be particularly helpful in working out accommodations like bouncing balls for seating, balance boards, fidget devices, etc, that can provide extra stimulation that allows kids with ADHD to focus.
I went through OT for eye-hand coordination for several years. I wish I had the means to provide that level of accommodation or to successfully convince my schools to do so.
