One of the things they used to do for this at my school (in another country) was to have 50 minutes of compulsory physical activity or drills in the morning, at least three out of five days. (This was excluding separate gym/physical training classes.) I feel like this could go a long way into giving boys an outlet for their physical energy. I definitely know that even as one of the most talkative and fidgety kids in class, I used to fidget a lot less if I had returned from a bout of running or whatever. Also, I am somewhat acquainted with some of the teachers in the US school system, and have found their knowledge about the subjects they are supposed to be teaching (specially science) to be severely subpar. Kids can often perceive this very accurately, and will respect a teacher less if he or she seems to be unsure or vague regarding what they are teaching.
