There are better solutions. Meditation in schools is highly effective at reducing school violence and increasing concentration for learning. Higher quality nutritious and organic foods, rather than processed snack foods and fast foods, when served in school cafeterias are another part of creating an environment more conducive to the needs of children.
The most common sense, natural solution to inattentive behavior in school children, however, may be the basic idea of giving children more time to free play and to engage their bodies in physical activity. It's such a simple notion in such unusual times that it actually sounds revolutionary, and several schools in Texas are being hailed for trying a new program which solves behavioral problems by doing nothing more than allowing children to play outside more often during the school day.
Simple ideas like this have been proven to work well in places like Finland, where students' test scores improved along with increased play time, a case which serves as the inspiration for a program in Texas schools which have quadrupled the amount of outdoor recreational time, seeing amazing results in terms of overall increase in focus and decreases in distraction and behavioral interruptions.
Comment: Kudos to these schools. Children should be outside playing and not forced to sit at a desk for hours on end.
Kids need less class time and more play time in school
