James described children like this: “Sensitiveness to immediately exciting sensorial stimuli characterizes the attention of childhood and youth. . . . the child seem[s] to belong less to himself than to every object which happens to catch his notice.” Overcoming this tendency to flit around is “the first thing which the teacher must overcome.” This is why it is so important that schools go phone-free for the entire school day by using phone lockers or lockable pouches.
