Should Students be Allowed to Chew Gum in Schools? Have you ever felt that you are chewing your gum in front of people? In my opinion, I think chewing gum should not be allowed in schools. One reason, I think chewing gum should not be allowed in schools is that in their experiment, gum chewers in the eighth grade had a 3 percent increase in their standardized math scores. First evidence about chewing gum should not be allowed in schools is that chewing gum, of course sugarless, for at least thirty minutes can do the trick and could offer relief for as long as three hours. Another reason, I think chewing gum should not be allowed in schools is that the disposal of the gum when finished is also a problem, such as when it ends up underneath tables
