Despite support from some research studies and educators, gum chewing is typically banned in schools, as many educators believe it distracts both the gum chewer and surrounding students. Some students chew gum with their mouths open or blow bubbles, which can impede communication from the teacher to students.
Along with the noise distractions, gum is a potential tool for littering a classroom. Students may stick stale gum under desks or on the floor. Improper discarding of gum leads to sticky messes. Some educators also believe that chewing gum is a bad habit that shouldn't be allowed to gain traction in schools.
