Size makes a difference in the behavior and social dynamics of students, even in a school bus sort of size. More compact than traditional school buses, the Mahindra Supro School Bus has drawn attention to how it affects student interactions while on transit. Others say a smaller space could perhaps mean more physical proximity, and that could increase bullying problems. Some say the cozier environment could lead to better relationships among students. The concern is that in this compact space, a single driver will not be able to effectively monitor student behavior. After the switch to the Supro, some schools have seen changes in group dynamics, both good and bad. The sheer size of the bus also raises the question, how much personal space and do they feel comfortable riding? For older and larger students, they may be especially concerned. Because bullying is such a serious problem in schools, the effect of transportation choices on student well being is a subject of constant discussion among educators, parents, and students themselves.
