  2. We agree that overhead projector was helpful in the past years. Nowadays the overhead projector is not working on classrooms because it is more common to use smart board or data show. If the OHP has something wrong in the equipment or it is damaged for any reason it is too expensive and also it is too heavy for the teachers to carry it. This equipment is frail to use it.
