The schools of today are trying to cope with the changing times by employing modern gadgets in their teaching method. Some teachers no longer write on blackboards not only to avoid allergy attacks in the classroom but also because they found a more efficient way to present their lessons. Teachers have become high tech already that they bring laptops to school and make a Powerpoint presentation about their lessons. Then with the use of a DLP projector, the lessons are then projected on the white board and the teacher talks with ease as her presentation is backed by a visual or sometimes audio-visual presentation. Cool, huh?
