Actually, these methods are quite antiquated. Computers, screen projectors, PowerPoint presentations; now this is the technology that can take over as effective teaching aids. I haven’t seen an actual chalkboard since I left high school. White boards with erasable markers are the norm if used at all. Overhead projectors that use transparencies are pretty much a thing of the past accept for schools that can’t afford anything better.

ofcourse, the OHPs and the LCDs can prove helpful in aiding the students to have a better look at the visuals and avoid time wastage of drawing the sketches in classroom but they can no waybe a permanent replacement for the chalkboards
