Virtual School 4.0
An online school (virtual school or cyber-school) teaches students entirely or primarily online or through the internet. An online school can mimic many of the benefits provided by a physical school (learning materials, online exercises, self-paced courses, live online classes, tests, web forums, etc) but delivers these through the internet. Physical interaction by students and teachers is unnecessary, or only supplementary.
School staffs can work on virtual platform to produce the best teaching performance.
