Classrooms were one of the places that stayed relatively untouched by technological revolution. Sure, there were computers and projectors that came along. Teachers aided their teaching regimen with presentations. Universities saw digitized examinations, online submission of assignments, library management systems and sometimes, the implementation of ERPs. But majority of the actual teaching still happened and happens with the help of physical aides. The teacher always needs to go to the board and engage his or her chalking skills to elaborate upon a point. While that is handy and gets the job done even in large corporate auditoriums, it is not the best thing for classrooms.
