Our present education system is teacher-centric. It is easy to understand why it is so if you consider that it has historically been very expensive to gain and transmit knowledge. Information -- the foundation upon which knowledge rests -- was in limited supply. A teacher, together with a limited set of books, was the knowledge base which anchored the education process. The teacher was the active agent, communicating information to the students, the passive receptors of information. Learning by rote was the method most favored because the information was largely disjointed and the student was not really quite sure what the motivation behind knowing all those disparate facts was.
