If a person has the strong ability of self-study and self-discipline, well, he/she probably could study by himself/herself. But it not means that computers should replace teachers. Because we could learn not only information form teachers but also study skills and other things form teachers. Computers as well as provide some software which teach some study skills. But computer cannot personally understand the student’s circs.
For example, a student studies the English grammar. He searches lot of grammar exercises form internet to practice himself. He get some questions correct and some incorrect. He has to know why he got those incorrect. For some questions he could get answers form the answer sheet. Maybe he would not know why he got those incorrect even though he had the answer sheet. At that time, he need get help from a teacher. The computer cannot explain his personal questions and cannot provide his personal skill to his questions.
