We can have more chances to do it in only four years. It is because would-be teachers must study their special field of study, such as English, social science and so on in university, so we cannot learn other subjects, such as child psychology. Teachers who cannot understand feelings of students are increasing now because of lack of education. I think that a six-year teacher-training program can prevent such teachers.
