A good teacher－student relationship is able to effectively further the student to a higher level in study. The teacher with patience and understanding encourages the student instead of pushing or forcing him. The relationship of this sort makes learning so enjoyable and funny that the student would work hard willingly.
However, a bad relationship seriously weakens the achievement of teaching. It discourages the student from learning, leaving him with a wrong and negative attitude towards studying. Thus, teaching also becomes an unpleasant task, which forms a vicious cycle.
As I see it, the relationship between a teacher and a student should be attached much importance to. A good relationship makes the teachers job worthwhile while a bad one ill-affects the students development, even to the rest of his life.
