I think a positive teacher-student relationship is a guider-learner relationship. Teachers should not dominate in the relationship but are prepared to help and guide students when there is a need. Teachers should not set a standard for all students, but encourage excellence in diversified ways. Students need to realize that they are not studying for anyone else but themselves, the key is to find the motivation of studying. What is crucial is not how much knowledge you've remembered, but mastering the way of learning.
