In addition to using language to transmit knowledge to students,the non-verbal behaviors of primary school teachers,such as teachers’attitude and body-posture,also transmit different information to students,presenting multi-dimensional values:establishing students’behavior norms,stimulating students’learning motivation,and building a harmonious relationship between teachers and students;in order to further optimize the classroom non-verbal behaviors of primary school teachers,we should improve the unity of non-verbal behavior and give full play to the flexibility of non-verbal behavior.
