Curt says that the nonverbal communication is so important to the teacher that it has a relationship with the attitude that students hold toward the school. According to the study, if the teachers learn how to use the nonverbal communication more effectively, then the relationship between teachers and students can improve greatly. Besides this, students can also increase their cognitive ability and efficiency of learning. (Cooper, 1988). .
Besides, in school education, nonverbal communication plays a positive role in cultivating the students' characters. Teachers are usually respected, and factually, what or how the teachers say and do will be possibly imitated by the students (sometimes subconsciously). In a word, teachers' graceful nonverbal communication helps to improve the students' artistic-appreciation and moral character. If the students develop a wonderful nonverbal communication, which will possibly leads them to form an optimistic and active feelings, they will surely have a more smooth interpersonal relation.
The affection of it on the students is reflected not only by establishing a good example, but also shortening the teacher-student estrangement by which a more harmonious studying atmosphere is created. As a matter of fact, teachers' friendly appearance can greatly encourage the students' studying enthusiasm. Furthermore, the characteristics of theoretic and abstraction of knowledge also requires the vivid, dramatic and accessible gestures to make it specific and figurative. As a result, the students' interest is motivated and the effect of teaching is greatly improved. In the process of analyzing the performance of the students in the classroom, we find that nonverbal communication (such as the smile or the facial expression) of the teachers can arouse more reaction and draw more attention from the students. If they use some appropriate gestures when they deliver the lecture, their class can be more lively and interesting.
