the impact of the teachers’ non-verbal communication on success in teaching

introduction: non-verbal communication skills, also called sign language or silent language, include all behaviors performed in the presence of others or perceived either consciously or unconsciously. the main aim of this review article was to determine the effect of the teachers’ non-verbal communication on success in teaching using the findings of the studies conducted on the relationship between quality of teaching and the teachers’ use of non-verbal communication and also its impact on success in teaching. methods: considering the research method, i.e. a review article, we searched for all articles in this field using key words such as success in teaching, verbal communication and non-verbal communication. in this study, we did not encode the articles. results: the results of this revealed that there was a strong relationship among the quality, amount and the method of using non-verbal communication by teachers while teaching. based on the findings of the studies reviewed, it was found that the more the teachers used verbal and non-verbal communication, the more efficacious their education and the students’ academic progress were. under non-verbal communication, some other patterns were used. for example, emotive, team work, supportive, imaginative, purposive, and balanced communication using speech, body, and pictures all have been effective in students’ learning and academic success. the teachers’ attention to the students’ non-verbal reactions and arranging the syllabus considering the students’ mood and readiness have been emphasized in the studies reviewed. conclusion: it was concluded that if this skill is practiced by teachers, it will have a positive and profound effect on the students’ mood. non-verbal communication is highly reliable in the communication process, so if the recipient of a message is between two contradictory verbal and nonverbal messages, logic dictates that we push him toward the non-verbal message and ask him to pay more attention to non-verbal than verbal messages because non-verbal cues frequently reveal the intention of the sender of the information and reflect his/her emotional reactions. based on the obtained results of this study, it is recommended that attention to non-verbal communication skills can make a positive change in the future of a student’s life. it seems necessary for the teachers to practice and learn effective communication skills, especially for those who always interact with a large group of students. one of the factors contributing to the success or failure of students is the quality of the relationship and how the teacher builds this relationship with students. especially, it is more effective for students who are more responsive to human relations and communication skills. finally, it is recommended that the teachers should improve their communication skills to have better communication with their audience. the authorities are recommended to help improve the teachers’ level of communication skills through holding training courses.
