This document discusses various forms of nonverbal communication that teachers can use effectively, including facial expressions, eye contact, gestures, posture, proxemics, paralinguistics, and appearance. Maintaining eye contact, using gestures to reinforce messages, varying tone and being aware of body language can help teachers clearly communicate and build relationships with students. When expressing dissatisfaction, a teacher should make eye contact, stand closer, vary paralinguistics and use "I" statements. Active listening skills like affirming ideas and paraphrasing help teachers understand students and address issues respectfully.
