- Studies reveal that as much as 85% of classroom communication is nonverbal. This course consists of eight entertaining modules that include audio tracks, animation and interactivity. Topics include the importance of nonverbal communication in the classroom, as well as our everyday lives. The modules describe the use of body language, effective vocal cues, proper appearance and the effective use of space (proxemics) and time (chronemics). A variety of support materials accompany the modules, including an assessment tool that instructors can use to evaluate their nonverbal skills.
