Nonverbal communication in the classroom can produce subtle nonverbal influences, particularly in the affective domain. In Suggestopedia, double-planeness (the role of the environment and the personality of the teacher) is considered an important factor in learning. Suggestopedic teachers are trained to use nonverbal gestures in their presentation of the lesson material and pantomime to suggest the meaning of new words in an unknown language. Positive facial expressions, eye contact, and body movement are used to project self-confidence and competence. Verbal and nonverbal behaviors are harmonized so that students receive the same positive message of support and encouragement on both the conscious and unconscious level. Voice qualities of the teacher and environmental factors are also emphasized in the suggestopedic method. Number of students, seating arrangement, wall colors, physical distance between teacher and student(s), and lighting are all considered. Suggestopedia incorporates the main elements of modern, Western nonverbal communication theory, although there is no evidence that its developer, Georgi Lozanov, was influenced by it at the institute in Sofia, Bulgaria. Areas which have a bearing on Lozanov's Suggestopedia and which are discussed are: paralanguage, kinesics, proxemics, environment, and oculesics. (Contains 28 notes and references.) (Author/NAV)
