Title: VISUALLY PERCEIVED NONVERBAL BEHAVIORS OF TEACHERS AND THEIR RELATIONSHIP TO AFFECTIVE RESPONSES OF STUDENTS

This investigation was designed to measure certain visually perceived nonverbal behaviors of teachers in an effort to learn the relationships between these behaviors and the affective responses of students to the teachers, To this end, teachers were videotaped, and the tapes were shown to students for their affective responses. Thirty teachers, at different grade levels and with different subject matter affiliations, were videotaped while teaching one of their own classes. These tapes, ranging from 15 to 35 minutes in length, were edited to produce two taped episodes of five minutes duration for each teacher. In addition, 15-second segments, to be used as mea-sures of first impressions, were prepared for each teacher. To measure the nonverbal behaviors displayed by the teachers an instrument for coding the behaviors was developed. The reliability of the instrument was established on the basis of computed coefficients of interobserver agreement
