To test the impact of video feedback on teachers' eye-contact mannerisms in microteaching in inservice vocational teacher education, the study utilized video recordings from the data bank generated by previous studies conducted at the Ohio State University's Center for Vocational and Technical Education. The tapes were assigned through a stratified random selection to two treatment groups, one with and one without video feedback. Pretest and posttest eye-contact measurements were made from the tapes by two panel members using stop-watches. Through covariance analysis, the groups were compared on their introduction, presentation and summary, and a combination of these parts. The reliability coefficients of the ratings were between .95 and .99. There were not significant differences at the .05 level between teachers who received video feedback and those who received no video feedback in their eye-contact mannerisms. It was concluded that the video feedback may not have any significant effect on eye-contact mannerisms. This Ph.D. thesis was submitted to The Ohio State University. (GR)
