This study investigated the communication styles of 5 mentors in telementoring a class of 33 preservice teachers. Electronic forum was the instrument of communication between the mentors and the students, and a Web-based computer mediated communication system was used to facilitate the instruction in the course. Data collected in an 8-week period resulted in 52 mentors initiating discussion threads and 43 follow-up posts. Analysis of the 5 mentors' 52 initial thread generating posts revealed 4 styles: the direct questioning, context explaining, experience sharing, and greeting styles. It was found that the five mentors most often posted a question in straightforward fashion (direct questioning). Context explaining was also used quite often. On the follow-up posts, it was found that 6 categorical styles exist among the 43 posts: the direct answering, suggesting, agreeing, summarizing, relating, and questioning styles. In this study, the agreeing, the relating, and the direct answering styles were used most often. It seemed that the follow-up posts in these three styles were easier to generate.
