This study was designed to determine whether there was a
difference in either the overall frequency or the
frequency of specific types of student verbal
interactions under three conditions: (1) teleconferenced
instruction where students had two-way audio and video
contact with the instructor; (2) teleconferenced
instruction where students had only two-way audio contact
with the instructor; and (3) traditional face-to-face
instruction. Hypotheses tested by the study related to
the numbers of verbal interactions in each of the three
conditions, including restricted and expanded thinking
questions and responses (Equivalent Talk Categories--
ETC's). Subjects were 172 students enrolled in Classroom
Educational Technology at the University of Northern
Colorado, who were assigned to one of three treatment
groups. Two-way audio and video teleconferencing
facilities between two buildings on UNC's Greeley campus
were utilized to deliver instruction for the two
experimental groups; the third group received face-to-
face instruction via lecture. Two lessons were presented:
"Topics in Distance Education," which utilized handouts
with true-false questions, open-ended questions, and case
studies; and "Copyright Issues for Using Videotapes in
the Classroom," which was videotaped and coded according
to ETC's. One-way ANOVA's and t-tests were conducted for
each of the ETC's. Results indicated that the
experimental groups did not differ significantly in any
of the ETC's or in the total number of interactions, and
that the traditional (control) group generally interacted
more than either of the teleconference groups both in
terms of total number of interactions and in several of
the ETC's. It is recommended that future studies focus on
the role of nonverbal interactions in visual delivery
modes. (10 references) (BBM)
