In order to determine the feasibility of bringing outstanding teachers to the high school classroom, 5 small Colorado schools examined multi-school sharing of information through use of long-distance conference telephone calls. Three of the experiments involved college professors lecturing via telephone to high school students in American History classes. The students responded with questions, thus creating a limited 2-way communication which is not possible with television, tape recorders, and radio media. The instructors felt that their students benefited from the experiments and that telephone use has many unexplored possibilities as a teaching device. The document is appended with project costs (financial and technical assistance was provided by the Mountain States Telephone Co.) and with the questionnaires used in evaluating the study. (AN)
