In the Tokyo Institute of Technology, a TV Transmitting Instruction System was planned to set up between the two campuses at 30 kilometers apart from each other. A simulation experiment was conducted in 1974 in order to investigate the possibility of lecturing at a distance. A series of televised lectures on educational psychology under the following conditions : (1) with the professor's face on one TV monitor and two types of instructional material on the other two TV monitors, (2) with any two TV images frozen by the use of a video memory unit and any single moving image on three TV monitors, (3) with no professor's face but two types of instructional material on two TV monitors, and (4) with the professor and two types of instructional material on two TV monitors in ordinary classroom. Their educational effectiveness were compared. There were no significant differences in academic achievement among the four groups. But there were significant differences on some items between (1) and (3). The conclusions were : (1) that the professor's face is assumed to be important to make a lecture more attractive and more impressive, (2) that it is possible to use a one-channel communication system with a video memory unit without reducing the attractiveness and positive impressions of the lecture, and (3) that a professor should ask the students to answer questions and ask them to discuss problems with each other in the case of condition (3). On the basis of these results, we are planning to set up a new lecture transmitting system between the main campus and remote campus at a distant of 30 km.
