Abstract
In this paper, we propose a unified synchronous/asynchronous distance learning support system using real-time editing method of teaching materials. In the real-time editing method, teachers first create teaching-material files to which the content elements constituted for every lesson subject are classified and registered. Next, teachers input editing commands on the internet during the lecture and edit teaching materials on real time with editing software, and transmit them to remote students. By sending the teaching material files to the student side beforehand, and performing teaching-materials editing software on the student side, it becomes possible to display teaching materials on the student side only by the command input from the teacher even if in the low speed network. In this way, teachers are able to reflect students' questions of an asynchronous manner and reactions during classes into editing of teaching materials. In this paper, we describe details of the proposed method and the results of the experimental evaluations.
