a real-time interactive shared system for distance learning
DESCRIPTION
The greatest obstacle in developing distance learning system is the lack of real-time interaction. This paper provides a real-time interactive shared system for distance learning that combines the audio, video and seminar. The remote learners can study and exchange opinions with the instructor through this system in real time. After the test between Waseda University and Guilin University, we find that the system can well simulate traditional classroom and improve interaction among participators, which not only saves learners’ study time and improves their learning interests and efficiency, but also improves the teaching freedom of instructor for e-whiteboard is introduced.TRANSCRIPT

Background (Cont.)
Constant changes in technology Learners have no enough time staying at
classroom Technology of Computer & Communication Distance education system When separated with instructor by space
and/or time, learners staying far away can participate in a course on-line or off-line.

Background Two main characteristics:
(1) seeing & hearing
(2) shared activity-
question-answer, e-board, documents, data interaction, BBS, etc
Interaction among participators (1) asynchronous information exchanging (2) synchronous information exchanging (3) collective discussion (4) collaborative environment

Shortcoming
Learners can’t use the e-board, the instructor can’t see the facial response of learners to his class, and so on.
