| Abstract: | Based on the theories and concepts of CSCW, an electronic whiteboard system which is suitable for the real time online communication between teachers and students is discussed. The 3-tier architecture based on B/S is adopted, and organized by modules. For concurrency controlling, the lock scheme is used; the multicast technology is also used to improve the efficiency of communication and to achieve the consistency. Finally, the implementation of the system is presented, and some key points of modules are introduced. The test of the prototype system proves that the platform is convenient for installing and upgrading client software, and is applicable to large scale real time online communication in the remote education activities. |
