The purpose of this system is to establish virtual medical school (VMS) as the platform of e-Iearning center, which integrates collaborative and self-directed learning environment by virtual group, classroom and library, and automatically converts valuable clinical case from Hospital Information System (HIS) database into virtual patient by online authoring tools for problembased e-leaming. In this system, the VMS provides a problembased e-Iearning environment, and utilizes HIS to capture and store valuable clinical cases. All medical students and residents now have the opportunity to learn from these typical cases on line. The VMS at National Taiwan University has the potential to develop into a national medical education networkfor the mediation and provision of comprehensive medical resources. The system will use the international standardSCORM 1.2to develop teaching material and assist with the HL7 v2.4, CDA vl.O standards to connect Electronic Medical Record (EMR) systems in the hospital. It can provide resources sharing among medical centers by using high transportation ability of Grid Computing integrated with the broadband video platform, Access Grid, and personal multiple point videoconference platform, Multi-video, to popularize the application of e-Iearning in clinical medical education.
