There are several subjects discussed in this research: (1) developing the learning contents for repairing automotive chassis; (2) building the virtual and interactive platform for browsing and practice of troubleshooting; (3) creating the online evaluation tools and effectiveness analysis. Meanwhile, the framework has been tested and implemented in the course, "Automotive Practice: Chassis," in the spring semester of 2004. The platform developed is not dependent on specific automobile style and software configuration and it uses open software (e.g. Java, VRML, PHP, MySQL, etc.) in the virtual display and data storage.

The system can achieve the advantages and goals of (1) constructing a web-based troubleshooting architecture of automotive chassis that can enhance learners? knowledge and promote practical technologies; (2) providing references for drivers in self-detection of general chassis problems to raise driving safety; (3) creating a prototype environment for distance learning to eliminate the limitation of space and time on learning; (4) raising the learning effectiveness and motivation of on-site and distant learners.
