This paper describes an approach to implementing web-based-training (WBT) environments using the Virtual Reality Modeling Language (VRML) and Java. A VRML enabled web browser provides an interactive 3-dimensional (3-D) world where the user can learn by discovery and by doing. A Java expert system adds the ability for the practice environment to use reasoning to coach and guide the learning process. Integrating an expert system with a VRML world provides dynamic assessment and coaching so the user can analyze his actions in the 3-D VRML world. A mechanical skills training example is used to illustrate these concepts.
