摘要

本文提出了一种用于开发在线培训系统的在线教学知识建模方法。为了克服在线教学知识获取和验证的困难，我们使用Petri网理论作为工具来指定和验证各种培训计划和相应的培训场景，从而获得在线教学知识。基于虚拟现实的数控(CNC)操作培训系统的实验实例表明，基于Petri网的培训任务和培训场景分析可以促进在线培训系统知识库的创建。

Modeling online instruction knowledge using Petri nets

This paper presents an approach to modeling online instruction knowledge for developing online training systems. To overcome the difficulty in online instruction knowledge acquisition and verification, we use Petri nets theory as a tool for specifying and verifying varied training plans and corresponding training scenarios whereby the online instruction knowledge is derived. An experimental example, the virtual reality based computerized numeric control (CNC) operations training system, shows that Petri nets based training tasks and training scenarios analysis can facilitate creating a knowledge base of online training systems.
