Abstract
At present, the network learning resource architecture mostly stays in the category of individual learning, focusing only on the listing and display of knowledge, but rarely to reflect the problem context, it is difficult to motivate learners’ active exploration and learning interaction. This paper aims at the analysis of learning and interaction activities based on the problem context, realizes the construction of learning and interaction level model caused by the problem situation, and reveals the five interaction levels of the model from low level to high level. Further more，to discuss the research value of problem-based learning and interactive behaviour in the network virtual environment by using the teaching case of the interactive simulation teaching system of aircraft virtual assembly and driving operation.

It refers to the computerized world using virtual technology, which is mainly composed of multiple computers, virtual technology interface and network technology, such as local area network, World Wide Web (WWW), etc
Summary
It has been 30 years since American scholar Neil first proposed the concept of "virtual environment" in 1989. A virtual environment refers to the three-dimensional world in which users can integrate and experience their own existence under the user-friendly virtual technology interface, which is mainly composed of the interface of "computer + virtual technology". During the use of virtual reality technology, users can browse virtual objects in virtual space, and the virtual environment created by the application of virtual reality technology can make users feel their own existence environment and activities. (1) Immersion: the "virtual" concept of virtual reality technology is mainly because the presented environment does not exist in reality, only the virtual world created by computer technology, so users will be immersed in the virtual space. (2) Interactivity: interactivity mainly refers to the user's operation of objects in the virtual world, which can get feedback from the environment, such as communicating with others in the real life environment. Virtual learning with the help of virtual environment has become an inevitable trend of learning methods
