From the point of view of modern educational technology development, the development process CAI from single computer to network is introduced. Through the induction of learning theory and education theory in different stages, the modern CAI and its main development mode are analyzed. Combining with computer software technology and network technology development, the system design of an open CAI platform is put forward. Using the network platform, the basic concepts and theories requirements of modern education theory and learning theory are realized. Using clustering algorithm and rough set theory, the application of network learning theory and design principle in CAI is studied. The results show that, with the continuous development of network technology, application of network learning theory and design principle in the fields of CAI will play an increasingly important role. In conclusion, in the near future, a truly mature and open learning environment will be able to build to achieve the greatest range of educational resources sharing, which makes the popularity of CAI into reality.
