A Study on Trilingual Teaching Mode of English Class in Ethnic Areas under The Multimedia Network Environment

In view of the actual needs of trilingual teaching in ethnic areas, a network English multimedia teaching system is designed and developed based on the shortcomings of traditional multimedia network teaching system, which is combined with software engineering method and based on B/S mode of J2EE technology. This paper mainly discusses the technology, architecture and implementation of J2EE, and discusses the technology and implementation of J2EE. According to the requirements of software engineering, the outline design and detailed design of the network teaching system based on UML and the concrete implementation in the object-oriented development platform are completed and the preliminary teaching practice of the system is completed. Then an online teaching application platform with interactive multimedia function is designed and implemented, and the function of multimedia network classroom is realized. Finally, the whole test process is summarized, and it is proved that the scheme can provide reliable technical support and strong technical support for teachers to perform multimedia teaching activities smoothly in online classroom.
