Such new IT mostly comes from foreign countries and the technical manuals about how to learn such new IT and how to use its latest development tools in English. In this paper, combined with previous teaching experience and the development of a large number of networked multimedia, a preliminary study carried out on the interactive network multimedia education platform design patterns, the overall structure and system solutions. As the study is only a tentative teaching experiment based on the collaborative teaching mode, necessary improvement and modification are needed in other teaching practice. According to the curriculum characteristics and teaching situation of computer professional English, propose some teaching innovation scheme in terms of teaching contents and teaching methods, and combine computer professional English with computer professional courses to strengthen student application ability and improve teaching quality effectively.展开更多
