Under the tide of "Internet+ education", the new means of information technology education is constantly used in education and teaching, and the traditional teaching models and teaching methods urgently need to be changed. There is no doubt about the integration of online teaching and offline teaching. On the basis of reviewing the research on the mixed teaching model at home and abroad, this paper puts forward the idea of constructing the mixed teaching model in colleges and universities in the context of "Internet+", and sets up the mixed teaching model in colleges and universities in the context of "Internet+". Through the detailed and concrete design of the operation process of the mixed teaching model, we can break the single shackles of online teaching and face-to-face teaching, and form an interactive and collaborative teaching ecosystem to realize the common development of online teaching and offline teaching.
