文摘The shared course and flipped course of Modern Educational Technology were constructed and applied based on the wisdom tree platform.The OMO teaching mode of"two courses,three links and two main subjects"was constructed according to the course teaching practice,and the teaching practice was carried out.The main teaching links and teaching quality assurance system of the mode were expounded and the application effect was analyzed from the three aspects of student evaluation,course performance and course goal achievement value.The problems in the application of the mode were discussed,and some improvement measures were put forward from the aspects of students,teachers and schools.
